Testing equipment and technology

Magnetic leakage detection system for steel pipes

Dayang Steel Pipe is equipped with steel pipe leakage magnetic flaw detection system. This system adopts the scanning method of pipe spiral advancement, segmented longitudinal and transverse magnetization, signal acquisition and channel processing of steel pipe, which can subdivide the defective signals and objectively respond to the defective conditions. The longitudinal and transverse probe adopts a strip-shaped probe shoe, which has a compact structure to ensure the reliability of the product and provide effective quality control for the petroleum equipment series products.

Ultrasonic flaw detection system for steel pipes

Dayang Steel Pipe is equipped with an ultrasonic flaw detection system for steel pipes, which is suitable for accurate flaw detection after the production of workpieces or random inspection of finished products. The automated flaw detection process includes automatic loading, roller conveyor transfer, ultrasonic flaw detector inspection and discharging system, and the inspection result triggers automatic alarm, marking and sorting.

Tube Hydraulic Press Flaw Detection System

The company is equipped with steel pipe hydraulic press flaw detection system, which utilizes oil-water balance control to conduct hydrostatic pressure resistance test on steel pipe, applicable to petroleum pipe and pipeline pipe with pressure-bearing requirements. The outer diameter range is 60~457mm.

Physical and Chemical Testing Center

Our physical and chemical inspection center laboratory is a key laboratory in Shandong Province, with a building area of 2,000 square meters, more than 20 professional and technical personnel, equipped with a series of advanced testing equipment, including metallographic specimen cutter, universal testing machine, spectrometer, etc., which provides strong support for the performance analysis and technical appraisal of the steel pipe.
