2.5 Base materials / Ancillary materials The base material for manufacturing hot-rolled coils as a preliminary material for cold- and hot-finished hollow sections is iron (percentage by mass >= 99.5%). Other primary components are carbon, silicon and manganese. Chemical composition varies depending on the steel grade. The detailed percentages by mass are indicated in the /DIN EN /10210-1/ and /DIN EN 10219-1/ product standards. Ancillary materials:Various lubricants depending on the respective rolling process 2.6 ManufactureHot-rolled strips of appropriate width and sheet thickness, wound as coils, serve as the preliminary material for manufacturing longitudinal welded steel pipes at the pipe manufacturer, Mannesmann Line Pipe. There are two production facilities with identical manufacturing methods located in Siegen and Hamm.

Pipe production (circular hollow sections)The process is divided into three phases: forming connected strips to an open V-shaped pipe, welding and annealing the seam in order to achieve the appropriate micro structure. The heated strip edges are welded together by pressing. The pipes are rounded and straightened followed by non-destructive testing of the HFI seam. The pipe string is then sawn to the required length for the desired round hollow section.

Processing (hot-finished round, square and rectangular hollow sections)The cold-finished circular pipes referred to above are heated to more than 870 °C solid body for manufacturing hot-finished circular hollow sections and for reforming as square and rectangular sections using four inductors. Production speed ranges from 0.5 to 4.0 m/min.

Both sites are certified to /DIN EN ISO 9001/ and /API Q1/ for product manufacturing and quality assurance.

2.7 Environment and health during manufacturing

During the entire manufacturing process, no other health protection measures are required extending beyond the legally specified industrial protection measures for commercial enterprises. Certification of industrial safety and health protection in accordance with /OHSAS 18001/ is in place for both sites. Via regular analyses of the environmental impacts and permanent improvement measures and action within the framework of TQM (Total Quality Management), the low environmental impacts attributable to the manufacturing process are continuously minimised. Both production facilities operated by Mannesmann Line Pipe GmbH are certified according to /ISO 14001/.

2.8 Product processing/InstallationProcessing recommendations: Hot- and cold-formingHot- and cold-forming are possible without any difficulty. Hot-forming should be carried out in a range of 1,050 to 750 °C. Forming steps largely involving compression, i.e. forging, can be carried out in the upper temperature range while the lower temperature range should be used for those involving stretching. The temperature can decrease to 700 °C for degrees of deformation of less than 5% in the final stage. This must be followed by air cooling. After hot-forming, normalising is necessary if temperatures arose outside the temperature range of 980 to 850 °C during the previous forming process. After stronger cold-forming processes requiring heat treatment in accordance with the respective guidelines (/AD data sheets/), stress-relief heat treatment is often sufficient unless other acceptance test procedures or other specifications expressly demand normalising. WeldingThe steels can be welded manually or automatically after each of these procedures. At external

4 Environmental Product Declaration Mannesmann Line Pipe GmbH – MSH Sections

temperatures below approx. +5 °C and wall thicknesses exceeding 50 mm (for S 355 and higher exceeding 30 mm), preheating of a sufficiently wide zone to 80 to 200 °C is recommended. In any case, the surface should be moisture-free. Stress-relief heat treatment (see heat treatment) is not generally necessary. It should only be carried out if demanded by a construction regulation or when welded constructions and/or operating conditions commend a reduction of internal welding stresses. Appropriate welding consumables shall be used for arc welding; basic electrodes shall be used for grades with a specified minimum yield strength of 355 N / mm² or more. Industrial health and safety protection measures: No health protection measures over and beyond the standard industrial safety measures (e.g. protective gloves) are required during processing/installing the MSH sections. Environmental protection measures:No noteworthy environmental pollution is triggered by processing/assembling the products in question. No special measures need to be taken to protect the environment. Residual material incurred:Residual and packaging material incurred on the building site must be collected separately. The specifications of local waste authorities must be maintained during processing.

2.9 PackagingMSH sections (angular or circular) are bundled using steel bands and/or shipped on wooden beams, secured with wooden wedges (waste code nos.: 150103 packaging made of wood, 150104 packaging made of metal). All packaging can be re-used.

2.10 Condition of useContents in condition of use:The material composition during the utilisation phase corresponds to that at the time of production. MSH sections are manufactured from non-alloy structural steels and fine-grain structural steels in accordance with /DIN EN 10 210-1/ and /DIN EN 10219-1/. Contents are listed in Table 2.1 in section 2. Corrosion protection:Detailed information on corrosion protection is available in the technical information sheet entitled “Protecting hollow sections from corrosion” on /MLP/.

2.11 Environment and health during useGeneral health and environmental aspects:There are no health risks for users of MSH sections or for persons manufacturing or processing MSH sections. From an environmental perspective, there are no restrictions governing the use of MSH sections.

2.12 Reference service lifeBuilding product life cycles are dependent on the respective building design, use and maintenance. The use phase for structural hollow sections is not depicted as they involve maintenance-free and generally durable products.

2.13 Extraordinary effects

FireMSH sections comply with the requirements of construction product class A1 “non-flammable” in accordance with /DIN 4102, Part 1/ and /DIN EN 13501-1/. No smoke gas develops. Fire protectionName ValueBuilding material class A1

WaterThe effects of flooding on MSH sections neither lead to any changes in product reliability nor to any other negative environmental Impact.

Mechanical destructionIn the event of extraordinary mechanical impact, steel structures display very good characteristics thanks to the high degree of ductility (plastic deformation) of the material. In general, no chips, breaking edges or similar exist.

2.14 Re-use phaseMSH sections are 100% recyclable. The MSH sections used in a structure are only partially re-used after demolition; the largest share is primarily directed to electro-steel plants as scrap.

2.15 DisposalAs steel is 100% recyclable, this material does not require disposal.Waste code in accordance with the European List of Wastes (EWC), as per the European List of Wastes Ordinance /AVV/: 17 04 05 Iron and steel.

3.2 System boundaryType of EPD: cradle to plant gate – with options The EPD comprises the following life cycle phases:

Product stage (Modules A1-A3) End-of-life stage (Module C3) Benefits and loads beyond the system

boundary (Module D)

5 Environmental Product Declaration Mannesmann Line Pipe GmbH – MSH Sections

Modules A1-A3 comprise both the upstream chain of production and provision of raw materials, ancillary materials and energy resources as well as transport thereof to the plant and the energy expenses incurred there. Furthermore, waste water treatment is considered.It is assumed for Module C3 that there are no other material or energetic expenses for waste processing.Module D takes consideration of the re-use and recycling potential.

3.3 Estimates and assumptionsThe base material for manufacturing MSH sections is low-alloyed hot-rolled coils via the furnace route with production facilities in Germany.The production of hot-rolled strips is represented by a generic and /EN15804/-conformant GaBi data set /GaBi ts/.

3.4 Cut-off criteriaThe end-of-life scenario involves product losses of 1%. Landfilling is ignored. Likewise, the manufacture and utilisation of packaging material (steel bands, wooden beams) are not considered. Nor is the use of lubricants taken into consideration. Nevertheless, in total these neglected flows significantly comply with the cut-off criterion of max. 5% of energy and mass expenditure while also adhering to the criterion of 1% in relation to individual processes, /PCR, Part A/.

3.5 Background dataThe LCA results of the declared product are based on modelling in the /GaBi ts/ software environment. Modelling depends on primary production data and the energy and media consumption values for an entire year.This was supplemented by basic materials in the GaBi data base. The respective documentation can be reviewed online.

3.6 Data qualityThe primary data used refers to fiscal 2012. The annual volumes have been examined for representativity in relation to previous years.The GaBi data base (DB version 6.115, SP 29) /GaBi ts/ with the corresponding basic material data sets was last updated in 2016.

3.7 Period under reviewThe period under review is fiscal 2012. The volumes of hot-finished MSH sections produced in 2012 serve as averages for the Declaration.

3.8 AllocationBy using the “Steel hot-rolled coil /EN15804 A1-A3/” /GaBi ts/ data set, indirect allocations are applied by mass, market value, calorific value and exergy in Module A1. The use of steel scrap for the production of hot-rolled coil is regarded as unencumbered for Modules A1-A3. However, a large percentage of scrap requirements is already covered by the cutting losses incurred during pipe production. In a consideration of the end-of-life scenario, the remaining requirements are initially covered by scrap volumes incurred after the use phase. The difference is represented by the net scrap volume which is neither directly re-used nor recycled /ECSC/ (see section 4). If re-used, this scrap percentage is credited to pipe production (A1-A3). Recycling credits are allocated in line with the “theoretically 100% primary blast furnace route” approach, /Worldsteel 2011/.

3.9 ComparabilityBasically, a comparison or an evaluation of EPD data is only possible if all the data sets to be compared were created according to /EN 15804/ and the building context, respectively the product-specific characteristics of performance, are taken into account. The used background database has to be mentioned.

6. LCA: Interpretation

A detailed analysis of the environmental impacts in terms of the LCA of the product under review following classification of the Life Cycle Inventory Analysis flows indicates the strong influence of hot-rolled steel strip production (A1) on the production stage as a whole (A1-A3, see graphic). Apart from ADPe (Abiotic Depletion Potential for non-fossil resources), the remaining environmental impacts are dominated by more than 85% by steel production. With the exception of electricity consumption, the remaining categories play an insignificant role. Accounting for a share of more than 75% of entire electricity consumption, these environmental impacts can be largely attributed to the HFI pipe welding process.

Around 80% of the ADPe impact category is determined by electricity consumption and in equal

parts by upstream steel production and downstream waste water treatment.

Transport, both to the plant site (“transport” category) and within the plant (“diesel” category), has practically no influence on the LCA results. The same also applies for the “auxiliaries” and “natural gas” categories.

7 Environmental Product Declaration Mannesmann Line Pipe GmbH – MSH Sections

Environmental impacts of Modules A1-A3

Steel – as a material with inherent properties – is infinitely recyclable. Therefore, the aim when analysing steel products is to consider end-of-life scenarios in particular and analyse them comprehensively across all life cycle phases.

Recycling is carried out in an established electric arc furnace (EAF) process.

The substitution of primary steel production gives rise to LCA advantages as the loads incurred by the

expenses associated with primary steel production are offset against relatively low loads incurred during recycling. The Global Warming Potential (GWP) result for Module D, for example, represents the total loads and benefits. In combination with very high collection rates, this generally results in high credits for steel products during the end-of-life phase. Only the ODP (Ozone Depletion Potential) category is attributed additional loads by recycling. These can be attributed to the increased use of electricity by the EAF route compared to the furnace route.

Environmental impacts, incl. Module D

7. Requisite evidence
