What is the influence of metal elements in the production of spiral pipe? Next we will give you an introduction.

The comparative study of different forming methods shows that the edge forming effect of single-radius and double-radius forming method is poor, while the forming method with three-radius W shape is better.

Galvanized steel is generally in the low carbon steel outside a layer of zinc, galvanized layer is generally 20um thick. The melting point of zinc is at 419°C, and the boiling point is about 908°C.

Adopt the power source with vertical external characteristics, and use the positive polarity (welding wire connected to the negative pole) when DC.

LSAW steel pipe is a kind of welded steel pipe. It refers to the steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe.

Nowadays, many spiral pipe manufacturers through the production and processing of spiral pipe in the surface did not meet the standard requirements, but there are still successive spiral pipe. Here are some spiral pipe manufacturers to understand some of the requirements for the surface of the pipe.

Straight seam welded pipe production process is simple, high production efficiency, low cost, faster development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe, and it can produce welded pipe with larger pipe diameter from narrower billet, and it can also produce welded pipe with different pipe diameter from the same width of billet. However, compared with the same length of straight seam pipe, the length of welded seam increases by 30-100%, and the production speed is lower.

In recent years, with the continuous upgrading of the welding process of large diameter spiral steel pipe (SSAW), its processing quality and process performance will be significantly improved. As a result, the quality of the plant will also differ in grade. Among other things, there will be a very big gap in its quality after the increasing variety of such pipes sold on the market. So, what exactly determines it?

Spiral steel pipe is a strip of steel coil as raw material, often temperature extrusion city pressure, according to the spiral shape of the bending molding, automatic double-wire double-sided submerged arc welding process for the inner seam and outer seam welded spiral seam steel pipe. Raw materials, namely strip coil, welding wire, flux.

Spiral steel pipe irrigation system can be categorized into mobile, semi-fixed and fixed according to the working mode.
