Engineering technical requirements for 304 Stainless Steel Elbow

The 304 Stainless Steel Elbow is widely used in industries such as petroleum, chemical, nuclear power plants, food manufacturing and construction and is used in various industries and shows value in various industries. The main difference between 304 Stainless Steel Elbow and Carbon Steel Elbow is the difference in material. The chemical composition prevents the surface of the elbow from rusting and corroding for a long time.

304 Stainless Steel Elbow

1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, leaving a certain angle and with a certain edge. This requirement is also relatively strict, how thick the edge is, the angle and deviation The scope is specified. The surface quality and mechanical properties are basically the same as the tube. For welding convenience, the 304 Stainless Steel Elbow is the same steel grade as the pipe being joined.
2. That is, all 304 Stainless Steel Elbow must be surface treated, the iron oxide scale on the inner and outer surfaces is sprayed off by shot peening, and then painted with anti-corrosion paint. This is for export needs, and in China, it is also to facilitate transportation and prevent rust and oxidation. Work in this area must be done.
3. It is the requirement for packaging. For small pipe fittings, such as export, it needs to be a wooden box, about 1 cubic meter. It is stipulated that the number of elbows in this box should not exceed about one ton. This standard allows sets, that is, large sets are small, However, the total weight should generally not exceed 1 ton. For large pieces of 304 Stainless Steel Elbow, it needs to be packaged in a single package, such as 24″, it needs to be packaged in a single package. The other is the package mark, which should indicate the size, steel number, batch number, manufacturer’s trademark, etc.
