Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is an important welding method, which has the inherent advantages of stable welding quality, high welding productivity, no arc light and little smoke and so on. Spiral welded pipe is manufactured with a large diameter and can reach more than 3000mm, which is more suitable for large-diameter pipeline transportation and building structures. 3. Straight seam welded steel pipe

We have very large erw pipe production capacity. ERW steel pipes are used for various engineering purposes, including fences, scaffolding, line pipes, etc. The length of the ERW pipe varies from a single random to 120 feet, depending on the capacity of the rolling mill. ERW pipes have square heads or grooves for welding, threaded connections and Victaulic slotting. The surface treatment can be black
Electric Resistance Welded Pipe, ERW Steel Pipes, Electric High-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe.

WHAT ARE ERW/GP/GI/MS PIPES & TUBESTHEIR Sep 16, 2020 · MS Steel Black Pipes and Tubes. Mild Steel Black Pipes is called MS Black Pipe because it is not galvanized and is an ideal product to be welded into pipes, tubes, and other kinds of tubing. It is one of the cheapest metals available in the market and can last up to 100 years if placed in a well-maintained environment.
The biggest difference between ERW pipe and seamless steel pipe is that ERW pipe has welding line, which is the same as welded steel pipe, but seamless black steel pipe doesnt have, either does the welded steel pipe. Furthermore, the welding line of ERW pipe is the key to the quality of ERW steel pipe. The more unrecognizable the welding line of ERW pipe is, the higher quality ERW pipe has. There are two ways to eliminate the welding
