PIPING MISCELLANEOUS AND FORGED ACCESSORIES, a type of PIPES.
Piping Miscellaneous and Forged Accessories are a type of Pipes.
In an industrial facility, process piping is the network that carries process fluids chemicals, fuels, industrial gases, water, steam and air throughout the plant for manufacturing or power generation. For line pipes the primary classification factors are the method of manufacture, whether welded or seamless, and the materials used; in addition, wall thickness is a critical criterion for seamless products because only a few suppliers can produce seamless tubes with walls thicker than 25.4?mm. From a regulatory perspective it makes sense to treat stainless and duplex steels and cladded pipes separately from other plant piping, since they are used in specialised applications and follow different requirements; high?alloy grades such as 6Mo belong here.
A further part of this subcategory deals with products requiring specialist skills to fabricate, including items made from concrete, PVC and titanium. Copper?alloy fittings brass, bronze and similar alloys are included, as are the plastics high?density polyethylene, polypropylene and polyethylene. Multilayer and non?ferrous pipes and fittings are typically composed of cross?linked polyethylene, an aluminium layer, another polyethylene layer and adhesives. Finally, simple in?line strainers intended to sit inside pipelines are grouped here; these basic filters should not be mistaken for the more sophisticated strainers found in the Packages category.
