Advantage | Superior surface finish , better mechanical property ; more precise dimension ; perfect inspection method and inspection equipment |
Heat Exchange TubeProcess : |
We use Cold Drawn techonology to produce U bend tube |
U bend tubes produce will accordance to customer's drawings |
To avoid oxidation , inert gas (Argon) is passed through tubes ID at the required flow rate |
The radius is checked for its OD and wall thinning with the recommended specification |
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 |
Visual inspection for waviness and cracks is done with Dye Penetrant Test |
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 .
