Φ258POF tube rolling line
This line is mainly composed of the equipment such as a circular heating furnace, a conical piercing machine, a 6-stand limited-core POF continuous rolling machine, a 3-silver 14-stand sizing machine, a 6-roller vertical oblique rolling and straightening machine, etc. The reverse replacement stand of the 258 POF continuous rolling machine and 4-stand core rod support device can significantly reduce the consumption of the online threading tool and offer uniform temperature, making the product highly competitive.
Φ720 rotary pipe expansion unit
This unit is mainly composed of a stepper heating furnace, a 720 rotary pipe expander, a push forming and leveling machine (piercing machine), a five-stand sizing machine, an undercar normalizing & annealing furnace, a hydraulic pressure straightening machine, etc. It is mainly used to produce large-diameter thick-wall pipes.
Φ460POF tube rolling line
This line is mainly composed of a circular heating furnace, a conical-roller piercing machine, a 5-stand limited core rod POF continuous rolling machines, a 3-Jiang-type 14-stand sizing machine, a 6-silver vertical oblique roller straightening machine, etc. It is a three-roller continuous rolling production line for large-diameter pipes, and also a large continuous rolling unit for large-diameter pipes in the world. Compared with other units of the same caliber, this unit has obvious advantages in producing large-diameter high alloy products which are hard to be rolled. Its features of high finished product yield, low labor consumption and low rolling costs have established its ideal position.
Heat treatment line
It is used for processing of the stainless pot tube, high alloy tube, boiler tube, etc. The advanced equipment ensures that the pot tube can always achieve the ideal quality.
150t electric furnace system
It is composed of a 150t ultra-high power electric furnace, an LF outer refining furnace, a VD vacuum degassing furnace, a pot-bottom ammonia blowing unit, a wire feeder, a six-flow circular continuous casting equipment, etc. All the equipment was introduced from Mannesmann Demark GmbH in Germany. It can produce five kinds of continuous casting pipe blanks with diameters of medium 400 mm, medium 350 mm, 310 mm, medium 270 mm and medium 210 mm.
90t electric furnace system
It is composed of a 90t ultra-high power electric arc furnace, an LF outer refining furnace, a VD vacuum degassing furnace, a pot-bottom ammonia blowing unit, a wire feeder, a six-flow continuous casting machine for rectangular and round billets, etc. The main equipment was introduced from Italy, and the other equipment was made in China. It can produce five kinds of rectangular / round pipe blanks with diameters of 270 mm, medium 251 mm, 210 mm, 150 mm and 150 mmX150 mm.
Fluid pipe
The fluid pipe is a kind of pipe used to transport fluid, such as water, oil, gas, etc. There are various types of fluid pipes, including the steel wire pipe, steel pipe and plastic pipe. For selection of the fluid pipe, it is necessary to consider the factors such as material, size, wall thickness, etc. For the fluid pipe, the drawing speed affects the test results, so generally, the stress rate control or load control is used in the elasticity zone. The fluid pipe has been extensively used in various industries, such as architecture, machinery, chemical industry, etc.
Line pipe
The line pipe is a kind of pipe used to transport gas, liquid and solid, which has been extensively used in the fields such as petroleum, natural gas, chemical industry, electric power, etc.
HP boiler tube
The HP boiler tube is mainly used to manufacture steam boilers with high pressure and above made of high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel tubes. These boiler tubes are often operated under high temperature and high pressure industrial dusty environments, and the tubes are subject to oxidization and corrosion under the actions of high temperature flue gas and water vapor. Therefore, the steel tubes are required to have high durability, strong oxidation resistance and good tissue stability.
LP & MP boiler tube
The LP & MP boiler tube generally refers to the seamless steel tube used for LP boilers (less than or equal to 2.5 MPa) and MP boilers (less than or equal to 3.9 MPa). It can be used to fabricate the superheated steam tube, boiling water tube, water wall tube, flue gas tube and arch brick tube of the LP & MP boilers. It is generally made of hot-rolled or cold-rolled high-quality carbon structural steel, 10#, 20#, etc. The boiler tube is generally subject to hydrostatic pressure, crimping, flaring, flattening and other tests in order to ensure the product quality and performance.
