The gray spots of different sizes on the surface of galvanized seamless steel pipes are the color difference of galvanizing, which is a problem in the current galvanizing industry. It is mainly related to the trace elements contained in the steel pipe itself and the components in the zinc bath. The stains do not affect the anti-corrosion performance of the steel pipe, but only differ in appearance. On the surface of each galvanized seamless steel pipe, there are gradually obvious raised marks, which are all zinc. The galvanized seamless steel pipe is taken out of the zinc pot, and the zinc liquid flows down the pipe wall and then cools and solidifies.

The promotion and application of precision seamless pipes is of great significance to saving steel, improving processing efficiency, and reducing processing procedures or equipment investment. It can save costs and processing time, increase output and material utilization, and at the same time help improve product quality, reduce costs, and improve economic benefits. Generally, precision seamless pipes are used in industries with high precision requirements, while seamless pipes are mostly used in industries without precision requirements. After all, the price of precision seamless pipes of the same specifications is higher than that of seamless pipes.

What are the inspection items for American standard seamless pipes? There are many quality inspection items for American seamless steel pipes, mainly including physical and chemical properties, composition detection, size and process performance. This article takes the ASTM A450/A450M standard for steel pipes exported to the American standard as an example. Each requirement in this standard is activated by a total of 34 ASTM steel pipe standards, including ordinary seamless splicing and welded steel pipes, as well as American standard seamless pipes for steam boilers, ironmaking, sanitation, natural gas, and natural gas water supply pipelines. In the standard, each requirement is divided into mandatory and non-mandatory. Non-mandatory requirements are mainly inspected through agreements between supply and demand parties.

American standard seamless pipe is a long steel with a hollow cross-section and no seams on all sides. American seamless steel pipe has a hollow cross-section and can be used as a pipeline for conveying fluids, such as oil, natural gas, coal gas, water and some solid substances. Compared with solid steel such as round steel, American standard seamless pipe has a lighter weight under the same bending and torsional strength. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, steel scaffolding for construction, etc.
