China Factory Supply Equal 1/2 Inch Stainless Steel Threaded Metal Elbow 90 SS316 304

The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

Skills Requirement

1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain side. This requirement is also strict, how thick the side, how much angle and deviation The scope is stipulated. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the steel grade of the pipe fitting and the pipe being connected is the same.

2. All pipe fittings must undergo surface treatment, and the iron oxide scale on the inner and outer surfaces is sprayed off by shot blasting, and then coated with anticorrosive paint. This is for export needs. Moreover, it is also for the convenience of transportation in the country to prevent corrosion and oxidation. This work must be done.

3. It is the requirements for packaging. For small pipe fittings, such as export, it is necessary to make wooden boxes, about 1 cubic meter, and the number of elbows in this box cannot exceed one ton. The standard allows sets, that is, large sets and small sets. But the total weight generally cannot exceed 1 ton. For large items, single packaging is required, such as 24" must be individually packaged. The other is the packaging mark, which must indicate the size, steel number, batch number, manufacturer's trademark, etc.
