What are the key details to pay attention to during the welding process of galvanized steel pipes
03-09

First, the welding details for galvanized steel pipes include:1. Galvanized steel pipes with a diameter greater than 100mm should be connected using flanges or compression fittings.2. To ensure welding quality, the weld joint should be treated with galvanizing. The galvanized layer should be cleaned

What are the four methods for measuring the length of spiral welded steel pipes
03-06

Accurately measuring the length of spiral steel pipes is crucial for manufacturers. Based on years of production experience, four methods for length measurement have been summarized:1. Improved Encoder Length Measurement: This is an indirect measurement method. The length of the spiral steel pipe is

What are the quenching technologies for straight seam welded pipes
03-05

Surface quenching and tempering heat treatment for straight seam welded pipes is typically performed using induction heating or flame heating. The main technical parameters are surface hardness, localized hardness, and effective hardened layer depth. Hardness testing can be done using a Vickers hard

Is broaching suitable for the appropriate precision requirements of seamless steel pipes
03-04

In the high-precision machining of seamless steel pipes, broaching is a highly efficient and precise processing method. It's like using a "custom mold" to "shape and polish" the steel pipe, achieving good surface quality and dimensional accuracy in a single process. However, many people are unclear
