Stainless steel thick wall pipe refers to a type of pipe made from stainless steel that has a relatively large wall thickness. The thickness of the pipe walls can vary depending on the specific application and requirements.
Thick wall pipes are commonly used in industries such as oil and gas, petrochemical, chemical, and power generation, where they are required to withstand high pressure and temperature conditions. The thicker walls provide added strength and durability, making them suitable for handling corrosive fluids and gases.
Stainless steel is chosen for these applications due to its excellent corrosion resistance and high strength-to-weight ratio. It is also known for its heat resistance, making it suitable for use in high-temperature environments.
The manufacturing process of stainless steel thick wall pipes involves hot or cold rolling of stainless steel sheets or plates into tubes, followed by welding or seamless production methods to form the final pipe. The pipes are then subjected to various finishing processes such as annealing, pickling, and polishing to ensure the desired surface finish and dimensional accuracy.
Stainless steel thick wall pipes come in various grades, such as 304, 316, 321, and 347, each offering different levels of corrosion resistance and mechanical properties. They are available in different sizes and lengths to suit specific project requirements.
Stainless steel thick wall pipes are widely used in industries that require reliable and durable piping systems capable of withstanding high-pressure and corrosive environments.
ASTM A312 316Ti Thick Wall Pipe
ASTM A312 is a specification published by ASTM International that covers seamless, welded, and heavily cold-formed ferritic, austenitic, and ferritic-austenitic (duplex) stainless steel pipe intended for high-temperature and high-pressure service. The "316Ti" designation refers to a specific type of stainless steel.
316Ti is a modified version of the standard AISI 316 stainless steel. It includes titanium additions to stabilize the material against sensitization during welding or heat treatment processes. This stabilization helps prevent intergranular corrosion, which can be an issue in stainless steels when they are exposed to certain corrosive environments, especially at elevated temperatures.
