Through direct investment in production sources and exclusive sales channels, MTSCO achieves end-to-end quality control from raw materials to finished products. This ensures customers receive cost-effective, fast-delivery one-stop procurement solutions.

Piercing: From Solid to Hollow

Piercing is the first critical step in seamless pipe manufacturing, transforming solid round billets into hollow pipes. Billets are heated to approximately 1200°C to enhance plasticity. Subsequently, within the piercing machine, the billet undergoes deformation under the pressure of two intersecting rollers and a piercing tool, ultimately forming a central through-hole. This process imposes stringent demands on equipment and precision. The machinery must deliver sufficient rolling force while maintaining exceptional coaxiality between the rollers and piercing tool. This prevents issues such as uneven wall thickness or eccentricity. Precise control of temperature, piercing speed, and rolling angle is critical. Improper handling may cause internal scaling, cracking, or excessive ovality. MTSCO's partner plants implement stringent controls during the C22 alloy pipe piercing stage. We ensure flawless internal quality of the blank pipe, laying a solid foundation for subsequent cold working and eliminating defects like wall thickness eccentricity at the source.

Can C22 Handle Your Extreme Conditions?

C-22 nickel alloy pipe represents the ultimate solution for demanding industrial environments. It finds extensive use in flue gas desulfurization systems, chemical processing reactors, pharmaceutical equipment, and wastewater treatment units. Whether exposed to highly corrosive media containing chlorides, iron salts, or acetic acid, or operating under complex high-temperature and high-pressure conditions, it delivers long-lasting, stable service life, ensuring production safety and continuity. Our C22 piping has been successfully deployed in numerous international chemical and environmental projects. Leveraging deep expertise in material properties, MTSCO precisely selects materials for your specific operating conditions.

FAQ Of Nickel Alloy C22 Pipes

Q1: What are the primary advantages of Hastelloy C22 over C276 alloy?

A1: Alloy C22 features optimized molybdenum, chromium, and tungsten content, delivering broader corrosion resistance. It excels particularly in highly oxidizing media and against localized corrosion (e.g., pitting, crevice corrosion), offering superior adaptability and safety in complex operating conditions.

Q2: Can MTSCO supply C22 pipes conforming to specific dimensional standards?

A2: Yes. We supply not only ASTM standard products but also customize dimensions to meet other international standards like DIN, EN, and JIS per your requirements. Our deep collaboration with manufacturing factories ensures production flexibility.

Q3: What temperature environments are C22 pipes suitable for?

A3: Hastelloy C-22 alloy maintains excellent stability at elevated temperatures, capable of sustained operation in oxidizing and reducing atmospheres up to 1040°C. However, its optimal corrosion resistance performance range depends on the specific medium. MTSCO's technical team will provide tailored material selection recommendations to ensure safe and stable pipeline operation within the optimal temperature range.
