Special Design for Thermal Expansion Pipe - Spiral steel pipe Large diameter ERW seamless welded spiral – Lu Detail:

Introduction

Spiral steel pipe is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. The reduction of the squeeze roll is adjusted to control the weld gap at 1~ 3mm, and make both ends of the welding joint flush.
