Introduction to Quality Control Inspection Methods：

Raw Material Quality Assurance

Stringent warranty and PMI checks are conducted on our raw materials, procured from esteemed steel mills like Baosteel and Tsingshan, ensuring their superior quality. Compliance with material specifications is guaranteed through rigorous PMI checks and other meticulous inspections.

Supervised Production Process

Every phase of our seamless tube manufacturing process, including cold rolling, cold drawing, annealing, pickling, and surface treatment, undergoes meticulous oversight. Skilled engineers, equipped with advanced tools, supervise each step, capturing detailed records through photography. Process cards ensure precision and traceability throughout production.

Quality Assurance Prior to Shipment

Our dedicated QC team conducts comprehensive inspections covering appearance, PMI, size, quantity, and more. Mechanical, hardness, ultrasonic, eddy current, and hydraulic tests are performed. Additionally, we invite third-party evaluations (SGS, TUV, BV) and guarantee secure packaging and container reinforcement to maintain product integrity during transportation.

 Material Characteristics and Applications：

S32205 duplex stainless steel pipe combines excellent corrosion resistance and high strength, and can effectively resist pitting, crevice corrosion and stress corrosion cracking caused by chloride ions. Its yield strength is about twice that of traditional austenitic stainless steel (such as 304/316), and it also has good toughness and welding performance, and maintains stable mechanical properties and corrosion resistance in a wide temperature range, making it particularly suitable for use in high-strength and harsh corrosive environments.

S32205 pipes are widely used in oil and gas exploration and transportation, chemical equipment, marine engineering facilities, seawater desalination systems, pulp and paper industry, sewage treatment and other fields. Especially in chlorine-containing environments, high pressure, high temperature and other working conditions, S32205 has become an important material choice to ensure the long-term safe operation of equipment due to its excellent comprehensive performance.
