KC-SCT manufactures seamless stainless steel pipes conforming to ISO/EN standards, and delivers them to each customer through natural gas annealing and pickling processes. Some pipes can be delivered through protective atmosphere annealing (bright annealing) processes. Customers need to give us a clear explanation.
1. Material
Several materials in austenitic stainless steel.
2. Cold processing technology
The combination of cold rolling and cold drawing helps to improve the consistency of the pickling color of the inner and outer surfaces of the pipe, and ensures that the inner and outer surfaces are smooth and delicate, and a high-quality metallographic structure can be obtained after annealing.
3. Production standards
EN 10216-5 TC1
PED 97/23/EC, AD 2000

6. Surface delivery status
ISO/EN seamless stainless steel pipes are available in two delivery states:
6.1 Solid solution pickling: delivery after natural gas heat treatment, pickling passivation.
6.2 Bright Annealing: After the atmosphere protection heat treatment, it can be delivered without pickling. The specific content needs to be negotiated with the purchaser!
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 tube, which meets standard EN 10246-2.
8. Other inspections
For heat exchanger pipes, sampling inspections such as stretching, flattening, flaring, grain size, and hardness are carried out in accordance with the standards.DIN EN ISO Pipes manufacturers
