Shrimp back elbow _ Hebei Guotai most professional _ drawing processing shrimp back elbow provided by Hebei Cathay. Shrimp back elbow, Hebei Guotai most professional, mounds shrimp back elbow manufacturer Hebei Cathay Pacific Pipeline Equipment Co. (www.hbgtgd.com) 2014 upgrade been newly launched professional production flange, elbow pipe fittings, and sales agents reducers, flanges, pipe caps, manholes, pipe fittings, etc., at the lowest price, high quality products to win the majority of customers will not produce stainless steel elbow corrosion, pitting, corrosion or wear. Increase the corrosion resistance of stainless steel with a carbon content of stainless steel reduces the elbow, so most of the lower carbon steel elbow volume, which is the main alloying elements Cr, when the Cr content is only up to a certain value shrimp waist Elbow materials are guaranteed only the corrosion resistance of stainless steel elbow. Elbow to divide the material of carbon steel, cast steel, alloy steel, stainless steel, copper sheet processing shrimp back elbow, aluminum, plastic, argon Ge Lek, PVC, PPR and so on. 2 in production methods can be divided into pushing, pressing, forging, casting and so on. 3 to manufacturing standards can be divided into GB, electricity, water standard, American standard, German standard, Japanese standard, Russia and other standard. 4 by its radius of curvature of points: can be divided into long radius elbows and short radius elbows. It refers to a long radius bend radius of curvature is equal to 1.5 times the outer diameter of the tube, i.e., R = 1.5D. Short radius elbow refers to its radius of curvature equal to the outside diameter of the pipe elbow Hebei Cathay waist shrimp production, namely R = 1.0D. (D is the diameter of the bend, R is the radius of curvature). 5, if the pressing force levels to point: about seventeen, and the United States is the same as the standard tube.
