Carbon Steel Forged Flange Slip On Weld Neck Pn16 DN 100 Gost 12820
Flanges are used when the piping joint needs dismantling. These are used mainly at equipment’s, valves and specialties. In certain pipelines where maintenance is a regular feature, breakout flanges are provided at definite intervals. A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets and the bolting. Special controls are required in the selection and application of all these elements to attain a leak-proof joint.
