Seamless carbon steel pipes are made of steel ingots or solid billets through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The raw material of Carbon Steel Pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released from the furnace, it is pierced through a pressure punching machine. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls.
Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow - liquids and gases (fluids), slurries, powders and masses of small solids.
Hot rolled seamless steel pipe deformation process can be summarized as three stages: extension, perforation and finishing. Hot rolled seamless steel pipes is relative to the cold-rolled, cold rolling is below the recrystallization temperature of the rolling and hot rolled is carried out at above the recrystallization temperature of the rolling. Hot rolled seamless steel pipe can damage the refinement of the crystal grains of the steel, cast microstructure of the steel ingot and eliminate the defects of the microstructure so that the the steel organization compacting, improves the mechanical properties. This improvement is reflected in the rolling direction so that the steel is no longer at a certain extent isotropic; pouring the formation of bubbles, cracks and osteoporosis, under high pressure and temperature can also be welded together.
Hot Rolled Steel Pipes (Seamless Tube) in different size, specifications, grades & thickness as per the client's requirements. The range offered by tubes is available as per the international & national standard and can be available from us at affordable prices. These pipes are used in various application industry like shipbuilding, power plants, oil and gas, automotive, sugar mills and distilleries, cement and construction industries etc.

High-end sulfuric acid centrifugal blower wins
Recently, the Hubei Provincial Intellectual Property Office recognized Hubei Shuangjian Blower Manufacturing Co., Ltd. by awarding them the "Heishan Sulfuric Acid Centrifugal Blower" title for outstanding patent projects in Hubei Province. This achievement highlights the company's innovation and commitment to technological advancement in the field of industrial equipment.
The "High-efficiency Sulphuric Acid Centrifugal Fan for Plateau" is a groundbreaking environmental and energy-saving fan developed by the company. It was first introduced in 2005 and officially granted an invention patent by the State Intellectual Property Office in November 2007. Designed with aerodynamics in mind, this fan features a unique low-speed two-stage impeller compression system, which significantly improves efficiency and reduces energy consumption.
One of the key innovations of this product is the use of acid-resistant stainless steel, which not only enhances durability but also minimizes both aerodynamic and mechanical noise. Additionally, it effectively addresses the issue of rotor imbalance, ensuring smoother and more stable operation.
This advanced technology has proven to be highly cost-effective. Each unit can save over 150,000 yuan in operational costs, while simultaneously increasing sulfuric acid production and reducing the emission of sulfur dioxide gas, thereby contributing to a cleaner and healthier environment.
The success of this project reflects Hubei Shuangjian Blower Manufacturing Co., Ltd.'s dedication to sustainable development and technological leadership in the industry. Their continued efforts in research and development are setting new standards for innovation in China’s manufacturing sector.
