Thick-walled Stainless Steel Stamping Elbow Manufacturer Process And Welding
The process and welding of the manufacturer of Stainless Steel Weld Elbow is generally a circular ring shell that can be cut into 4 90° elbows or 6 60° elbows or elbows of other specifications. This process is suitable for manufacturing large elbows of any specification with a ratio of the middle diameter of the elbow to the inner diameter of the elbow greater than 1.5. It is currently an ideal method for manufacturing large pressure-bearing elbows. The stamped elbow has good pressure resistance. However, due to various factors, the actual wall thickness of the floor heating pipe is usually, and under this wall thickness, all kinds of pipes can meet the requirements of floor heating, and the advantages of the national standard stamped elbow pipe that is not afraid of pressure are not reflected; thermal conductivity: The pipe used for floor heating needs to have good thermal conductivity, low temperature resistance to thermal shock, and low temperature resistance to shock performance. No pipe blank is required as raw material, which can save the cost of pipe making equipment and molds, and can be any large diameter and relatively thin wall thickness elbow.
Below we will introduce the characteristics of thick-walled stamped elbows in detail:
1. Environmental protection: PE-RT can be recycled and does not pollute the environment. PEX cannot be recycled and will cause secondary pollution; Development trend of stamped elbow pipes: The material of stamped elbows not only has a qualified creep fracture curve, but also has a moderate price. The construction is convenient and easy compared to other types. The connection method belongs to the current standard mutual melting hot melt connection method. The aperture of the pipe fitting is larger than the inner diameter of the same standard pipe. In the system, there is no mechanical connection method of partial reduction, so the system fluid resistance is relatively small.
2. Long-term pressure resistance. From the perspective of stress description, the national standard stamped elbow has good pressure resistance. However, due to various factors, the actual wall thickness of floor heating pipes is generally 2mm. Under this wall thickness, all kinds of pipes can meet the needs of floor heating, and the advantages of stamped elbow pipes are not pressure-resistant;
3. Low temperature heat shock resistance: PE--RT and PEX are better than those of PEX. During winter construction, the pipe is not easily broken by impact, which increases the flexibility of construction organization.
4. Thick-walled stamped elbows have good pressure resistance. However, due to various factors, the actual wall thickness of floor heating pipes is generally , and under this wall thickness, all kinds of pipes can meet the needs of floor heating, and the advantage of stamping elbow pipes not being afraid of pressure cannot be shown; thermal conductivity: pipes used for floor heating need to have good thermal conductivity.
The forming process of thick-walled stamping elbows is complicated, and they need to be welded according to different materials and uses, and gradually formed under the pressure of . The forming of stamping elbows needs to be carried out according to the procedures, and the corresponding process must be strictly followed, otherwise the stamping elbows produced will have quality problems. According to the needs, a circular ring shell can be cut into 4 90° elbows or 6 60° elbows or elbows of other specifications. This process is suitable for manufacturing large-scale push-made elbows of any specifications with a ratio of the middle diameter of the elbow to the inner diameter of the elbow greater than 1.5D. It is an ideal method for manufacturing large push-made elbows. This process forming method is used in the production of different elbows, showing outstanding application value in different areas, so that the process has outstanding value performance in the manufacture of different elbows.
