ASTM A53 ERW Steel Pipe

ASTM A53 ERW Steel Pipe - Industrial Grade Carbon Steel Solutions

Product Overview

JS FITTINGS delivers premium ASTM A53 ERW Steel Pipe manufactured through Electric Resistance Welding technology, meeting ASTM A53/A53M and ASME SA53 specifications. Our Grade B carbon steel pipes feature uniform wall thickness and superior concentricity, designed for steam, water, gas, and air applications. With 42 years of manufacturing expertise, our 35,000 m² facility produces 30,000 tons annually using 4 advanced production lines. Each ASTM A53 ERW Steel Pipe undergoes precision heat treatment at 1000°F minimum, ensuring weld strength matches base metal performance for reliable pressure piping solutions.

Key Features & Advantages

30,000-Ton Production Capacity

Our automated production lines guarantee stable supply for large-scale industrial projects. You receive consistent delivery schedules without supply chain disruptions.

Dual-Standard Certification

Beyond ASTM compliance, our pipes meet API 5L and EN 10219 standards. This dual certification reduces your procurement complexity across different project requirements.

Precision Wall Thickness Control

Unlike extruded seamless pipes, our ERW process uses rolled sheets. You get superior concentricity and uniform wall thickness that reduces installation issues.

Enhanced Surface Quality

Our manufacturing process delivers smoother internal and external surfaces. This translates to reduced friction losses in your fluid conveyance systems.

Heat-Treated Weld Seams

Every longitudinal weld receives heat treatment at minimum 1000°F (540°C). This eliminates untempered martensite, ensuring weld strength matches base metal.

Technical Specifications

Standards & Certifications

Our production facility maintains ISO 9001, CE, and PETROBRAS certifications. Each pipe batch includes mill test certificates confirming ASTM A53/A53M compliance. Dimensional standards follow ANSI B36.10 specifications for seamless compatibility with standard fittings.

Chemical Composition & Mechanical Properties

Chemical Composition (Grade B):

· Carbon: 0.30% maximum

· Manganese: 1.20% maximum

· Copper, Nickel, Chromium, Molybdenum: 0.40% combined maximum

· Silicon: 0.40% maximum when specified

Mechanical Testing:

Every production lot undergoes tensile testing, flattening tests, and hydrostatic pressure testing per ASTM requirements.

Manufacturing Process

Electric Resistance Welding (ERW) Process:

1. High-grade steel coils undergo precision slitting

2. Forming rolls shape the strip into pipe configuration

3. Electric resistance welding creates longitudinal seam

4. Heat treatment at 1000°F minimum eliminates stress concentrations

5. Sizing and straightening ensure dimensional accuracy

Our automated painting lines and eco-friendly sandblasting systems provide consistent surface preparation.

Surface Finish & Coating Options

Standard Finishes:

· Black pipe (mill finish)

· Hot-dipped galvanized coating per ASTM A53

· Custom primer coatings available

Galvanizing Process: Hot-dipped zinc coating provides corrosion resistance for outdoor applications. Coating thickness meets ASTM A53 requirements.

Quality Control

Multi-Stage Inspection:

At JS FITTINGS, we understand that the integrity of an ERW pipe lies in its weld seam. Beyond the required 100% Hydrostatic Testing, we employ Online Ultrasonic (UT) Weld Inspection and post-weld Seam Annealing to ensure the welded area is as strong and ductile as the base metal. Each pipe is stenciled with a unique heat number for 100% material traceability back to the original steel coil.

Customer Reviews

"We tested the pipes and their performance is very nice. We will make the new purchase plan for the warehouse."

We've sourced ASTM A53B ERW pipes from several suppliers, but JS FITTINGS stands out for their dimensional accuracy. The concentricity was perfect, which significantly reduced our welding time on-site. The black coating was also very durable during transit."I am thoroughly impressed with the quality of the fittings provided by JS FITTINGS. Each piece displays excellent finish and precision, ensuring a perfect fit every time."

"Their efficient production and fast delivery times are remarkable. JS FITTINGS completed our large order ahead of schedule, keeping our project timeline on track."

FAQ

Q: What's the difference between Grade A and Grade B?

A: Grade B offers higher tensile strength (60,000 psi vs 48,000 psi) and yield strength, making it suitable for higher pressure applications.

Q: Can ERW pipes handle the same pressure as seamless pipes?

A: Yes, when properly manufactured and heat-treated, ERW pipes meet the same pressure ratings as seamless pipes per ASTM A53.

Q: What welding procedures work best with these pipes?

A: Standard welding procedures for carbon steel apply. Preheating may be required for thicker walls or low-temperature service.

Q: How do you ensure weld quality?

A: Each weld seam undergoes heat treatment at minimum 1000°F and passes flattening tests to verify ductility.
