FAQs - ASTM A53 Grade B Pipe
What is Nickel 200 seamless pipe used for?
Nickel 200 seamless pipe is used wherever maximum corrosion resistance and purity are needed, including oil & gas drilling, chemical processing, food-grade equipment, and marine piping systems.
What is the difference between Nickel 200 and Nickel 201 pipe?
Nickel 200 has a higher carbon content suited to general service below 315°C, while Nickel 201 has low carbon content designed for high-temperature applications above 315°C, avoiding embrittlement issues.
What size range do you supply for Nickel 200 seamless pipes and tubes?
Kalpataru Piping supplies Nickel 200 pipes and tubes in sizes from 4 mm to 219 mm, with wall thickness from 0.5 mm to 20 mm, and lengths up to 13,500 mm, fully customisable to your project.
Do you provide mill test certificates with every order?
Yes, every consignment of Nickel 200 seamless pipe is supplied with EN 10204 3.1 or 3.2 mill test certificates, and third-party inspection can be arranged on request.
Is Nickel 200 pipe suitable for high-temperature applications?
Nickel 200 performs well up to around 315°C (600°F). For higher-temperature service, we recommend Nickel 201, which has a low-carbon composition designed to resist embrittlement at elevated temperatures.
Can Kalpataru Piping supply custom Nickel 200 pipe sizes and forms?
Yes, we manufacture custom sizes, thicknesses, and forms including round, square, rectangular, and hydraulic tube, tailored precisely to your project drawing or specification.
Do you export Nickel 200 seamless pipes and tubes internationally?
Yes, Kalpataru Piping exports Nickel 200 seamless pipes and tubes to over 40 countries worldwide, with complete documentation, secure packing, and reliable shipping support.
