Stainless Steel Pipe Spools

Prefabrication Flanged Spool Pieces
Material: SS2205, SS316, SS304L, 254SMo, etc.
Application: Marine industry
Description
The Stainless Steel Pipe Spool is a relatively short component, consisting of a pre-determined length of pipe welded to a specified pipe fitting (tee, elbow or reducer) or valve (gate or ball). The flange is usually welded to each end of the pipe.
 
Due to the excellent corrosion resistance of stainless steel, the pipeline is not easy to rust, damage or accumulate debris by wear. Electrical steel has low maintenance costs. And due to its corrosion resistance, it is unlikely that stainless steel pipes will need to be replaced for decades.
 
The stainless steel pipe spool is of prefabricated length for easy use of Tri-Clamp fittings. These pipes will construct a process line in conjunction with other Tri-Clamp fittings, clamps and gaskets, eliminating the need to weld and produce on-site, and save time significantly.
