ASTM A134 Electric-Fusion Arc-Welded Steel Pipe for Structural Applications

ASTM A134 electric-fusion arc-welded steel pipe is a large-diameter welded pipe solution for structural applications requiring stable roundness, controlled wall thickness, reliable weld integrity, and flexible dimensional customization. ASTM A134 covers straight-seam or spiral-seam electric-fusion arc-welded steel pipe in NPS 16 and larger sizes, normally with wall thickness up to 3/4 in. [19 mm], while other dimensions may be supplied when they meet the remaining specification requirements. The steel grade is selected according to the ASTM plate specification ordered by the purchaser, making ASTM A134 suitable for structural columns, pipe piles, bridge structures, marine structures, heavy equipment frames, and large fabricated steel assemblies.

Specifications

Item	Description
Material	Carbon steel plate / low-alloy structural steel plate
Standard	ASTM A134 / A134M
Common Grades	ASTM A36, ASTM A283 Grade C, ASTM A285 Grade C, ASTM A572 Grade 50, ASTM A516 Grade 70
Manufacturing Method	Electric-fusion arc-welded, straight seam or spiral seam
Outside Diameter	NPS 16 and above; commonly 406.4 mm and larger
Wall Thickness	Up to 19 mm under ASTM A134 scope; other thicknesses by agreement if compliant
Length	1–12 m, custom fixed length available
Tolerance Range	According to ASTM A134 / project drawing / purchase order
Straightness	Controlled for structural fit-up; project-specific straightness tolerance available
Surface Condition	Bare, black, shot-blasted, primer-coated, anti-corrosion coated, or galvanized by agreement
Heat Treatment	As-welded normally; stress relieving or other heat treatment by agreement when required
Inspection	Visual inspection, dimensional inspection, weld inspection, hydrostatic test or NDT by agreement
Application Positioning	Large-diameter structural steel pipe requiring weld reliability and dimensional consistency

Key Features

Large-diameter capability
ASTM A134 is intended for electric-fusion arc-welded steel pipe of NPS 16 and larger, making it suitable for large structural members where seamless pipe is not economical or dimensionally practical.
Controlled wall thickness range
The standard scope covers wall thickness up to 3/4 in. [19 mm]. Other dimensions can be supplied when agreed and when the pipe complies with the remaining ASTM A134 requirements.
Flexible grade selection
ASTM A134 does not define one fixed steel grade. The final grade is based on the ordered ASTM plate specification, allowing buyers to select A36 for general structures, A572 Grade 50 for higher yield strength, or other plate grades for specific structural or fabrication needs.
Straight-seam or spiral-seam production
The pipe can be manufactured with straight seam or spiral seam welding, allowing different production routes depending on diameter, wall thickness, order quantity, and structural design requirements.
Weld-focused structural reliability
Electric-fusion arc welding provides a full-length welded joint suitable for large structural pipe. For critical projects, weld quality can be verified by ultrasonic testing, radiographic testing, magnetic particle testing, or hydrostatic testing according to the purchase specification.

Our Advantages

Procurement Concern	Practical Risk	Our Solution
Grade selection is often unclear because ASTM A134 is a pipe manufacturing standard, not a single-grade material standard.	The wrong plate grade may lead to insufficient yield strength, poor weldability, or non-compliance with project drawings.	We confirm the design requirement first, then match the pipe with suitable plate grades such as A36, A283 Grade C, A572 Grade 50, A285 Grade C, or A516 Grade 70, with MTC traceability to the ordered plate standard.
Large-diameter welded pipe may show weld misalignment, uneven reinforcement, or poor fit-up.	Poor weld geometry can create fabrication problems during pile splicing, column connection, or structural assembly.	We control edge preparation, forming accuracy, welding parameters, weld appearance, and final dimensional inspection before shipment. NDT can be added according to the project requirement.
Structural pipe buyers often need coating, fixed length, beveling, and documentation in one order.	Multiple suppliers increase coordination time and increase the chance of dimensional or document mismatch.	We can supply pipe cutting, beveling, shot blasting, primer coating, anti-corrosion coating, marking, packing, and inspection documents under one controlled production workflow.
