Introduction

SINVAC HDPE Structured Wall Pipe

5

HDPE Structured Wall Pipe represents the

latest advancements in material and

manufacturing technology. Raw material

properties and product technology have

been combined to provide a light-weight

engineered pipe for various gravity and

non-pressure applications in the

municipal, industrial, road construction,

rehabilitation and marine pipeline

applications.

HDPE Structured Wall Pipe is now the

front runner in replacing traditional pipe

system materials like concrete, CMP

(corrugated metal pipe) and PVC

(polyvinylchloride).

HDPE Structured Wall Pipe is

manufactured through a specially

designed profile extrusion process where

a square or rectangular profile is extruded

and spirally wound onto a mandrel. The

overlap on the edge of the extruded

profile is fused homogenously together

whilst still in the hot plastic state to create

a smooth internal surface.

This results in a light-weight HDPE

Structured Wall Pipe which has all the

advantages of a normal solid-wall HDPE

pipe but with added benefits of being

light-weight, easy to transport and install,

which then makes it an obvious choice for

gravity and non-pressure applications.

HDPE Structured Wall Pipe is normally

defined by the inside diameter and the

ring stiffness for the desired application.

With pipe ID range from 300mm to

1200mm and ring stiffness of 4kN/m²or

8kN/m².

SINVAC has the capacity to manufacture and supply HDPE

Structured Wall Pipe with ID range 300mm to 1200mm and

ring stiffness of 4kN/m2 and 8kN/m2 at very competitive

prices. HDPE Structured Wall Pipe represents the

latest advancements in material and

manufacturing technology. Raw material

properties and product technology have been combined to

provide a light-weight engineered pipe for various gravity and

low pressure applications in the municipal, industrial and road

construction, rehabilitation and marine pipeline applications.

Advantages of HDPE Structured Wall Pipe:

• Typically weighs less than 10% of equivalent concrete

pipe.

• HDPE has excellent chemical resistance to most

industrial and domestic wastes.

• HDPE is five times more abrasion resistant than

concrete.

• HDPE has a lifespan of up to 100 years.

SINVAC offers custom fabricated HDPE Manholes for a variety of applications. Manufactured

from a combination of high quality solid-wall and structured wall pipe. SINVAC HDPE

Manholes are resistant to root ingress, preventing contamination to surrounding groundwater

and providing a watertight structure that delivers an extended life expectancy, making them

suited for sewer and stormwater applications.

SINVAC HDPE Manholes are prefabricated , which eliminates the risk of deformation in the

structure. The shaft configuration of the manhole can also be adapted to accommodate many

applications and an HDPE ladder can be fabricated for the inside of the Manhole.

The SINVAC Coupling and Seal socket joint must always be carried out in accordance with

sound civil practice.

The following is recommended:

• Clean the pipe end, the coupling and the seal, removing any foreign matter, water, sand,

dirt, etc.

• Make sure the seal sits correctly in its location.

• Apply lubricant over the end of the pipe with seal and coupling end, as appropriate.

• Carefully align the coupling and seal end with each other, then push to the required

insertion depth.

• If a lever is used on the pipe to push the joint, insert a block of wood between the lever

and the end of the pipe to prevent damage to the pipe.

SINVAC manufactures the HDPE

Sleeve in-house. We then

extrusion weld the one end onto

the first Structured Wall Pipe.

The second pipe is then inserted

into the HDPE Sleeve on-site and

is also extrusion welded to form

a watertight joint.

The Clamp Joint Method is

designed for jointing pipes in

stormwater and other types of

non-pressure application, repair

of existing pipelines and

maintenance of pipelines. Used

as a joint for plain ended pipes.

Hydraulic Design

SINVAC HDPE Structured Wall Pipe has a low friction coefficient,

owing to HDPE having a low friction coefficient.

Manning’s Roughness Coefficient value of n=0.03 is used for pipes

with full flow as per below graph.

Pressure Test

Reason: (HDPE Structured Wall Pipe is used for non-pressure

application. Pressure Test conducted as experiment)

• A pressure test was conducted on the 4kN/m2 Structured Wall HDPE

Pipe, with Inner Diameter of 560mm.

• The Cylinder, as per Figure 1.1, was filled with water. Additional water

was pumped in with a water pressure pump, until required pressure was

reached.

• The result obtained in the experiment, is that the Extrusion Weld and

Structured Wall Pipe can handle at least 1.5 bar pressure, as per

Figure 1.2, without leaking.
