Product Description

ASTM A269 19.05 * 2.11 Heat Exchanger Tube Seamless Tubing , Pickling And Soft Condition

ASTM A 213 / A 213M ASME SA213 / SA213M Specification for Seamless Ferric and Austenitic Alloy -Steel Boiler , Su[perheater , and Heat-Exchanger Tubes
ASTM A 249 / A 249M Specification for Welded Austenitic Steel Boiler , Superheater , Heat-Exchanger , and Condenser tubes

Application :

Boiler tube applies to petroleum , chemical industry , electric power , boiler , high temperature resistant , low temperature resistant , corrosion resistant . The size can be made according to the customers requirements . High pressure boiler pipe applies to container , petrochemical and so on . Note : Generally , high pressure boiler pipe’s working pressure above 9.88Mpa and working temperature between 450 to 650 .

Process :

1 . We use Cold Drawn techonology to produce U bend tube
2 . U bend tubes produce will accordance to customer's drawings
3 . To avoid oxidation , inert gas (Argon) is passed through tubes ID at the required flow rate
4 . The radius is checked for its OD and wall thinning with the recommended specification
5 . We'll choose three different position or as customer's require to make sure tubes quality . We'll do physical properties and micro-structure test
6 . Visual inspection for waviness and cracks is done with Dye Penetrant Test
7 . Each tube is then hydro tested at the recommended pressure to check for leakage

MTSCO heat exchanger tube with pickling and annealing surface is very popular in boilers and heat exchangers industry , water heater industry , air-conditioning industry etc . This kind of seamless tubes are have a very important position in our all products .
