316H stainless steel heat exchanger
What is 316H heat exchanger?
A device that basically transfers a specific amount of heat from one fluid to another is known as a Heat exchanger. It can be utilized for both heating as well as cooling processes. The separation of the fluid can be prevented without any mixing. The flow arrangement can be easily classified in parallel flow at the end.
The driving temperature may vary with the position. The stainless steel heat exchanger tubes may be shell heat exchanger tubes or plate heat exchanger.
The stainless steel heat exchanger exhibit features such as improved oxidation resistance, great corrosion resistant, improved stress cracking resistance, crevice corrosion resistance and good strength. These features allow working of the tubes well in the harsh and tough environment. Other properties that make it suitable for demanding applications are high extensive pressure and temperature, and shorter creep properties.
Documentation and quality tests
Various quality tests are been conducted on heat exchangers so as to check the validity of the product. Some of the common tests are hardness test, mechanical test, bend test, IGC test, PMI test, macro test. After these common test, special test like flaring test, flattening test, and third party inspection from professionals.
The documents are nabl test report, legalized certification, attested certificates, raw material test report, and heat treatment charts.
Packaging
The packaging of stainless steel 316H heat exchanger tubes is done in wooden crates, cases, cartons, and boxes with plastic wrapping to avoid rusting while exporting to overseas customers. It can even be customized packed on special demand of client.
One can buy SS heat exchanger tubes at reasonable rates.
