Product Description

The ERW273 high precision full automatic ERW tube mill is designed for manufacturing welded steel pipes with diameters from Φ114mm to Φ273mm and wall thicknesses from 2.0mm to 10.0mm, including square pipes from 60×60mm to 200×200mm.

ERW Tube Mill Process

Uncoils and flattens steel coils into strips
Forms strips into round pipe shape using precision rollers
Welds tubes using high frequency solid state welder
Sizes tubes to precise dimensions
Cuts to specified lengths (6-12m) with ±3mm accuracy

Key Advantages

High precision manufacturing with diameter and roundness error ≤0.08
Incorporates Japanese technology for superior accuracy
Worm gear adjustment system for precise control
3D adjustable scraping system with ±20° rotation capability
Turkish head push square forming for stable, uniform R angles
Nylon damping blocks reduce impact on shafts and bearings
