Features:

-'U' bending is done by cold working process.
-'U' bending is done to the required radius as per customer drawings.
-The bend portion and six inch leg is stress relieved by resistance heating.
-Inert gas (Argon) is passed through it at the required flow rate to avoid oxidation in ID.
-The radius is checked for its OD and wall thinning with the recommended specification.
-The physical properties and micro-structure is checked at three different position.

In a heat exchanger, heat is transferred from one (hotter) material or material flow to another (cooler) one. In most applications operated under steady-state conditions, for heat exchange between fluid flows. External walls are well insulated to avoid heat losses to the environment (except for most air cooling systems).

Steam-to-Water or Water-to-Fluid heat exchangers are used primarily to heat a fluid in the tube bundle with steam or water. Proper installation of control valves, vacuum breakers and steam traps are essential for trouble-free operation of the system. Efficient operation of a heat exchanger requires extracting the maximum heat from the steam. This is accomplished by operating at the lowest possible heat source pressure, and sub-cooling the condensate (in case of steam) after it is drained through the steam trap to eliminate flash steam.

Chemical Composition:

316L Stainless Steel Features:

316L Stainless Steel grade is molybdenum-bearing austenitic stainless steel, 316L is more resistant to general corrosion and pitting corrosion, crevice corrosion than the conventional chromium-nickel austenitic stainless steel such as 304.

316L Stainless Steel also offer higher creep, stress-to-rupture, and tensile strength at elevated temperature. The recommended temperature range includes -425°F to 1,200°F (-255°C to 605°C).

In addition to excellent corrosion resistance and strength properties, the Alloys 316 and 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are typical of the austenitic stainless steel, 316l is often used in marine atmosphere.
