Bend Pipe widely used and promoted in different fields and industries, to varying degrees of application and popularization. It is made of the same material of the plate and pipe stamping die stamping elbow into the ring halves, then two half-rings were set right elbow weld forming. Stamping elbow welded need to follow certain procedures for production and processing, general stamping elbow stiffness greater the higher the carbon content, the higher the intensity, but lower ductility. Mainly refers to the mechanical properties of the steel depends on the carbon content, and generally do not add a lot of alloy steel elbow elements: the pipeline system connecting the two nominal diameter pipe the same or different, so make sure the angle of the line turning the tubular member.
China bend pipe category: Press angle points, the most commonly used are 45 °, 90 ° and 180 ° three kinds, according to project needs in addition also includes other non-normal 60 ° angle bend.
Pipe and coupling approach are: direct welding, flanged, threaded coupling socket type coupling, etc. there.
According to the production process can be divided into: welding elbow, pressing elbow, casting elbow. To material classified as: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum and other.
Production methods can be divided into: push the system, pressing, forging, casting and so on.
Manufacturing standards: GB, electricity standard, water standard, American standard, German standard, Japanese standard and so on.
