Product introduction
Product Description
ERW High Frequency Welded Steel Pipe 76-660mm ASTM A53 Carbon Steel Pipe is a full-size series high-frequency electric resistance welded straight seam pipe strictly manufactured in compliance with ASTM A53/A53M standard Type E ERW. The outer diameter covers 76mm to 660mm, covering medium and large mainstream calibers for global engineering projects, with Grade A & Grade B carbon steel available as standard raw materials.
Adopting fully automatic high-frequency solid-state welding technology, the weld realizes complete metallurgical fusion with base metal, equipped with online internal & external burr removal to form smooth burr-free inner bore. All finished pipes pass 100% full-length hydrostatic pressure test and weld online eddy current ultrasonic NDT inspection, stable airtightness and pressure resistance. Multiple surface treatments including black anti-rust oil, hot dip galvanized, 3PE/FBE anti-corrosion and internal epoxy lining are optional, suitable for buried, overhead, pipe gallery and indoor laying. Widely used for water supply, gas transmission, fire protection, industrial fluid delivery and building structural projects, we are a professional one-stop ASTM A53 ERW pipe supplier with complete specifications, stable stock and customized processing service for global buyers.

Adopt flux-free solid-state high-frequency resistance welding without welding filler metal, weld grain recrystallized to match base metal strength. Online weld stress relief eliminates residual stress to avoid delayed cracking. 100% hydrostatic test + eddy current ultrasonic weld inspection eliminate pores, slag inclusions and microcracks, fully meet long-term fluid transmission safety requirements.
2.3 ASTM A53 Standard Carbon Steel, Balanced Strength & Weldability
Grade B as mainstream option provides minimum yield strength 240MPa, tensile strength ≥415MPa, excellent toughness and weldability; Grade A for low-pressure lightweight structural projects. Strict control of carbon, manganese, sulfur and phosphorus impurities, stable batch mechanical performance, suitable for welding, threading, grooving and all common construction connection methods.
2.4 Smooth Inner Wall, Low Fluid Transmission Resistance
Online mechanical removal of internal welding flash completely eliminates inner burrs, flat smooth inner surface reduces fluid friction loss, avoids sediment and impurity accumulation inside pipes, stabilizes water/gas flow pressure and cuts long-term pump energy consumption of municipal and industrial pipeline systems.
2.5 Diversified Anti-Corrosion Customization for All Working Environments
Multiple mature anti-corrosion systems to match different laying conditions: hot dip galvanized for overhead atmospheric anti-rust; 3PE for buried soil anti-corrosion; FBE for high-temperature and coastal saline soil; internal epoxy lining for clean tap water delivery, extending pipeline service life up to 30–50 years.
2.6 Factory Direct Supplier, Stable Supply & Competitive Price
