Push the characteristics of the elbow

Push the elbow needs normalizing + tempering heat treatment, machining port, wall thickness need to leave burning loss and processing allowance, general allowance is 10%-20% of the theoretical wall thickness of the elbow.The smaller the ratio of the wall thickness of the elbow to the section diameter D, the better the fitting performance with the mold. The push-made elbow, the pressing elbow and the hot-pressed elbow, but the inner arc of the elbow is more likely to be unstable and wrinkled.According to the metal in the plastic deformation volume unchanged, push made into the shape of the wall thickness unchanged actual bit thinning, push the elbow.By pressing the elbow, the outer arc length of the elbow is equal to the length of the pipe billet, and the formula of the outer diameter of the pipe billet is deduced.

The company briefly introduces the push elbow: push elbow shell material, carbon steel, stainless steel, alloy steel, push elbow applicable medium: gas, liquid, steam, push elbow product parameters:Product technology standard and quality control, feeding, the physical and chemical materials -- -- -- -- hot forging forming, heat treatment - inspection processing -- -- -- -- -- -- -- -- finished goods inspection, identification, finished goods inspection, identification, packaging type, in the shipment.

The company can according to the needs of customers to push various angles of the elbow.

The basic process of carbon steel elbow is to weld a polymorphic polygonal annular shell or polygonal fang-shaped shell at both ends. After filling the internal pressure medium, the internal pressure is applied. Under the action of internal pressure, the cross-section of polygons gradually becomes a circle, and finally becomes a circular annular shell.A circular shell can be cut into 4 90 degree elbows or 6 60 degree elbows or other specifications depending on the requirements.This process is suitable for any large elbow with the ratio of middle diameter to inner diameter of elbow greater than 1.5, and it is an ideal way to manufacture large carbon steel elbow.

The advantages of the manufacturing process of carbon steel elbow are as follows: there is no need for pipe billet as raw material, the cost of machine mould for pipe making equipment can be saved, and the carbon steel elbow with arbitrary large diameter and relatively thin wall thickness can be obtained.The blank is flat or exhibition area surface, so the blanking is simple, the precision is easy to guarantee, and the assembly and welding are convenient.Due to the above brief introduction of steel elbow objectives, can shorten the manufacturing cycle, consumption cost is greatly reduced.Because it does not require any common equipment, it is especially suitable for field processing of
