Applications JIS G high-pressure carbon steel pipes are extensively used for pressure service, high pressure service and high temperature software. This high pressure steel pipe is also utilized in boiler, electric power, machinery, gas tank, chemical engineering, offshore and petroleum engineering, etc. Wall thickness on this high pressure steel pipe ranges from 2. The length is millimeters.

Competitive Advantages JST has three sets of advanced hydrostatic press to check on the compactness of steel pipes. Common actions like judge whether there exists leakage phenomenon of this carbon steel pipe through naked eyes or pressure drop.

The maximum test pressure reaches Mpa, which meets the requirements of questionable steel pipes. Similar to provide ultrasonic flaw detection test or eddy current inspection, as well as provide relevant inspection documents.

JST can also do nondestructive inspection for G carbon steel water lines. We will get rid of disqualified high-pressure steel pipes and ensure that we manage to supply boiler, superheater and heat-exchanger pipes with stable performance and quality. For the surface defects, JST professional inspection personnel will do polishing, removal, repair nicely series of processes based on their specific characteristics.

These processes are carried out in accordance with specifications. After treatment, inspectors will instigate a second inspection for carbon steel pipes. They also measure the wall thickness of high pressure steel pipes and make their performance more ferme. PackagingWe package our products in bare, bundles, crates or crate protection in the both sides of tubes. Specifications of G Carbon Steel Pipe 1.
