Frequently Asked Questions
What is ERW steel pipe?
ERW stands for Electric Resistance Welded. It is a type of steel pipe manufactured through cold-forming a sheet of steel into a cylindrical shape and then passing an electric current to heat the edges and weld them together.
What standards do your ERW pipes comply with?
Our pipes comply with international standards including ASTM A53, API 5L, EN10217, and EN10219, covering various grades like Grade B, X42, and S355.
What are the available surface treatments?
We offer various surface treatments such as black painting, galvanization, 3PE (Three-Layer Polyethylene), 3PP, and FBE (Fusion Bonded Epoxy) coating to prevent corrosion.
What size range do you provide for ERW pipes?
We provide ERW pipes with an outer diameter ranging from 0.5 inch to 26 inches and wall thicknesses from 1mm to 18mm.
How do you ensure the quality of the pipes?
Every pipe undergoes rigorous testing, including hydraulic testing, ultrasonic testing, or X-ray inspection. We also accept third-party inspections from SGS, BV, or INTERTEK.
What are the typical applications of these pipes?
These pipes are commonly used for fluid transmission (water, gas, oil), structural purposes in construction, boiler pipes, and in the chemical industry.
