Seamless elbow manufacturing process:

Seamless elbows do not cause corrosion, pitting, corrosion or wear.Stainless steel is also one of the strongest materials in building materials.Because stainless steel has good corrosion resistance, it enables structural components to permanently maintain the integrity of the engineering design.Rolling seamless elbow pipe materials are tubular billet, round tube embryo through cutting machine cutting the growth degree of billet is about one meter, and the conveyor belt to the heating furnace. Billet heating are fed into the furnace, the temperature is about 1200 degrees Celsius. In furnace temperature control is a crucial problem. Circular tube billet after go through pressure punch wear empty. Fuel for hydrogen or acetylene.

General is one of the more common punch is tapered roller puncher, this kind of punch production efficiency is high, the products of good quality and large amount of perforated hole enlargement, can wear a variety of pipe fittings. After perforation, circular tube billet has been three-roll skew rolling, rolling or extrusion. Extrusion to take off the tube sizing. After sizing mill by taper drill bits high-speed steel into embryo punch, form fitting

 
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.

Seamless elbow manufacturers

Seamless elbow classification:

A seamless bend is a fitting for a bend in a pipe.In the total pipe fittings used in the pipeline system, the proportion is the largest, about 80%.Generally, different forming processes are selected for the elbows with different material wall thickness.At present.The forming process of seamless elbow commonly used by manufacturers includes hot pushing, stamping, extrusion, etc

Seamless elbow is also called seamless steel pipe elbow, seamless elbow pipe fitting due to its manufacturing process, and divided into hot rolling (extrusion) seamless elbow pipe fitting and cold drawing (rolling) seamless elbow pipe fitting two kinds.Cold drawn (rolled) tube is divided into round tube and shaped tube two kinds.

The raw material for rolling seamless elbow pipe fittings is round tube blank. The round tube blank is cut by cutting machine and processed into blank with a length of about one meter, and then sent to the furnace by conveyor belt for heating.The billets are fed into a furnace and heated at a temperature of about 1200 degrees Celsius.The fuel is hydrogen or acetylene.The temperature control in the furnace is the key problem.Generally more common puncher is tapered roller puncher, this kind of puncher has high production efficiency, good product quality, large perforation diameter, can wear a variety of pipe fittings.After perforating, the round tube blank is successively rolled, rolled or squeezed by three high.After extrusion, take off the pipe to determine the diameter.The sizing machine rotates the tapered bit into the steel blank to punch holes at high speed to form the pipe fitting
