Typical Applications

Where ERW carbon steel pipe is used

Water and utility linesWater transmission, drainage, low-pressure service, fire protection, utility networks and project pipe packages where coating and pressure class are defined.
Construction and structureScaffolding, structural frames, temporary works, piling-adjacent support, handrail fabrication and general construction pipe use.
Mechanical and industrial useMachinery frames, conveyor structures, equipment supports, guard rails and industrial fabrication requiring repeatable OD, wall and length control.
ERW route note

ERW and HFW supply should be matched to the ordered standard and service. For pressure or line pipe use, confirm test scope, hydrotest, NDT and certificate requirements.

Surface and end note

Black, painted and galvanized pipe use different surface checks and packing. End finish also affects quotation, especially when beveling, threading, coupling or caps are required.

Buyer FAQ

Questions to settle before quotation

What is ERW carbon steel pipe?

ERW pipe is made by electric resistance welding from steel strip or coil. For quotation, confirm the standard, grade, OD or NPS, wall thickness or schedule, length, end finish and testing.

Which standards are common?

Common references include ASTM A53 for general pipe, API 5L for line pipe projects, ASTM A500 for structural tubing, and EN 10219 or EN 10217 for welded structural or pressure tube use.

Can ERW pipe be galvanized or painted?

Yes. It can be supplied black, bare, varnished, painted, hot dip galvanized or project coated when surface, coating thickness and inspection requirements are confirmed.

What details are needed for RFQ?

Provide standard, grade, OD or NPS, wall or schedule, length, end finish, surface, coating, test requirements, MTC level, bundle packing, quantity and destination port.
