 straight seam steel pipe bending process


Elbow bending, straight seam welded pipe mold is used to bend the sleeve, no matter what kind of equipment, mainly for pipe, mainly for oil and gas, and other fluids in the aircraft and engines have an important position. Elbow bend profiles of various profiles, almost all sections of aluminum, steel, stainless steel, copper and other metal profiles, pipe (spiral, straight seam steel, seamless steel pipe) can be bent. High-quality elbow, through painting, plating, polishing, drawing and other materials can be bent, will not damage the surface of the material.


Reduce the elbow material: cast iron, stainless steel, alloy steel, malleable iron, steel, non-ferrous metals and plastics. Fittings: Direct welding (the most common method) flange welding joints, hot melt connection, threaded connection, socket coupling.

The steel pipe pile is suitable for terminal construction. The diameter range is generally between 400-2000mm, and the most commonly used is 1800mm.


The special-shaped steel pipe can better adapt to the special use conditions, save metal and improve the productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing. The methods of producing special-shaped tubes include cold drawing, welding, extrusion, hot rolling, etc. cold drawing method has been applied more and more widely. The utility model is curved or circular when the steel pipe piles are used between cofferdams. It can play the role of water, soil, sand and so on. The utility model has the advantages of novel design, simple structure, convenient operation, easy overlap and good sealing performance. It includes cross section non-circular, other wall thickness, variable wall thickness, variable diameter and variable wall thickness, cross section symmetry and asymmetry. Such as square, rectangular, conical, trapezoidal, spiral pipes, etc.


The steel pipe pile is opened by the steel pipe, the mouth and the mouth, and the vertical tube wall of the pipe diameter is connected with the mouth part. The cross section of the mouth is the square frame of the opening. It has the side of the wall of the reinforcing part, the diameter of the right side of the tube wall and the vertical position of the vertical connection of the mouth, and the groove mouth is I shaped.
