ASTM Carbon Steel/Stainless Steel 90 Degree Elbow

The elbow is formed by pushing through sections of short pipe. Then cut the whole pipe into a section, different caliber elbow feeding length is different, then coated with lead powder, and then set to push the core head of the elbow, the machine starts, the short tube moves forward, to the heating device there, the tube is rapidly heated, at the same time the pipe continues to move forward, and so on through the core head will become a Bend. 90 degree elbow is a connection pipe commonly used in water heating installation. It is used to connect the bend of the pipe and change the direction of the pipe.

Elbow is divided into straight seam and seamless. Straight seam is made of straight seam steel pipe, also called straight seam pipe fittings, sometimes requires grinding welding neck. Seamless steel pipe products are also called seamless pipe fittings. Seamless elbow can be divided into pure seamless and seamless two kinds. Elbow according to the Angle can be divided into 45 degrees elbow, 90 degrees elbow, 180 degrees elbow these three common elbow, and other engineering needs can be customized other angles. According to the radius can be divided into long radius and short radius. We have many large and small elbow moulds to meet your different needs under ASME/ANSI JIN DIN EN GB and other standards.

Elbow materials are cast iron, stainless steel, alloy steel, calcined cast iron, carbon steel, nonferrous metals and plastics. The most commonly used materials are carbon steel and stainless steel. Elbow standard table shows that according to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, etc. Other names: 90 degree bend, right Angle bend, love bend, etc.

We should pay attention to the late maintenance of  Carbon Steel Elbow. Long-term storage elbow, should be checked regularly, often on the exposed processing surface must be kept clean, remove dirt, neatly stored in a ventilated and dry place, strictly prohibited pile or open storage. Long-term storage elbow elbow, should be checked regularly, often on the exposed processing surface must be kept clean, remove dirt, neatly stored in a ventilated and dry place, strictly prohibited pile or open storage. Attention should be paid to the tightness of the elbow during installation to prevent leakage and affect the normal operation of the pipeline. Ball valves, globe valves and gate valves of elbow are only fully opened or fully closed, and are not allowed to be used for regulating flow, so as to avoid erosion of sealing surface and accelerated wear.

Maintenance of Stainless Steel Elbow

1, long-term storage of stainless Steel Elbow need regular inspection, if a long time exposed to the outdoors, should be kept clean and remove dirt, they should be stored in a dry and ventilated clean room, should not be stacked or open storage, because stainless steel elbow should be kept dry and breathable, so it should be stored in accurate storage methods.
