Hebei Shengtian Group specializes in producing stainless steel pipe caps

　　In engineering practice, basically, the surface area of stainless steel pipe fitting cap is more than 1.66 times the plane circle area, and then multiplied by the thickness, which can be about the volume of thermal insulation cotton.

　　In this regard, the preloading results of 3/4" Special Stainless Steel Pipe Fitting Cap in the preloading process can be judged, and reasonable loading procedures can be formulated to ensure installation. The first is to connect the pipeline and maintain the sealing performance of the pipeline; the other is to open the stainless steel pipe fitting cap to check the pipeline condition; the last is to facilitate the closure or replacement of a section of pipeline.

　　The reason of deformation in R&D and production of stainless steel pipe fitting cap shows that deformation of middle type head can occur roughly after welding in the process of setting up production. Once the deformation of Y exceeds the allowable value, Y can affect the use. The main reason is the uneven local heating and cooling of stainless steel pipe fitting cap. Due to Y welding, Y medium-sized head is heated to high temperature only in the local area. The closer to the weld, the higher the Y temperature, the larger the expansion.
