General Introduction to Pipe & Tube

A pipe or tube is a term used to designate a hollow, tubular body which is used to transport any fluid possessing flow characteristics such as those found in liquids, gases, vapors, liquefied solid, and fine powders. The pipe can be categorized as seamless pipe and welded pipe. Welded pipes can be further classified as butt-welded pipe and spiral-welded pipe. There 3 important parameters to specify a pipe: outside diameter(O.D), inside diameter(I.D), and wall thickness(W.T). Metals-Piping supplies pipes & tubes manufactured from cast iron, carbon steel, low alloy steel, alloy steel, stainless steel, nickel & nickel alloy, titanium, aluminum, zirconium, copper and copper alloy, and cladding metals.

End Connection/Joint Types

Butt welding(BW), Threaded(Screwed), Socket Welding.

Dimension & Weight

The dimension & weight specification shall be in accordance with ASME B36.10, ASME B36.19.
