What measures are in place to ensure the processing accuracy of the "welding pipe unit"?

Welding pipe machine groups, as important processing equipment, have important measures to ensure processing accuracy. The following is an introduction to the measures to ensure the processing accuracy of welding pipe machine groups. First of all, during the processing process, the welding pipe machine group needs to ensure the stability of the equipment. Only with good equipment stability can the accuracy of the processing process be ensured. Therefore, when using the welding pipe machine group, it is necessary to install and debug it correctly according to the equipment requirements to ensure the stability of the equipment. In addition, regular maintenance and maintenance are required during use, and severely worn parts should be replaced in time to ensure the normal operation of the equipment and processing accuracy.

What industries use welding machines?

Oil casing production methods include hot-rolled seamless steel pipes and welded pipes produced by welding machines. Since welded oil casings have a weld seam, addressing issues such as matching the strength and toughness of the base material and weld seam, weld seam gray spots, and groove-like corrosion in the weld seam is crucial in production.

How is the cooling water for welding equipment recycled?

Stainless steel welding pipe machine equipment or high-frequency welding pipe machine equipment, during operation, needs to use water to cool the pipe materials. This is to allow the welded pipe materials to cool down quickly and reduce the frictional heat between the pipe materials and the mold. Another reason is to clean the surface of the pipe materials. This is a continuous process, but if unidirectional water is used, the water consumption will be very large, which not only increases the operating costs of the enterprise but also increases environmental pollution. Therefore, the cooling water must be recycled.

The equipment structure and use of a square tube forming machine

The square tube forming machine is a specialized equipment that cold-forms round steel tubes into square, rectangular, or various other shaped steel tubes. The square and rectangular steel tubes produced by this process have achieved industry-leading specifications in terms of side length and wall thickness. This machine group can also be used as a cold sizing equipment for large and medium-sized seamless steel tubes.

Market situation analysis of the current straight seam welded pipe unit

To analyze the market situation of straight seam welded pipe production lines, we must first analyze the Chinese steel pipe industry. China's domestic steel pipe industry has experienced nearly ten years of rapid development and growth. Since 2010, China's domestic steel pipe industry has occupied more than 50% of the world market, with welded steel pipes accounting for more than 45%. From this perspective, China is already a major steel pipe producer. Based on this, the future market and industrial development of welded pipe production lines are easy to predict.

The impact of frequency on high-frequency straight seam welding pipe equipment

The frequency during high-frequency welding has a significant impact on the welding process, as the high frequency affects the distribution of current within the steel plate. The choice of high or low frequency mainly affects the size of the heat-affected zone of the weld. For welding efficiency, a higher frequency should be used as much as possible. A 100KHz high-frequency current can penetrate 0.1mm of ferritic steel, while 400KHz can only penetrate 0.04mm. That is, the current density distribution on the surface of the steel plate is approximately 2.5 times higher for the latter than the former. In production practice, a frequency of 350KHz~450KHz is generally selected when welding ordinary carbon steel; when welding alloy steel and steel plates thicker than 10mm, a lower frequency of 50KHz~150KHz can be used, because the skin effect of elements such as chromium, zinc, copper, and aluminum contained in alloy steel differs from that of steel. Most foreign high-frequency equipment manufacturers now use solid-state high-frequency technology. After setting a frequency range, the frequency is automatically tracked and adjusted during welding according to the material thickness, machine speed, etc.
