The raw material of carbon steel pipe is round tube blank, which needs to be cut and processed by a cutting machine to form a billet with a length of about 1 meter, and then sent to the furnace for heating through a conveyor belt. The billet is fed into the furnace for heating, with a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in the furnace is a crucial issue. After the round tube billet is discharged from the furnace, it needs to be pierced through by a pressure piercing machine. The commonly used piercing machine is a conical roller piercing machine, which has high production efficiency, good product quality, large perforation and expansion capacity, and can pierce various steel grades. After perforation, the round tube blank is sequentially rolled, continuously rolled, or extruded by three rollers. After squeezing, the pipe needs to be detached and sized. The sizing machine uses a conical drill bit to rotate at high spe

I-shaped beams are hollow web members. For high-strength materials, hollow web members are better than solid web members in terms of weight, material, and labor saving. This cross-sectional design mainly uses the flange farthest from the centroid to resist bending moments (because the farther the flange is, the greater the moment of inertia), and mainly uses the web to resist shear. As for the inconvenience in making it, it can be solved by factory or molding. Saving materials, labor, and time is efficiency.
Place a crossbeam horizontally on two supports, and when the crossbeam is subjected to downward pressure perpendicular to the axis, it bends. Compression deformation occurs at the upper part of the crossbeam, i.e. compressive stress occurs, and the closer it is to the upper edge, the more severe the compression is; Tensile deformation occurs at the lower part of the crossbeam, i.e. tensile stress occurs, and the closer it is to the lower edge, the more severe the tension becomes. A

Lightweight, with good thermal conductivity and high low-temperature strength. Commonly used in the manufacturing of heat exchange equipment (such as condensers). It is also used for assembling low-temperature pipelines in oxygen production equipment. Copper pipes with small diameters are commonly used for conveying pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and as pressure measuring pipes for instruments.
Copper pipes have strong and corrosion-resistant properties, making them the preferred choice for modern contractors to install water pipes, heating, and cooling pipes in all residential commercial buildings.
Copper tube combines many advantages in one body: it is strong and has the high strength of ordinary metals; At the same time, it is more prone to bending, twisting, cracking, and breaking than ordinary metals, and has a certain degree of frost heave and impact resistance. Therefore, once installed, copper water pipes in water supply systems in
