ERW carbon steel pipe, also known as straight seam welded pipe, is manufactured by cold-forming steel strip or steel plate into a cylindrical shape and then welding the seam. The weld seam runs parallel to the longitudinal direction of the pipe. This production process is simple, highly efficient, and cost-effective, making ERW steel pipe one of the most widely used pipe products in the global market.

Our ERW carbon steel pipes are available in a wide range of sizes: outer diameter from 21.3mm to 323.8mm, wall thickness from 1mm to 22mm, and length from 1.0m to 12.0m or customized. The pipes are manufactured in compliance with international standards including ASTM A53, ASTM A500, API 5L, API 5CT, GB9711.1, and DIN/BS/JIS/AISI/EN.

With a hot-rolled surface finish, tight dimensional tolerance of ±1%, and non-oiled treatment, these pipes offer excellent weldability, structural strength, and corrosion resistance. They are widely used in fluid transportation, structural support, boiler pipes, drill pipes, hydraulic systems, gas pipelines, oil pipelines, and construction projects.

FAQ

Q1.: What is the difference between ERW pipe and seamless pipe?

KEI: ERW (Electric Resistance Welded) pipe is manufactured by forming steel strip into a cylindrical shape and welding the longitudinal seam. It is more cost-effective, has consistent wall thickness, and is suitable for most general applications. Seamless pipe is manufactured without any weld seam, offering higher pressure resistance and better performance in high-temperature and high-pressure environments, but at a higher cost. For most fluid transmission, structural, and construction applications, ERW pipe provides an excellent balance of performance and economy.

Q2.: What standards do your ERW carbon steel pipes comply with?

KEI: Our ERW carbon steel pipes are manufactured in compliance with multiple international standards including ASTM A53, ASTM A500, API 5L, API 5CT, GB9711.1, MAI, BS, JIS, AISI, kei na EN. We can supply pipes according to the specific standard required for your project.

Q3.: What sizes are available for ERW carbon steel pipes?

KEI: We offer a comprehensive size range: outer diameter from 21.3mm to 323.8mm (1/2″ to 20″), wall thickness from 1mm to 22mm, and length from 1.0m to 12.0m. Custom sizes are also available upon request.

Q4.: What is the delivery time for ERW steel pipes?

KEI: For standard specifications with stock available, delivery can be completed within 7 days. For custom specifications or large orders, the delivery time is typically 15-21 days. Please contact us for specific delivery schedules based on your order quantity and specifications.

Q5.: How are the pipes inspected before shipment?

KEI: Each batch of pipes undergoes rigorous inspection including: chemical composition analysis, mechanical property testing, dimensional and appearance inspection, and non-destructive testing (NDT). All inspections are conducted in accordance with the applicable standard requirements to ensure product quality and reliability.
