1.Easy to install2.Fire resistant3.High pressure durability4.Structure avoids stress concentration5.Allows partial replacement of pipe system6.Free from flow and buoyancy when using mixing machines, etc7.Predictable movement by fixed pipe structure allows easier
designing and engineering of Floating Roof Tanks 8.NIIGATA double seal type swivel joint prevents leakage for a long time
Floating roof tanks are usually required to endure more than 30years.Our Roof drain system accomplished high reliability and durability by using NIIGATA Swivel Joints
1.Universal 360-degree rotary pipe joint with double row ball bearings.
2.Two-square symmetric structure disperse force concentration which is loaded on swivel joints and long pipe structure absorb unpredictable force direction.
3.BD type has been developed specifically for floating roof tanks. It has a special double-seal structure,which enable it to withstand external pressure with long service life.BDR type is an upgraded version of BD type with a prolonged lifetime through a triple-seal structure of X-rings,and extended stainless-steel cladding.
4.Stainless-steel cladding(see right figure below,with red color)Sealing surfaces with stainless-steel cladding make them highly resistant to corrosion.
