Product Description:

carbon steel tee ,we can make the carbon steel tee according to client requirement . All pipe fittings which form cold process need to do heat treatment. After heat treatment , the quality of the carbon steel tee will be much better and the structure of the material will be much steady .

Product Show

Carbon steel tee producing process is very easy . Firstly ,we need cut the pipe into pieces and then put the pipe into the cold forming tee machine and after finishing the tee ,we will need to cut the cap , do heat treatment and beveling , shot blasting , and marking . For the carbon steel tee ,we can make the carbon steel tee according to client requirement . All pipe fittings which form cold process need to do heat treatment. After heat treatment , the quality of the carbon steel tee will be much better and the structure of the material will be much steady .

Seamless elbow forming method:

1. Forging and pressing method: stretch the end or part of the pipe with the forging machine, so as to reduce the outside diameter. Commonly used forging machines include rotary type, connecting rod type and roller type.

2. Rolling method: generally without mandrel, suitable for inner round edge of thick wall tube.The core is placed in the tube, and the roller is used for edge processing.

3. Stamping method: expand the tube end to the required size and shape with tapered core on the press.

4. Bending forming method: there are three methods commonly used, one method is called stretching method, another method is called stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, an adjustment roller, adjust the fixed roller distance, the finished pipe is bent.

5. Bulking method: one is to place rubber inside the tube and compress it with punches to make the tube protruding and forming;Another method is hydraulic bulging, in which a liquid is filled in the middle of the tube, and the liquid pressure pushes the tube into the desired shape. This method is used in most of the production of bellows.

Seamless elbow technology:

Carbon steel seamless elbow forming technology is to choose the special elbow pipe parts of the push machine, core mold and heating equipment, so that the blank on the mold in the push machine to move forward, in the movement of heating, expanding and zigzag forming process.Hot pushing elbow pipes deformation characteristics is based on volume before and after plastic deformation rule of metal materials concluded that tube billet diameter, chooses the pipe diameter is less than the diameter of the elbow pipe fittings, through core model control billet deformation process, the arc is tight spot metal activity, counter to other parts of the thinned by expanding, then get the uniform wall thickness of elbow pipe fittings.Hot push pipe fitting forming technology has the characteristics of beautiful appearance, uniform wall thickness and continuous work, suitable for mass production, so it has become the primary forming method of carbon steel, alloy steel and carbon steel elbow, and also applied in the forming of some standard stainless steel elbow pipe fitting.The heating methods of the forming process include medium frequency or high frequency induction heating (heating ring can be multi-turn or single turn), flame heating and reflective furnace heating. The choice of heating methods depends on the demand of the forming commodity and the power status of the decision.
