Seamless Mechanical Tubing
Leave a message
The Stainless Steel mechanical tubing is available in square, rectangular, round and other custom shapes. These shapes have benefits in different application types. The round mechanical tubing is the most commonly used. There are different types of production methods such as cold drawing, hot drawing, forging, EFW and ERW types. The seamless mechanical tubing is made through drawing procedures. These are dimensionally accurate tubes. There are special procedures as well. The seamless stainless steel mechanical tubing can be made up of different types of materials. There are ferritic, austenitic and duplex stainless steels used for the manufacturing of these tubes. The 304 mechanical tubing is the most widely used for its less cost and strength. However, when corrosion resistance is considered as a requirement, the 316l mechanical tubing is used. The 316L material has low carbon and has molybdenum added to the chromium nickel austenitic stainless steel. The chromium, nickel and molybdenum contents allow the 316 mechanical tubing to withstand chloride ion stress corrosion cracking. This type of tubes are used in sea water, marine, food processing and in wastewater management applications.
