Alloy 400 / UNS N04400 Nickel Alloy Pipe For Crude Oil Stills , Seamless Cold Rolled Tube

Alloy 400 / UNS N04400 nickel alloy pipe:

Alloy 400 / UNS N04400 nickel alloy pipe is a pipe material with excellent corrosion resistance and high temperature resistance, widely used in chemical, petrochemical, marine engineering, energy and nuclear energy industries. The alloy is mainly composed of nickel and can resist corrosion from corrosive media such as chlorides, acidic solutions and seawater, and is particularly suitable for use in high temperature and high pressure environments. Its good mechanical strength and toughness make it an ideal choice for equipment such as heat exchangers, reactors, heaters, etc. In addition, Alloy 400 also has excellent weldability, which can meet the manufacturing needs of complex piping systems and ensure stable performance in long-term use.

Introduction to Quality Control Inspection Methods:

Quality Assurance for Raw Materials

Our raw materials, sourced from esteemed steel mills such as Baosteel and Tsingshan, undergo stringent warranty and PMI checks to ensure top-notch quality. Stringent PMI checks and other inspections guarantee compliance with material specifications.

Supervised Production Process

From cold rolling, cold drawing, annealing, to pickling and surface treatment, 321 stainless tube manufacturing process is meticulously overseen. Skilled engineers, equipped with advanced tools, supervise each phase and capture detailed records through photography. Process cards guarantee precision and traceability throughout production.

Quality Assurance Before Shipment

Our dedicated QC team conducts comprehensive inspections, encompassing appearance, PMI, size, quantity, and more. Mechanical, hardness, ultrasonic, eddy current, and hydraulic tests are carried out. We also welcome third-party evaluations (SGS, TUV, BV) and ensure secure packaging and container reinforcement to ensure product integrity during transportation.
