How is the weld of spiral steel tube treated?

Spiral steel pipe is mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction.

For liquid transportation: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: as a pile pipe, as a bridge; Pipe for wharf, road, building structure, etc.

Spiral steel pipe is a kind of spiral seam steel pipe welded by automatic double-wire double-side submerged arc welding process. The spiral steel pipe will feed the strip steel into the welded pipe unit, and after rolling by multiple rollers, the strip steel will gradually roll up to form a circular tube blank with opening gap. The compression amount of the extrusion roll will be adjusted to control the weld gap between 1 and 3mm, and make both ends of the welding joint flush.

Recommendation: Measuring range adjustable biaxial caliper:

The equipment can be continuously rolled seamless steel, Pilger rolling seamless just, straight seam welded pipe, spiral welded pipe and so on can be directly installed in the production line online measurement, can also be installed in the flaw detection line, inspection line to measure the outer diameter of finished pipe.

The built-in measurement range of the device can be adjusted in two groups of both sides. The adjustment of the measurement range is automatically realized by the servo motor. After the adjustment, the measurement accuracy can be guaranteed without calibration. The device can be configured with external circulation cooling system, duck-bill side blowing dust prevention system, embedded intelligent module, upper computer control system and external LED display screen, etc. At the same time, the data can be transmitted to the network database, and the data can be viewed in real time through mobile phones or computers. According to the demand, the lower part of the equipment can be configured with an automatic lifting platform to automatically adjust the height of the measuring center.
