YUHONG Group deal with Austenitic Stainless Steel, Nickel Alloy Steel(Hastelloy , Monel, Inconel, Incoloy ) seamless and welded pipe and tube already more than 32 years, every year sell more than 80000 tons of steel pipe and tube.

Our client already cover more than 65 countries, like Italy, UK, Gernany, USA, Canada, Chile, Colombia, Saudi Arabia, Korea, Singapore, Austria, Poland, France , ....

And our group branch company and factory have been already approved by :ABS, DNV, GL, BV, PED 97/23/EC, AD2000-WO, GOST9941-81, CCS, TS, CNNC, ISO9001-2008, ISO 14001-2004.

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.
