Sanitary pipe fittings are
parts that join pipes into pipes and are made of stainless steel. According to the connection method, it can be divided into welded type, clamp type and threaded connection. It is commonly used in the pharmaceutical, food and other industries, and the fittings used in places with high hygiene requirements. The general procurement is the configuration of the pharmaceutical or food factory for maintenance and related equipment. The purchaser is basically a pharmaceutical, food equipment system integrator and buy wholesale.
However, the deformation of the pipe fittings occasionally occurs during the use of the pipe fittings. There are many reasons for the pipe fittings deformation: firstly, the quality involves raw materials, process equipment, molds, operation processes, etc. At present, the domestic and international markets for injection molding water supply and drainage pipe fittings are large. The quality problem is the stability of the matching size. The inner wall is lacquered with silver thread, the internal stress is cracked, the wall thickness is uneven, the hole is out of round, the pipe joint is difficult to connect, the butt welding overlap area is small, and water leakage is easy.
Many manufacturers use materials that are irregular and usually refer to nickel content. Although it can be distinguished by syrup, it is obviously a misunderstanding, because the small charge contains only more than seven nickels that cannot be distinguished. However, the price difference of raw materials is very large, and this is one of the fakes. In particular, 321 high nickel and 316 high nickel are very serious.
Many customers use calipers to measure the thickness when looking at
Stainless Steel Pipe fittings, but this still ignores the fact that the thickness of the back arc is not enough!!! Because there is a reduction in the wall during the pushing process, the caliber is barely up to standard, and the back is solitary. Basically unqualified, generally experts know that 114X3.5 pipe fittings will use 114X4 thick pipes to produce. If the manufacturer purchases a little thinner, the natural loss will be reduced a lot, but the product will become the above-mentioned illusory, the surface is up to standard.
All fittings should be used and maintained in a correct and reasonable manner so that they can be extended. Today is also bringing valuable experience to the users:
1. Sanitary ball valve, sanitary grade stop valve, when used as sanitary level gate valve, only fully open or fully closed, do not allow to adjust the flow, so as to avoid erosion of the sealing surface and accelerate wear. The gate valve and the upper thread stop valve have an inverted sealing device, and the hand wheel is screwed to the position on the Zui to prevent the medium from leaking from the packing.
2, long-term storage of pipe fittings, should be checked on time, often exposed surface must be kept clean, remove dirt, neatly stored in a place where the air is dry and dry, no stacking or open storage. Always keep the pipe dry and ventilated, keep the cleaner clean and tidy, and store it according to the exact storage method.
3. When installing, the pipe fittings can be directly installed on the pipeline according to the connection mode, and installed according to the used position.
Under normal circumstances, it can be installed at any position of the pipeline, but it is easy to check the operation. Note that the flow direction of the stainless steel elbow should be upward and downward from the longitudinal valve. The stainless steel head can only be installed horizontally. Pipe fittings should pay attention to the sealing when installing, to prevent leakage and affect the normal operation of the pipeline.
Well, the above is the full analysis of the reasons for the deformation of
sanitary pipe fittings and the use and maintenance methods. I hope that the award can help.
