Seamless elbow manufacturers produce seamless elbow, straight seam elbow, butt welding elbow, elbow pipe products of various angles and materials, sufficient supply, support each customer to the company to buy, affordable, a variety of kinds of pipe products for you to choose, choose the company to order pipe products advantage is to support online ordering.
The raw material of seamless elbow pipe fittings is round tube billet, and the round tube embryo is cut and processed by the cutting machine to the billet with a length of about one meter, and sent to the furnace by the conveyor belt for heating. The billet is fed into the furnace and heated to a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in the furnace is a critical issue. After the round tube billet comes out, it should be perforated by the pressure punch. Generally more common piercing machine is the conical roller piercing machine, this kind of piercing machine has high production efficiency, good product quality, large perforation diameter expansion, can wear a variety of pipe fittings. After perforation, the circular tube billet is successively three - roll oblique rolling, continuous rolling or extrusion. After extrusion, the diameter should be taken out of the pipe. The sizing machine rolls steel blanks through a cone bit at high speed to punch holes and form pipe fittings.
Seamless elbows are free from corrosion, pitting, rust or wear. Stainless steel is still one of the materials with higher strength in building metal materials. Because stainless steel has good corrosion resistance, so it can make structural components will maintain the integrity of the engineering design. The raw material of rolling seamless elbow pipe fittings is round tube blank. The blank of round tube should be cut and processed by the cutting machine, and the length of the blank is about one meter, and sent to the furnace by the conveyor belt for heating. The billet is fed into the furnace and heated to a temperature of about 1200 degrees Celsius. Temperature control in the furnace is a critical issue.
