The pressure resistance of elbow Fittings is best resistant to temperature, pressure, flexibility and heat, and its performance is higher than Other plastic pipes. Easy installation and good thermal conductivity for floor heating systems, recyclability. Elbow fittings have excellent impact strength, hot melt welding and mechanical joining, which is superior to the thermal conductivity of PB-PP-R. Long-term pressure resistance, only the design stress, the elbow pipe fittings have the best pressure resistance. However, due to various factors, the actual wall thickness of the floor heating pipe is usually 2 mm. Under this wall thickness, all kinds of pipes can meet the requirements of floor heating, and the pressure resistance of elbow pipe fittings can not be reflected; only the design stress, the elbow pipe fittings have the best pressure resistance performance.
The material of the elbow fittings is special, showing different use values ​​in a certain field, and affecting the development of other industries to some extent. The above is a production method of elbows with a seamless steel pipe as a raw material below 24 inches. After more than 24 inches, that is, 600 mm or more, the maximum elbow is between 2.032 m and 2.80 m, which is made of steel plate. After the steel plate is cut into the required material, it is shaped like UOE, and is punched into a circular shape by punching. There are two halves and then put together and welded. After the push, the elbow should be shaped in this hot state.
After the shape is good, the outer diameter and wall thickness of the elbow pipe fittings have met the requirements. Next, the finishing process is carried out, and after the shot peening, the scale of the inner and outer surfaces of the elbow pipe is removed, and the both ends are treated with a groove to facilitate welding. After inspection, steel printing, painting, packaging and other processes, you can leave the factory. Elbow pipe fitting materials can be classified into different types according to different classification standards. Since we have separately used electronic information materials as a new type of material, the new wear-resistant materials referred to here are mainly other than electronic information materials. Abrasion resistant material. The materials used in elbow fittings are a large class of new materials with special electrical, acoustic, thermal, mechanical, chemical and biological functions. They are important basic materials for high-tech fields such as biotechnology and energy technology, as well as for national defense construction. Some traditional industries, such as agriculture, chemicals, and building materials, play an important role.
There are two more steps in elbow fittings: one is flaw detection and the other is heat treatment. The other programs are the same. There are many kinds of stamping elbow materials, and their applications are widely used. It is forming a large-scale high-tech industrial cluster with a very broad market prospect and extremely important strategic significance. However, due to various factors, the actual wall thickness of the floor heating pipe is usually such that under this wall thickness, all kinds of pipes can meet the requirements of floor heating, and the pressure resistance of the national standard stamping elbow pipe is not reflected; thermal conductivity: The pipe for floor heating needs good thermal conductivity, low temperature thermal shock resistance and low temperature impact resistance. Because some elbows are handled improperly, they will be distorted, which is not allowed. In addition, after the head is pushed, the outer diameter of the front end is generally large, and it is shaped by a shaping die. Due to the presence of welds, non-destructive testing is required. Heat treatment is also required due to the presence of welding stress. Http://
