The technical requirements for stainless steel elbows are as follows:
Due to the fact that most pipe fittings are used for welding, in order to improve welding quality, the ends are beveled, with corresponding angles and edges. This requirement is also quite strict, with regulations on how thick the edges are, what the angle is, and the deviation range.
2. Requirements for packaging: For small pipe fittings, such as exports, wooden boxes with a capacity of approximately 1 cubic meter are required. It is stipulated that the number of bends in such boxes should not exceed one ton, and this standard allows for a set, with larger sets being smaller.
3. All pipe fittings must undergo surface treatment, with the oxide scale on the inner and outer surfaces sprayed off by shot blasting, and then coated with anti-corrosion paint. This is for export needs, and in addition, it is necessary to do this work domestically to facilitate transportation and prevent rust and oxidation.
Stainless steel elbows have very low heat loss and can effectively save our energy. Once we install it correctly, the entire service life of this pipeline can reach fifty years, which can be considered very good.
