Advantages of Stainless Steel Pipe Fitting



In the future, China’s stainless steel pipe fitting market will have rapid growth and development in many fields. This is the current development trend. There is no doubt that as an enterprise, how to deal with the development, while doing a good job in quality management of stainless steel materials, forming process, wall thickness change and solution (heat treatment) and other quality management, it is also necessary to do a good job in the implementation and guidance of product quality and technical specifications, so that more users It is a systematic project to understand the function, use, and maintenance of the products, accelerate the popularization of stainless steel water supply pipe fittings and increase the market share, and promote the application of stainless steel pipe fittings in various fields. It also needs the cooperation and efforts of all links and all aspects.


1.Wall thickness of stainless steel pipe fittings
From the perspective of safety factors and economy, we suggest that the wall thickness of Series II specified in GB∕T 12459-2017 should be selected for dn15-dn50 stainless steel pipe fitting, and series I specified in GB∕T 12459-2017 should be selected for dn65-dn100 stainless steel pipe fitting, which is the best choice for thick wall stainless steel pipe.


2.Protection after installation and use
Stainless steel has very good corrosion resistance. When stainless steel products are placed in micro acid and micro alkali environment for a long time, stainless steel will also be corroded. This kind of corrosion not only corrodes the appearance of stainless steel products but also corrodes the intergranular structure of stainless steel products. Secondly, a high humidity environment also produces corrosion to stainless steel. If stainless steel is in a high humidity environment for a long time, it will also cause corrosion to stainless steel products. Third, in the dust environment will also cause product corrosion, reducing the service life of stainless steel pipe fittings.


3. Pay attention to water for pipe fitting pressing test
Clean tap water must be used for pressure test. It is strictly prohibited to use engineering sewage or unclean river water, well water or groundwater, which will cause corrosion of stainless steel pipe fittings.


4.Cost and cost performance.
The one-time investment cost of stainless steel pipe fitting is about twice that of common galvanized pipe, about 50% higher than that of PPR composite pipe fitting. But if the whole life cycle cost of the building is taken into account, the average cost advantage of stainless steel pipe fitting is very obvious.

The service life of stainless steel pipe fitting is generally 70 years, the service life of carbon steel pipe fitting is about 10 years, and the cost of replacing the pipeline is much higher than the original investment. Stainless steel pipe fitting is the most suitable pipe for water delivery.
