ASTM B622 Nickel Alloy Tube For Chemical Environments , Alloy G-35 / UNS N06035 Seamless Tubing

ASTM B622 nickel alloy pipe:

ASTM B622 nickel alloy pipe is a pipe with excellent corrosion resistance and high temperature resistance, which is widely used in chemical, oil and gas, marine engineering, aerospace and nuclear energy industries. It is made of nickel and its alloys (such as Inconel, Incoloy, etc.), which can withstand the challenges of extreme temperatures and corrosive media, and is suitable for chemical reactors, heat exchangers, oil and gas pipelines, and seawater desalination systems. The good mechanical strength, toughness and welding properties of nickel alloy pipes make it an ideal choice for long-term stable operation in high pressure, high temperature and corrosive environments.

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.
