Swage Nipple is a pipe fitting used for connecting two pipes of different sizes in a straight line to achieve pipe-diameter variation. It is divided into concentric and eccentric pitches. The center line of the two pipes connected by Concentric swage nipple is in a straight line and is mainly used for vertical piping. Eccentric swage nipple is more used in horizontal piping. In small diameter pipelines (below DN50), Swaged nipple is often used instead of joint with different diameter for pipe diameter reduction. Its connection form is different from that of butt welding and threading. It is mainly used in petrochemical, medical and health, electric power, aerospace, military, fire control, metallurgy, shipbuilding, gas, nuclear power, environmental protection, etc. departments and fields requiring high pressure and precise size. The standard of short diameter section refers to American Standard MSS SP-95. The production materials can be Carbon Steel, Alloy Steel, Stainless Steel, Duplex Stainless Steel.
304 Stainless Steel is a grade of ASTM A403 standard. 304 is a versatile stainless steel widely used in equipment and components requiring good comprehensive properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and 8% nickel.
