Our quality policy is to continuously improve the quality management system, provide high-performance seamless 1/4 Stainless Steel Instrument Tube, cold drawn Electro Polished Pipes, seamless Natural Gas Annealed Stainless Steel Pipes and constantly meet customers' demands and expectations for product quality. We embody our corporate social responsibility in a series of actions to improve our own connotation and actively return to society. Communication and execution, team innovation, satisfaction and win-win are our business philosophy and purpose.

Seamless stainless steel bright annealed tube is a kind of heat treatment and surface delivery requirements in the production process of steel pipes. The heat treatment is in the state of protective gas (H2+N2 mixed gas), and the temperature control range is 1010-1100 degrees Celsius. It is seamless for clean cleaning. The stainless steel tube is annealed. This heat-treated stainless steel pipe has excellent surface quality, good mechanical properties, and strong bending plasticity, which is convenient for customers to perform various bending, welding, Lok connection and other processing.

Bright annealing heat treatment can be applied to the manufacturing process of instrument pipes, hydraulic pipes, high-pressure pipes, precision pipes, fluid conveying pipes, high-purity gas/bulk gas conveying pipes, automobile pipes and other industries. The inner surface of bright annealed steel pipes is clean and free. Oil, no impurities, no falling particles, corrosion resistance and other properties can meet the pollution-free transportation of various fluid media.

Details of the bright annealing tube manufactured by KC-SCT

Strict production control system:

-Cold rolled or cold drawn control tolerance

-Excellent oil control and grease removal technology

-Strictly monitor the natural gas heat treatment process and bright heat treatment.

-Environmental protection and efficient pickling passivation + neutralization + cleaning

-A rigorous quality inspection team (dimension inspection, surface inspection, non-destructive inspection, mechanical performance inspection, metallographic inspection)

1. Material

The materials listed above are often manufactured, and materials within national standards can also be provided for manufacturing.

2. Standard

3. Specification

#It is possible to customize pipes with outside diameter and wall thickness not specified in the standard;

4. Tolerance

The tolerances of the outer diameter and wall thickness of the pipes produced in accordance with the standards can also be agreed with the purchaser separately;

Special (non-standard) pipe tolerances for outer diameter and wall thickness can be more precise.

5. Surface delivery status

Bright annealing: atmosphere protection heat treatment, the inner and outer surfaces are bright and smooth.

Bright annealed tube customization can make requirements for the roughness or polishing of the inner and outer surfaces:

The accuracy of the inner and outer surface roughness of bright annealed steel pipes can be met by mechanical polishing or without mechanical polishing;

6. Clean cleaning process

The steel pipe manufacturing process adopts ultrasonic + degreasing cleaning process to effectively remove various pollutants generated in the pipeline manufacturing.

7. Non-destructive inspection

Each stainless steel pipeline is tested according to the standard of water pressure testing and eddy current testing:

Hydrostatic pressure detection: maximum pressure 20Mpa, time 5 seconds

Eddy current flaw detection: Perform inspection according to standard sample tubes, and comply with standards such as ASTM, JIS, ISOENDIN, GB, etc.

8. Other inspections

Perform random inspections of stretching, flattening, flaring, grain size, hardness, etc. according to the standard.
