ASTM A269 TP321 / 321H Stainless Steel Heat Exchanger U Bend Welded Tube For Boiler
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 .
| 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 |
