Good production process creates high-quality stainless steel elbows
So how to improve the production process of stainless steel elbows?
- Use high-quality stainless steel materials
The quality of raw materials in the market is currently uneven. Suppliers of stainless steel pipe fittings must be evaluated and selected. Second, the manufacturer’s quality inspection report is required. Third, check and analyze the materials repurchased by the factory. When you choose to buy from a large steel plant, the cost will be higher, but the quality of the steel is also guaranteed.
- Improve process and control wall thickness
The biggest advantage of extrusion molding is due to the feed that meets the material quality requirements. Therefore, the wall thickness of the “U-shaped groove” in the extrusion process is not reduced. The expansion process has stable processing performance, smooth surface and small springback. Although there are other advantages, there is the disadvantage of thinner tube wall thickness.
Regardless of whether the extrusion process or expansion process is used. Both must ensure the thickness and quality of the pipe wall. In the Chinese domestic market, some stainless steel pipe fittings suppliers always sell very cheap stainless steel pipes to customers. This may sacrifice wall thickness and strength.
- Solid solution is effective for improving the quality of stainless steel pipes
The solid solution process can eliminate the stress and intergranular changes in the production process, which can effectively improve the quality of stainless steel elbows.

In addition, daily maintenance is also very important to the service life of stainless steel elbows!
The one-time investment cost of stainless steel elbow is about twice that of ordinary galvanized steel pipe. It is about 50% higher than PPR and other composite pipes. However, considering the life cycle cost of the building. The average cost advantage of stainless steel pipe is obvious.
The life of stainless steel elbow is generally 70 years, and the life of galvanized pipe is about 10 years. Stainless steel pipe is currently the best fluid pipe.
From a certain perspective, the wall thickness of a stainless steel pipe is proportional to its mass. But for economic reasons, in actual use, the elbow must be selected according to the specific needs of the structure.
Stainless steel has good corrosion resistance. Stainless steel products will be corroded if they are exposed to weak acid and weak alkaline environment for a long time. Long-term exposure of stainless steel to high humidity will also cause corrosion to stainless steel products. Therefore, regular maintenance is required.
