Concrete Pump Elbow Common specifications

Stamped concrete pump elbow is the first to be used in mass production of seamless concrete pump elbow forming process, at present, in the commonly used concrete pump elbow production has been hot push or other forming process replaced, but in some Specifications of the concrete pump elbow due to the production of a small number of wall thickness is too thick or too thin.

Stamping

Stamped concrete pump elbow is the first to be used in mass production of seamless concrete pump elbow forming process, at present, in the commonly used concrete pump elbow production has been hot push or other forming process replaced, but in some Specifications of the concrete pump elbow due to the production of a small number of wall thickness is too thick or too thin. In the case of

Products are still in use when they are in special requirements. The concrete pump elbow is stamped with a pipe billet equal to the outer diameter of the concrete pump elbow, and is pressed directly in the mold using a press. In the case of

Before the punching, the tube is placed on the lower mold, the inner core and the end die are put into the tube, the mold moves downward to press, and the concrete pump elbow is formed by the outer mold restraint and the inner mold support. In the case of

Compared with the thermal push process, the appearance of the stamping shape quality is not as good as the former; stamping concrete pump elbow in the forming when the outer arc in the stretched state, no other parts of the excess metal compensation, so the arc at the outer wall thickness of about 10 %about. But because it is suitable for single-piece production and low-cost characteristics, so stamping concrete pump elbow process for small batch, thick-walled concrete pump elbow manufacturing.

Stamping concrete pump elbow sub-cold stamping and hot stamping two, usually according to the nature of materials and equipment capacity to choose cold stamping or hot stamping. In the case of

Cold extrusion concrete pump elbow forming process is the use of a dedicated concrete pump elbow forming machine, the tube into the outer mold, the upper and lower die mold, driven by the push rod, the tube along the inner and outer Mold the gap movement to complete the forming process. In the case of

The concrete pump elbow made by the internal and external mold cold extrusion process has beautiful appearance, uniform wall thickness and small dimensional deviation. Therefore, the stainless steel concrete pump elbow, especially the thin-walled stainless steel concrete pump elbow forming is used in this process. This process used by the internal and external mold precision requirements; the thickness of the tube thickness deviation is also more demanding. In the plate with a press made of concrete pump elbow profile half, and then the two sections welded together. This process is generally used for the concrete pump elbow above DN700. classification

1. Material is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon Ge Lek, PVC, PPR, RFPP (reinforced polypropylene) and so on. In the case of

2. The production method can be divided into push, suppression, forging, casting and so on. In the case of

3. To the manufacturing standard can be divided into national standard, electric standard, ship standard, standard, water standard, American Standard concrete pump elbow, German standard, Japanese standard, Russian standard and so on. In the case of
