Alloy tee

Alloy three pass is mainly used in the pipeline installation of a connecting pipe, used for the connection of the bend of the pipe. Connect two tubes with the same nominal diameter to make the pipe bend at 90 degrees or other angles. Three alloy is a kind of variety referred to the elbow, it made a variety of common carbon steel, manganese steel, nickel steel etc.. Alloy three pass is very widely used. The common bronze alloy three pass is more common in the general tap water pipe, but with the improvement of living standards, many water pipes are converted to stainless steel elbow. The three-way steel has excellent performance due to shock, extrusion, the alloy steel material wear material, are usually used in concrete pipes, mud pipes wear serious in pipeline. The three general high manganese steel alloy is used in fluid flow is more intense, the impact is relatively strong in the pipeline; the three nickel steel alloy material is usually used in high concentration oxidizing acid (nitric acid, sulfuric acid etc.) at room temperature pipeline, but in reducing acid (hydrochloric acid, sulfuric acid and so on) of the transmission pipeline is will be severely corroded, unless the concentration of hydrochloric acid is very low; the ability of martensitic alloy high temperature strength, three at 650 DEG C has high oxidation resistance and corrosion resistance to water vapor, but poor weldability. Therefore, it is often used in high temperature steam transportation pipeline and water gas pipeline. Implementation standards: GB/T12459-2005, GB/T13401, GB/T10752-1999.

Alloy three pass: beautiful appearance, smooth and smooth surface, acid and alkali resistance, high temperature, reasonable price calculation, beautiful appearance, strong texture performance.

Applications: widely used in petroleum, chemical, nuclear power plants, food manufacturing, construction, shipbuilding, paper making, medicine and other industries.

Uses: water, beverages, beer, food, petrochemicals, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproofing, pipes, etc..

Three very high strength alloy, copper pipe, galvanized pipe is 2 times 3 times, the PP-R tube 8-10 times, can well withstand vibration and impact, has not Water Leakage, does not burst, fire, earthquake and other characteristics, so it is very safe and reliable;

Manufacturing method of alloy three pass

Hot forming

The hot pushing elbow forming process is the use of special elbow producing machine, mould and heating device, the set of billet in the mold on the forward movement in the push machine under the process in motion is heated, expanding and forming. The deformation characteristics of the hot pushing elbow is based on the law of constant volume plastic metal materials before and after deformation to determine the tube diameter, tube diameter less than three alloy, through the deformation process of mould blank control, the metal flow in the arc compressed, compensation due to expanding and reducing other parts of thin. In order to get the uniform wall thickness of three alloy.

Three alloy forming technology has the advantages of beautiful appearance, uniform wall thickness and continuous operation, is suitable for mass production, and thus become the main forming method of carbon steel, alloy three, alloy forming and application in some specifications of the three links in the.

The heating process of the forming process has intermediate frequency or high frequency induction heating (heating coil can be multi coil or single coil), flame heating and reverberatory furnace heating, which heating mode is used to decide the forming product requirements and energy conditions.

The products are still in use when they have special requirements. The stamping process of alloy three pass is made of tube blank which is equal to the outer diameter of alloy three pass, and is pressed directly in the mould by press.
