304 stainless steel is an austenitic stainless steel and is in principle a non-magnetic product. However, in actual production and use, it may be found that 304 stainless steel has a certain weak magnetism. This is mainly due to the following factors:1. Phase transformation during processing and for

After welding galvanized square steel pipes, the quality of the weld can be checked by the following methods:1. Visual inspection: First, you can visually inspect whether the surface of the weld is smooth and whether there are cracks, bubbles, holes, and other defects. At the same time, it is also n

There are many requirements for the surface treatment of galvanized steel pipes, as follows:1. Cleanliness: The surface of the steel pipe should be cleaned of oil, dust, oxide scale, welding slag, and other impurities to ensure that the galvanized layer is closely combined with the surface of the st

When we purchase a new cold-rolled square steel pipe product, whether it is used in construction, furniture, or other fields, we hope that it will remain as smooth as new and will not rust. However, the reality is that some cold-rolled square steel pipe products do tend to rust over time. So, will c

Steel pipe piles are widely used in various situations such as support piles and friction piles. Especially when used as support piles, since they can be fully driven into the harder support layer, they can exert the load-bearing effect of the entire cross-sectional strength of the steel. Even in de

1. Caliper method:Use a caliper or tape measure to directly measure the outside diameter of the pipe. Make sure the caliper's jaws are firmly against the pipe surface to get an accurate reading. This method is simple and quick and suitable for most stainless steel pipes.2. Ultrasonic thickness gauge

The reasons for the cracking of stainless steel pipes may be as follows:1. Material quality issues: The quality of the 304 stainless steel pipe is poor or the material does not meet the standards, which may lead to insufficient strength of the pipe, resulting in cracking during use. Non-metallic inc

Stainless steel pipes are widely used for their excellent corrosion resistance. Before answering this question, let us first understand the basic concepts of stainless steel pipes and corrosion.A stainless steel pipe is a metal pipe composed of iron, chromium, nickel, and other alloy elements. The c

The main reasons why argon gas protection is needed when welding 304 stainless steel pipes are as follows:1. Prevent oxidation: Argon is an inert gas and does not easily react chemically with other substances. During the welding process, high temperatures will cause oxidation reactions between iron,

With the rapid development of modern industry and urban construction, steel pipes, as an important building material, have become more and more widely used. Among the many types of steel pipes, internal and external hot-dip galvanized steel pipes 150 have gradually emerged in fields such as construc
