High pressure stainless steel tubing fittings are the most widely used chromium - nickel stainless steel, with outstanding corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion in the atmosphere, and if it is heavily polluted industrial atmosphere or region, demand for timely cleaning to prevent corrosion. Suitable for use in food processing, storage and transport. Outstanding processing capabilities and weldability. Plate heat exchanger, bellows, household goods, building materials, chemical, food industries.
Operational capacity of its high pressure pipe fittings where the stress related to the situation. Accounting and field operations for pipe stress measurement found elbow arc particularly sensitive point in the external load. To get rid of internal pressure and external load weight, etc. mainly in the starting process piping thermal expansion of metal pipes, tubing hanger sensation and abnormal operations and other additional external load caused. When the elbow is a cross-sectional arc butt weld, these changes will form a crater in the external load stress messy situation, severe weakening the weld strength and decrease operational capability elbow, elbow shorten life. To this end, from the depicted think the interface into the straight section butt welded elbow, that is portrayed with a straight segment elbow, it is conducive to weld butt weld quality progress, improvement elbow life.
