Overview:
We produce 180 degree elbows as per ASTM, JIS and DIN standards. and in carbon steel alloy steel, stainless steel, super austenitic duplex, super duplex, nickel alloys, ttanium, titanium composite and aluminum, etc. Elbow are widely used in oil &r gas, petrochemicat refineries, power plant, shipbuilding metallurgy, paper making and other industries.meanwhile,180 Degree steel elbow helps change direction at 180 degrees, since it usually results in low pressure. Its application is limited to minimal deposition and low turbulence system.
