The spiral steel pipe feeds the strip into the welded pipe unit. After rolling by multiple rollers, the strip is gradually rolled up to form a circular tube blank with an opening gap. 3mm, and make both ends of the welding joint flush.1. If the gap is too large, the proximity effect will be reduced,

The connection of building pipelines is often an operation method that is often required in buildings. What are the methods for building pipelines? Let's see together next.1. Threaded connection. The threaded connection is to use threaded pipe fittings to connect, and galvanized steel pipes with a p

Spiral steel pipe is made of strip steel through the coiling machine, bending in a spiral direction, and then double-sided submerged arc welding by a capacitor. In the production process of spiral steel pipe welding, many galvanized channel steel situations such as missing welding and misalignment a
