Can welded elbows be made on site using Large Diameter Carbon Steel Line Pipe?


Large Diameter Welded Carbon Steel Line Pipe can be used for making welded elbows on site.


The main consideration is the Large Diameter Welded Carbon Steel Line Pipe to send the medium, pressure and so on.


Elbow is an elbow that can change the direction of elbow in the piping system. Points according to the Angle 45 ° and 90 ° 180 ° three most commonly used, according to the requirements of the project also includes 60 °, and other abnormal Angle bend. The material of elbow has cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metal and plastic to wait.


The connection with the Large Diameter Welded Carbon Steel Line Pipe is as follows: direct welding (the most common way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection, etc.  According to the production process can be divided into: welding elbow, stamping elbow, push system elbow, casting elbow, welding elbow. Other names: 90 degree bend, right Angle bend, love and bend, etc. Large Diameter Carbon Steel Line Pipe is a strip steel coil as the raw material, Large Diameter Welded Carbon Steel Line Pipe often warm extrusion molding, automatic double wire double submerged arc welding process from the spiral seam steel tube.
