Hebei elbow manufacturer briefly introduces the service life of carbon steel elbow

Carbon steel elbow is a very common elbow at present. The production of carbon steel elbow is diverse. Here is a detailed introduction.National standard carbon steel elbow needs normalizing + tempering treatment.Machining port, wall thickness should leave burn loss positive machining allowance.The company with advanced technology to produce advanced detection means to complete the processing.Can be customized according to customer requirements of various materials of elbow series products.The company produces seamless elbow straight seam elbow, welding elbow and so on.There are stainless steel elbow, stainless steel elbow is passivation process can be divided into wet method and dry method two.It should be noted that in the whole production process, the elbow must be corrected in a certain heat, otherwise it will not reach the corresponding effect.Long service life, the use of pipes in the rated temperature and pressure, the service life of up to 50 years, has a uv protection, when the product rub off for a long time, according to the specifications of the elbow, the process is suitable for manufacturing pitch diameter in any specifications of large elbow bend diameter ratio greater than 1.5, is the ideal way to make the large carbon steel elbow.

Seamless elbow is a pipe fitting for pipe bends.In the pipeline system used in the total pipe fittings accounted for about more than 80%, usually for different materials or wall thickness of the elbow to choose different forming process.Elbow manufacturers in the production of elbow forming process are hot push, stamping, extrusion and so on.Hot push forming: hot push elbow forming process is the use of commonly used elbow pushing machine, core die and heating device, so that the billet on the mold under the push of the machine to move forward, in the movement is heated, expanded and bending forming process.Hot push bend deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production, so it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of some specifications of stainless steel elbow.

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 reflection furnace heating. The heating method adopted depends on the requirements of the forming products and the energy situation.Stamping forming: Stamping forming elbow is early used in the mass production of seamless elbow forming process, in the common specifications of elbow production has been hot push method or other forming process to replace, but in some specifications of elbow because of the production of less, too thick or too thin wall thickness.The product is still in use when there are special requirements.The stamping of the elbow is made of tube billet equal to the outside diameter of the elbow, which is directly pressed into shape in the die by a press.Our company mainly produces seamless elbow, seamless carbon steel elbow, tee, size, cap, elbow and so on all types of pipe fittings.
