Use an air plasma cutting machine to cut the steel pipe into individual pieces. After being cut into individual steel pipes, the first three steel pipes of each batch must undergo a strict first inspection system to check the mechanical properties, chemical composition, fusion status of the welds of the Langfang acoustic pipes, the surface quality of the steel pipes, and non-destructive testing to ensure that the Langfang acoustic pipes are Only after the tube testing process is qualified can it be officially put into production.
The company specializes in the production and supply of Langfang acoustic test tubes.

Products are widely used in petroleum, natural gas, coal gas, heating, water supply, as well as power chemical industry, water conservancy, machinery manufacturing, etc.
The large-diameter Langfang acoustic pipe is made of strip steel coil plate, which is extruded at high temperature and welded by automatic double-wire double-sided submerged arc welding process. The raw materials are steel strip coil, welding wire and flux. They must undergo strict physical and chemical inspections before being put into use. The head and tail of the steel strip are butt-joined using single-wire or double-wire submerged arc welding. After being rolled into a steel pipe, automatic submerged arc welding is used for repair welding. Before forming, the strip steel is leveled, trimmed, planed, surface cleaned, transported and pre-bent. Electric contact pressure gauges are used to control the pressure of the cylinders on both sides of the conveyor, ensuring smooth conveying of the strip. Using external control or internal control roller forming.
The weld gap control device is used to ensure that the weld gap meets the welding requirements. The pipe diameter, offset amount and weld gap are all strictly controlled. Both the internal welding of Langfang acoustic pipe and the external welding of Langfang acoustic pipe use American Lincoln welding machines for single-wire or double-wire submerged arc welding to obtain stable welding specifications. The welded Langfang acoustic test pipes have all been inspected by an online continuous ultrasonic automatic flaw detector, ensuring 100% non-destructive testing coverage of the spiral welds. If the Handan large-diameter Langfang acoustic test pipes are defective in stock, an automatic alarm will be issued and spray marks will be produced. Workers can adjust process parameters at any time based on this to eliminate defects in Langfang acoustic tubes in a timely manner.
