Square steel pipes , known for their strength and durability, have become an integral component in multiple sectors. In this article, we will explore the extensive applications of square steel pipes, highlighting their significance in industries such as construction, mechanical manufacturing, automotive, and more. Applications in Mechanical Manufacturing In the realm of mechanical manufacturing, square steel pipes are widely utilized due to their ability to withstand high levels of stress and strain. They are often used in the production of machinery and equipment, providing the necessary strength for components that require robust structural support. Additionally, they play a crucial role in the fabrication of various mechanical systems, ensuring efficiency and durability. Square Steel Pipes in the Construction Industry The construction industry greatly benefits from the use of square steel pipes. These pipes are commonly employed in engineering buildings, as they offer exceptional lo...

Hot dip galvanized steel pipe is also known as galvanized steel pipe. The name implies that it should be gone through special treatment, such as galvanized process. The meaning of galvanizing is to galvanize the outer surface or inner wall of the steel pipe in order to achieve the anti-corruption effect and improve its service life.  At present, most of the cold galvanized steel pipes are used in industry, and only the  hot dip galvanized steel pipes  are still used in cities. So the service life of galvanized steel pipe is what we are most concerned about. The following is to introduce how long the steel pipe can be used after the galvanized process. Galvanized process can increase the corrosion resistance and prolong the service life of the steel pipe. In urban areas, the service life of galvanized steel pipes can reach 30 years, and in other corrosion-prone areas,  the life is even longer. How long they can be used mainly depends on the  thickness of galvaniz...

  Seamless steel pipe  has always been a commonplace problem in the machinery manufacturing and construction industry.  The application field and market scope of seamless steel pipe are expanding, and the demand for seamless steel pipe keeps increasing. Therefore, many manufacturers of seamless steel pipes are gradually developing. The rapid development brings the small and medium-sized enterprise a powerful turning point, but it is precise that the emergence of the non-standard manufacturer makes the quality of seamless pipe in the market vary greatly and can not be guaranteed, thus causing a lot of suppliers to fail to choose a good manufacturer. When choosing seamless steel pipe manufacturers, many buyers hope to find a cost-effective one but do not consider the comprehensive factors. First, we should not take price as the only standard to measure the manufacturing strength of manufacturers. We need to carry out a comprehensive factory inspection including the factory'...

  The production process of general   seamless steel pipes   can be divided into two types: cold-drawn and hot-rolled. The production process of cold-rolled seamless steel pipes is generally more complicated than hot-rolled.   1.       The main production processes of hot-rolled seamless steel pipes: Tube billet preparation and inspection → tube billet heating → perforation → pipe rolling → steel pipe reheating → fixed (reduced) diameter → heat treatment → finished pipe straightening → finishing → inspection  △  (non-destructive, physical and chemical, bench inspection) → storage   2.       Main production process of cold rolled (drawn) seamless steel pipe: Blank preparation → pickling and lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection   Changsha Xiangjia Metal Materical Co., Ltd.  the Steel Pipe Division of ADTO GROUP, is one of the leading manu...

  OCTG pipes  are mainly used for drilling oil and gas wells and transporting oil and gas. It includes oil drill pipe, oil casing pipe, and oil pumping pipe. Oil drill pipe is used to connect drill collars and drill bits and transmit drilling power. Petroleum casing is mainly used to support the well wall during drilling and after completion to ensure the progress of the drilling process and the normal operation of the entire well after completion. The pumping pipe used to transports the oil and gas at the bottom of the oil well to the ground. The oil casing is the lifeline to maintain the operation of the oil well. Due to different geological conditions, the stress state is complex, and the combined action of tensile, compressive, bending and torsion stresses on the pipe body, which puts forward higher requirements on the quality of the casing. Once the casing is damaged for some reason, the entire well may be reduced production or even scrapped. According to the strength of ...

 Defects that are easy to produce in the welding pipe are pores, hot cracks and undercuts. 1. Bubbles. Bubbles mostly occur in the center of the weld bead. Because hydrogen is hidden in the weld metal in the form of bubbles. Therefore, the measure to eliminate this defect is to remove the rust, oil, moisture and moisture of the welding wire and the weld. Secondly, the flux must be dried well to remove moisture. In addition, it is also very effective to increase the current, reduce the welding speed, and slow down the solidification speed of the molten metal. 2. Sulfur crack (crack caused by sulfur). When welding plates with a strong sulfur segregation zone (especially soft boiling steel), the sulfide in the sulfur segregation zone enters the weld metal to produce cracks. The reason is that the sulfur segregation zone contains low-melting iron sulfide and the presence of hydrogen in steel. Therefore, in order to prevent this, it is effective to use semi-killed steel or killed steel ...
