What are the technical requirements of the elbow?

We all know that elbow is widely used in pipeline engineering, but the production and processing process of elbow is not so easy. There are relevant technical requirements for elbow processing. Now Haihao will show you these technical requirements.

Since most pipe fittings are used for welding, in order to improve the welding quality of elbows, the ends will be beveled. The thickness of the edge of the bevel, the angle and the deviation range are specified.

Any pipe fittings, including elbows, shall be subject to surface treatment. The oxide scale on the internal and external surfaces shall be shot blasted off and then coated with anti-corrosion paint for export; Moreover, in order to facilitate transportation and prevent corrosion and oxidation, this work should be done at home.

Understand the requirements of packaging on the number and weight of elbows. Because the size of ordinary elbow is generally 450 * 450pix, while the size of larger elbow is 630 * 500pix, of course, Haihao Group can also produce corresponding elbow size according to the specific requirements of customers. Although the sizes of elbows are different, they all need to be packed in wooden packing boxes. It is stipulated that if the number of elbows in such boxes is large, the total weight of elbows should generally not exceed 1t. For the packaging of large elbows, a single package is required. Therefore, in the production and processing of elbows, packaging factors should also be taken into account.

After the elbow production and processing inspection is completed, it needs to be marked, that is, the elbow size, steel number, batch number, manufacturer’s trademark, etc. should be marked on the elbow packaging box, so as to facilitate transportation and customer inspection. The above are the technical requirements for the production and processing of elbows. Today, Haihao Group has just finished production of a new batch of elbows. We have advanced production equipment and professional skilled workers. In addition to elbows, Haihao specializes in the production of flanges, steel pipes, pipe fittings and other products.
