Scour strength of seamless elbow and seamless elbo

Scour strength of seamless elbow and seamless elbow

The seamless elbow and the seamless elbow have different R, which is the position that controls the length of the seamless elbow and the seamless elbow. The scour strength of small R through the medium must be much greater than that of large R, that is to say, the scour strength of 1D seamless elbow is not as good as that of 1.5D seamless elbow. The scour strength of 1.5D seamless elbow is lower than that of seamless elbow, and the scour wear of seamless elbow is greater than that of seamless elbow. There is also a special case, such as bridge class, need to use a long span seamless elbow to cross the past, at this time can not use seamless elbow, the general hot pipe also use seamless elbow.

Seamless bends have different uses in different industries, can be freely extended long distances, have the advantage of bending, and the strength of the building will be reduced. Seamless elbow pipe is widely used in electric power, petroleum, navigation, chemical industry and other fields, mainly used in oil transportation, natural gas transportation, and plays an important role in aircraft and its engine.

What is the manufacturing process of seamless elbow?

Seamless elbow will not occur erosion, pitting, corrosion or wear, because stainless steel has excellent corrosion resistance, so it can make the structural components can 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 cutting machine with a length of about one meter, and sent to furnace for heating by conveyor belt. The billet is sent into the furnace to be heated, the temperature is about 1200 degrees Celsius, the temperature control in the furnace is the main problem, after the round tube billet is released to be pierced by a punch, the fuel is hydrogen or acetylene.
