When a batch of steel pipe production is completed, it needs to be tested by professional and authoritative institutions to ensure the quality.Generally, our commonly used testing agencies are SGS, BV, TUV

Chemical Analysis
Main purpose of chemical analysis to determine whether the batch product accord with standard of the grade of steel products, and to the analysis of the results should be taken as the basis of the judgement of the batch product.

Metallurgical Micriscope
Test metal organization, such as rolling, forging and heat treatment processing leads to changes in microstructure, grain size inspection or the distribution of nonmetallic inclusion and other groups

Ultrasonic Flaw Detector
Ultrasonic flaw detection has high detection sensitivity, to crack in the steel pipe straight defects such as sensitive, also can detect non-metallic.

Impact Test Machine
Low temperature and impact test of low temperature tank, with impact testing machine is a kind of form a complete set of low temperature environment for the sample to a special test equipment, widely used in all kind of related field.

Hardness Test
The main purpose of the hardness test is to determine the applicability of the steel pipe, or steel pipefor a specific purpose by hardening or softening effect, Methods is including brinell, rockwell and vickers hardness.

Hydraulic Tester
Checking the quality of pipe connection leak test,check the vacuum pipe system maintain the performance of the vacuum test and based on the fire safety considerations for the leakage test, etc.

Bending Machine
This machine test special plug lead and folding strength of wire. The sample test is fixed on the fixture, and add a certain load, test fixture swinging, examine the break rate after a certain number of times, or until all bolt can’t
electricity to check its total number of swing. The function of automatic counting, bending specimen is no electricity to break, and can automatically stop the operation.
