Welded tubes are the strips which are first formed into an open tube seamless and are then subsequently welded. These Welded U tubes are manufactured using Stainless Steel because of its good characteristics. The industry use mainly SS 347 and 347H are highly used because of its good mechanical and physical properties.
Alloy 347 is a stabilized SS grade that offers excellent resistance to intergranular corrosion as compared with other SS grades. The grade is highly exposed to high temperature in the chromium carbide precipitation environment. Grade 347 gets stabilized by the addition of columbium and tantalum. The grade exhibits good pitting resistance, crevice corrosion resistance and stress crack corrosion resistance.
Alloy 347H is the higher carbon version of the alloy that offers great traits for manufacturing high quality of coil tubings material products. The characteristics exhibited are high resistance to corrosion, good oxidation resistance, pitting resistance to chloride environment, stress crack corrosion resistance and excellent strength and toughness at high temperature and pressure.
