With the development of society, nowadays stainless steel push in fittings are suitable for media such as gas, water, oil, and some corrosive liquids, and it is a kind of pipe fitting that can be quickly disassembled without tools. Lightweight, easy to use, and clean, these fittings are widely used in hydraulic, pneumatic, and lubricating fluid transfer piping systems, especially in situations where frequent disassembly and installation of piping is urgently needed. So how do we ensure the quality of stainless steel push in fittings when we are in the engineering construction process?

(1) The thickness of the fittings is not uniform.

The uneven wall thickness of pipe fittings is critical to producing in the parts of the pipe fittings deformation is very large. Standard stainless steel push-in joint bend back wall thickness is thicker than other parts, and the thickness of the branch pipe and pipe fittings body is not uniform. For such cases of inspection, with the general vernier calipers and other measuring instruments often difficult to detect, the standard stainless steel push-in joint can only be measured by the application of an ultrasonic coating thickness gauge.

(2) Strength beyond the standard.

Standard stainless steel push in fittings strength beyond the standard situation, mainly because the joint after forming the heat treatment process problems, its treatment is to use the appropriate heat treatment process to carry out another heat treatment process, this problem can generally be dealt with.

(3) raw materials and production process caused by the defects of the buckle-type pipe joints in Shandong.

This type of problem is more harmful to the equipment. Check the hydraulic quick coupling and more inconvenient. The elements that cause defects in standard stainless steel push in fittings are more and more complex, and it has both the defects of the raw materials themselves and factors such as production and processing, production and processing process problems, and errors in the heat treatment process.

For such problems, usually with eddy or ultrasonic ferry flaw detection (uT), if strictly following the standard to test, the quality of the pipe can ensure. However, sometimes it is inevitable that leakage and mis-inspection occur, so for the delivery of the pipe, especially the raw materials purchased immediately from the steel pipe factory in large quantities, not only should all reviews be carried out according to the standard, but also the proportion of the review should be increased, and even each root should be checked.

The above is about the engineering construction process to ensure the quality of stainless steel push in fittings. If you need more detailed information, welcome to contact us!
