Thermal Expansion Pipe Production Technology and Market Application

Thermal expansion pipe is a form of pipe expanding the use of afterburner hydraulic steel pipe from the pipe wall, so that caliber bulged outward, thus forming processes.

Thermal expansion process is a way of processing steel processing, the principle is very simple process is to a large diameter steel pipes of small diameter pipe. Processing of large-diameter steel pipe specifications randomness is relatively large, according to the customer's needs and production.
Large diameter steel pipe thermal expansion process: This process uses a two-step push Flaring Machine expanding technology, induction heating, hydraulic technology, and its reasonable method, the lower power consumption, to produce good quality products . Due to the wide range of raw materials and product specifications applicability, flexible and volatile, so instead of the traditional steel industry pull Dial expanding technology. Can be solved in a short supply of a large number of large-diameter steel pipe, thermal expansion technology will be so great to use. Thermal expansion of large diameter pipe cooling method is achieved by controlling the cooling system, including: fan, water pump. If steel by heating at a temperature between 950  ~ 980 , when the thermal expansion is not fully rolled out the tail pipe sizing mill, pipe does not rotate after rolling, when the thermal expansion of large diameter pipe tail completely out of the rack, can change the angle of the roller press to set the tilt angle in the horizontal plane, the thermal expansion of seamless steel pipe with its axis along the rolling direction of the spiral forward, eventually reaching the cooling rate process requirements; subsequently implemented into the chain-air cooling to room temperature cooling bed . Application of thermal expansion of steel pipe: steel pipe in recent years due to the increasing demand for large-diameter, large diameter pipe production has continued to increase, we can say the heat expanding technology is well developed, this technology is relatively advanced for the original production process, lower production costs, and production quantities of a single species is not much requirements, so the thermal expansion pipe again later development of the market will get more use.
Thermal expansion pipe density is relatively low, but a strong contraction of the steel pipe, using a two-step expansion of the machine set-propelled expanding cone mold technology, digital intermediate frequency induction heating technology, hydraulic technology in one machine, with its reasonable process, lower energy consumption, lower capital investment, good product quality, a wide range of raw materials and product specifications applicability, variable and flexible adaptability to low-input production batchBusiness Management Articles, replace the traditional steel industry pull dial expanding technology.
