Production technology of thread fitting
Thread fitting consists of a sealing ring, a connecting part and a used to connect the pipe union nut, therefore, described in the sealing ring is designed to have one or more of the knife blade ring.By putting the union nut twist to the connection part, can make the hole knife inserted into the connection part of the cavity, the hole cavity with a conical surface.The outside of the sealing ring at the side of the nut has a circular reinforcement.Described in the annular reinforcement in its department toward the small ring at the transition zone formed a torus.Described formed by strengthening part of the cutting ring ring faces to the slope of the pipe axis to 45 ° to 90 °.When fully assembled, annular axial length of reinforcement as to set it on the surface of the ring heat transfer element to its negative image structure or its transfer to the connection part of the face.Heat transfer element with three dimensional shape, the outline of its negative image can be transfer to the connection parts on the surface.With the method of similar to die, pressure from the assembly will be negative as imprinted onto the surface of the connection part.

Advantages of thread fitting
Industrial use of thread fitting
are generally made of metal, high pressure, material is carbon steel,
stainless steel, alloy steel, brass, etc.;Life in the nipple material
generally have a PC, PVC, PE, PPR, etc. Use the nipple has seven
advantages, high joint strength, stable performance, fast connection,
wide application range, convenient for management, economic/social
benefit is remarkable, the intensity of labor is low.
1, high joint strength, according to the principle of cold work hardening steel on steel rolling straight thread strength greatly increased, so that the straight thread connection of tensile strength is higher than the tensile strength of steel.
2, stable performance, connection process is not affected by the quality of the workers, so the performance is stable.
3, fast connection, because use over-the-counter precast, field assembly connection manner, so steel prepared wire head can be prefabricated reinforced yards of reserves.Time limit is tight, just in the construction site The assembly workers.
4, wide application range, basically do not have any restrictions on the application be used, more suitable for the bending steel, fixed steel bar, steel reinforcement cage and other steel can't rotation of field.
5, easy to manage, won't appear the sleeve and the phenomenon of the steel bar does not match, test is more convenient.After several hours of operation is simple, ordinary workers, learning can become skilled workers.
6, economic benefit, social benefit is remarkable, shorten the construction period, improve the engineering quality, reduce energy consumption, environmental protection, reduce equipment investment, additional cost is low, has obvious economic benefits and social benefits.
7, low labor intensity, a silk head only need one step process in a dedicated thread rolling machine.

Thread fitting, including a seal ring, a connecting part and a union nut which used to connect the pipe, therefore, described in the sealing ring is designed to have one or more of the knife blade ring.

When fully assembled, annular axial length of reinforcement as to set it on the surface of the ring heat transfer element to its negative image structure or its transfer to the connection part of the face.Heat transfer element with three dimensional shape, the outline of its negative image can be transfer to the connection parts on the surface.With the method of similar to die, pressure from the assembly will be negative as imprinted onto the surface of the connection part.
