API 5L PSL1 PSL2 EN10210 ASTM A500 ERW Steel Pipe
ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
Our product finds its usage for Agricultural purposes, Drinking Water for housings, in collieries for extraction of Water, Thermal Powers, Transports, Hand pumps for deep boring wells, as a strong protection for cables by Telecom Department, Structural Purposes etc.
ASTM A500 structural pipe is a standard specification for cold-formed welded structural tubing produced to round nominal pipe sizes. ASTM A500 is the most common specification in North America for Hollow Structural Sections. Since ASTM A500 is a structural specification, round pipe HSS produced to this specification is a fit for applications being used in structural applications and general construction use. The tolerances of A500 are tighter than those of A53, therefore the A500 round pipe HSS has more quality and less variability than A53. Round HSS pipe has a superior surface finish and does not come with a lacquer coating. A500B Structural Pipe is manufactured for use in applications that demand greater strength, closer tolerances, and a superior finish. This product is an excellent choice for painted applications.
MANUFACTURING PROCESS
ASTM A500 structural pipe is welded pipe sized tubing made from flat-rolled steel, formed through a roller system and welded using electric-resistance welding. Longitudinal butt joints of welded tubing shall be welded across its thickness in such a manner as to assure the structural design strength of the tubing section. Welded structural steel pipe is normally furnished without the removal of inside flash.
