Precision steel tubes have a wide range of uses in various industries, including automotive, aerospace, construction, and manufacturing. Some common applications of precision steel tubes include: Hydraulic systems: Precision steel tubes are used in hydraulic systems to transport fluids or gases under high pressure. Instrumentation and control systems: They are used in instrumentation and control systems to transmit signals and measure pressure or temperature. Automotive industry: Precision steel tubes are used in the production of engines, fuel injection systems, and exhaust systems. Aerospace industry: They are used in the production of aircraft engines, landing gear systems, and hydraulic systems. Manufacturing industry: Precision steel tubes are used in the production of machines and equipment, such as CNC machines, printing presses, and textile machines.

Mechanical steel tube is one of the most commonly used seamless steel tube. At the same time, the weight is relatively light,.it is an economical section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill rods, bicycle frames, and steel legs used in construction construction, etc.

The difference between cold drawing and cold drawing: Cold drawing and cold drawing are two different methods of metal cold processing, and the two are not the same concept. Cold drawing refers to the method of applying tension at both ends of the metal material to cause the material to produce tensile deformation; cold drawing refers to the method of applying a pulling force at one end of the material to make the material pull out through a mold hole, and the hole diameter of the mold should be larger The diameter of the material is smaller. The cold drawing process causes the material to have extrusion deformation in addition to the tensile deformation, and the cold drawing process is generally carried out on a special cold drawing machine. Materials that have been cold drawn have better properties than those that have been cold drawn. Main application: For automobiles, motorcycles, refrigeration equipment, hydraulic parts, pneumatic cylinders, and other customers who have high requirements for steel pipe precision, smoothness, cleanliness, and mechanical properties.

The inspection method can be to use soapy water to wipe the gaps of the joints of the annealing furnace to see if there is air leakage

How to distinguish precision seamless steel pipes from common seamless steel pipes

There are 20 different steel grades and types of oil casing and tubing in H40, J55, K55, M65, N80, L80, C90, T95, C95, P110, Q125

Due to the advanced production technology and high production efficiency, the production cost of ERW steel pipe is much lower than that of seamless steel pipe, and the price is also more advantageous.

Compared with SSAW, there is little difference in price between ERW steel pipe and SSAW steel pipe. The length of SSAW weld joint is about 2~3 times of ERW weld joint, and its internal weld tumor has no technical ability to remove

First of all, it is necessary to understand the type, specification, performance and scope of use of the pipe. It is better to investigate the application of the pipe in other similar pressure pipes, and then determine the material of the pipe according to the following principles.

Good heat preservation effect: 3PE anti-corrosion spiral steel pipe has good heat preservation performance, and the heat loss is only 25% of that of traditional pipes. Long-term operation can still save relatively large resources and significantly reduce energy costs.

old galvanized pipe and hot-dippedgalvanized pipe has a great difference in the operation mode. The zinc in hot-dippedgalvanizing is obtained at 450 degrees Celsius to 480 degrees Celsius, while the zinc in cold-galvanized steel pipe is obtained by electroplating at room temperature.

Stainless steel pipe can be divided into equal section pipe and variable section pipe according to the shape of the vertical section. Variable section tube has conical tube, step tube, periodic section tube and so on.
