How to improve the quality control of stainless steel pipe fittings?

Stainless steel water pipes have a long service life. Judging from the use of stainless steel pipes abroad, the service life of stainless steel water pipes can reach 100 years, at least 70 years, the same life as buildings. The most prominent advantage of stainless steel pipe fittings is corrosion resistance. If stainless steel pipes are used and maintained correctly during use, they can effectively extend their service life. Today we mainly introduce the quality control and improvement of stainless steel pipe fittings.

1. Control the quality of stainless steel materials in procurement

In the current market, there are phenomena such as raw materials with different quality, so we should strictly control the quality of raw materials in procurement. First, the supplier must be evaluated and selected, and the evaluation report and quality records should be established. The procurement information should be clear and complete. Second, there must be quality inspection report of manufacturers. Third, the materials purchased and returned to the factory should be tested and analyzed. It is recommended to go to a large steel mill to buy the material.

2. Adopt reasonable process and technical measures to control the wall thickness of pipe fittings

The biggest advantage of extrusion molding is that the wall thickness of "U-groove" and "three-way pull-out" is not thinned by replenishment during the extrusion process, and the product quality requirements are met. The advantage of the bulging process is that the processing performance is stable, the surface is smooth and the rebound is small, and the disadvantage is that the wall thickness of the pipe is thinned.

No matter what process is used, it is the premise to ensure the thickness of the pipe wall and the quality, and it is also a specific embodiment of the company's cost, quality and technical requirements. There are often manufacturers selling too cheap stainless steel water pipes to customers. Most of them sacrifice the wall thickness and strength of the pipe, which poses hidden dangers to the connection of thin-walled stainless steel pipes.

3. Solid solution is an indispensable process to improve the quality of pipe fittings

The solid solution process can eliminate the stress and intergranular changes in the production process. Everyone knows that although the cost of solid solution process will increase between 2600-2800 yuan per ton, it is an important measure to improve the corrosion resistance. Solid solution should be carried out after the pipe forming process is completed, it can really play a protective role and cannot be omitted.

In the future, China's stainless steel pipeline market will have a rapid growth and develop in many fields. This is the current development trend. As an enterprise, while doing a good job in quality management of stainless steel materials, molding processes, wall thickness changes, and solid solution, it is also necessary to implement and guide product quality and technical specifications, so that users can understand more about the functions, use and maintain, accelerating the popularization of stainless steel water supply pipelines and increasing market share, and promoting the application of stainless steel pipes in many fields. This is a systematic project, and it also needs the cooperation and efforts of all links and all aspects. 

With the rapid market development of stainless steel pipes, the demand for stainless steel pipe fittings will also increase, therefore, we should pay more attention to the improvement of pipe fittings, which can in turn improve our market influence and share.
