Large diameter carbon steel elbow manufacturer

Large diameter carbon steel elbow manufacturer  

Large diameter seamless elbow pipe fittings are mainly manufacturers direct sales, quality assurance, low price, not easy to deformation, long service life and other advantages.  

Classification of large diameter seamless elbow pipe fittings:  

Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PPC etc.  

Production methods can be divided into pushing, pressing, forging, casting and so on.  

According to the manufacturing standard, it can be divided into GB standard, electric standard, water standard, American standard, German standard, Japanese standard and Russian standard  

The difference between large diameter seamless elbow and elbow:  

Elbow means elbow (or other pipe fitting) of all materials and methods of manufacture, of all forms of connection, of all pressure classes, including pressed elbow.  

Seamless elbow generally adopts seamless pipe, high pressure grade, butt welding connection.  

Commonly used seamless stamping elbows are made of maleiron (adjustable cast iron), which is almost stronger than steel than wrought iron.  Its purpose is common civil water supply and drainage, the interface can only be threaded connection, pressure grade is less than 10KG or 1MPa, generally 7KG.  

Large diameter seamless elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, suitable for mass production, so it has become the main forming method of alloy steel, carbon steel elbow, and also used in the forming of some specifications of stainless steel elbow.  

Large diameter seamless elbow manufacturers in addition to the commonly used forming process, seamless elbow forming and the use of the tube blank extrusion to the outer die, and then through the tube blank through the ball correction of the forming process.  However, this process is relatively complex, difficult to operate, and the forming quality is not as good as the foregoing process, so it is seldom used.
