Introduction of Welded Austenitic Stainless Steel Sanitary Tubing / Tubes for Boiler / Heat–Exchanger / General Service Tubing

 

ASTM A249, ASTM A269, ASTM A270, AS 1528.1, JIS G3447, JIS G3463, CNS 6668, CNS 7383 , EN 10357 round tubes categorize the technical delivery conditions into two test categories for stainless steel welded round tubes which are intended for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.

Years of experience and innovation had been put into developing sanitary tubing technology. The same technology is then applied in the manufacturing of tubes for boilers, heat exchangers and general service tubing purposes.

Products made of Austenitic series stainless steel with optional grades in MT-304, MT-304L or MT-316L are both durable and verstaile.
The sanitary tubes are commonly utilized in corrosion-resisting and low/high temperature service applications, such as dairy and food industry.
Welding is performed only by qualified personnel.
