How to avoid damage to welding pipe equipment

Generally speaking, the formulation of straight seam welded pipe unit production line equipment must comply with the operating procedures. Operators must not contact the die during the operation of the welded pipe unit, and must pay attention to placing their hands in the direction of the pipe outlet to avoid the impact on their health and safety due to improper operation. In addition, before operation, the operator of the welded pipe unit should check whether each lubrication point of the unit is lubricated, otherwise, add some lubricating oil to ensure the normal operation of the unit. During the use of the welded pipe equipment, it is necessary to use some high-temperature resistant synthetic composite aluminum-based lubricating grease to avoid damage to the welded pipe equipment.

Precautions for Yangzhou welded pipe unit when producing oil casing pipes

With the continuous development of China's construction industry, the technical level has also been greatly improved. In recent years, even some second- and third-tier cities have been able to build more complex structures. Due to China's continuously increasing population, in order to meet more housing needs on limited land, improvements must be made in construction to provide the necessary housing for people, so that society can develop better. Steel pipes are indispensable in the construction industry and provide material support for more challenging construction projects.

What are the future prospects of the square tube machine industry?

Due to various historical factors and national conditions, the stainless steel welded pipe industry in China is mainly driven by local private investment. Therefore, it entered the market economy earlier than most other steel industries. Except for the relatively high concentration of oil pipe manufacturers, the welded pipe industry in China is characterized by a more decentralized structure.

What are the trends in the production and demand for square tube machines?

Current Status of China's Steel Pipe Machinery Industry: After nearly 10 years of rapid development, China's steel pipe industry has become the world's largest steel pipe producer. In 2010, China's steel pipe output accounted for more than 50% of the world's total, with seamless steel pipes accounting for over 60% and welded steel pipes accounting for over 45%. China has reached advanced global standards in terms of output, variety, quality, equipment, and production technology.

Pipe manufacturer introduces the detailed differences between two different types of equipment

Square tube is a hollow square section steel, also known as cold-formed steel section. It is made of hot-rolled or cold-rolled strip or coil as raw material, cold-bent into shape, and then high-frequency welded into a square section shape and size steel. Except for the increased wall thickness of hot-rolled extra-thick wall square tubes, the corner dimensions and edge straightness reach or even exceed the level of resistance welded cold-formed square tubes.

How to handle cracking issues encountered during the operation of welding pipe equipment

When using pipe welding equipment, especially in welding techniques, we often encounter the problem of seam cracking. Seam cracking refers to the inability of the weld seam to fully adhere during welding, resulting in substandard product quality. Cracks in pipe welding equipment are typically several centimeters or even larger. So, what causes seam cracking during pipe welding?

Power control methods and characteristics of a welding machine

As a crucial processing technology in mechanical manufacturing, according to statistics from developed industrial countries, steel used annually for manufacturing welded structures accounts for approximately 70% of total steel production. Submerged arc automatic welding is a welding method generally used for welding large-diameter pipelines, containers, oil tanks, inner and outer longitudinal (circumferential) seams of boilers, and various deep-groove butt welds. It is a highly efficient welding method widely used in the mechanical manufacturing industry. Through careful study of each component of the submerged arc automatic welding system, and based on customer's technical requirements, a programmable logic controller (PLC)-based automatic control system for pipe welding machines was designed using the Siemens S7-200 PLC system. The electrical automatic control part of a cantilever single-head submerged arc automatic welding machine was successfully retrofitted. Finally, through debugging, the retrofitted system met the user's technical requirements.
