114Elbow manufacturers  

Hebei elbow manufacturers mainly produce different types and materials of elbow, head, tee, pipe cap, flange and other pipe fittings.  The above pipe fittings are mainly used for pipeline installation.  Main material: carbon steel, alloy steel, stainless steel and so on.  Production standards are divided into GB, German standard, Italian standard, American standard, Russian standard, etc.  

The manufacturing process of elbow fittings is mainly in the pipeline system. The elbow is a pipe fitting that changes the direction of the pipeline.  According to the Angle, there are three kinds of 45° and 90°180° commonly used, in addition according to the engineering needs also include 60° and other abnormal Angle elbow.  Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics, etc.  

The ways to connect the pipe are: direct welding (common way) flange connection, hot melt connection, electric melt connection, thread connection and socket type connection.  According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow and so on.  Other names: 90 degree bend, right Angle bend, etc.  

Elbow manufacturer technical requirements: Because most of the pipe fittings are used for welding, in order to improve the welding quality, the end of the car into a bevel, leave a certain Angle, with a certain edge, this requirement is also more strict, how thick the edge, how much Angle and the range of deviation are specified.  The surface quality and mechanical properties are basically the same as pipes.  For the convenience of welding, the pipe fittings are of the same steel grade as the pipe to be connected.  

That is, all pipe fittings should be surface treated, and the oxide iron on the inner and outer surfaces should be sprayed off by shot peening, and then coated with anti-corrosion paint.  This is for export needs, moreover, in order to facilitate transportation to prevent corrosion and oxidation, are to do this work.  

It is to the requirement of packaging for small pipe fittings, such as export, need to do wooden cases, about 1 cubic meter, the number of elbow in the box can not exceed about a ton, the standard allows suit, that is, a large set of small, but the total weight generally can not exceed 1 ton.  For large pieces, you need to pack them individually, like 24 ".  Another is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer, etc.
