1. Product Introduction
Heat exchanger tube sheet is a kind of round plate, which is used to fix the tube and seal the medium in the heat exchanger. Heat exchanger tube sheet is a kind of fitting which can weld and fix the pipe. The clad tube sheet we provide can achieve the effect of saving resources and reducing costs without reducing the use effect (corrosion resistance, mechanical strength, etc.).
The investigation on the stress corrosion of stainless steel heat exchangers used in oil refineries was carried out in Japan. The results showed that the proportion of stress corrosion of fixed tube sheet heat exchangers was 65%, which was higher than that of other types of heat exchangers. In order to prevent the occurrence of stress corrosion, 316L / SF45 stainless steel clad steel plate was used for the tube sheet of heat exchangers.

5.FAQ
What are the main application areas of metal clad laminates
1.Petrochemical Industry: 0Cr13 (sus410), 0Cr13Al (SUS410S), 0Cr17 (SUS430), 0cr17al (sus405), SUS321, SUS316L and other stainless steel / steel clad plates are mainly used in oil refining, and a large number of corrosion-resistant materials are selected according to the quality of crude oil. Middle East crude oil has high sulfur (s), and 0Cr13 (sus410), 0Cr13Al (SUS410S), 0Cr17 (SUS430) are mostly used; PTA plants in chemical industry are large and large Titanium / steel composite plate is used for the main body, which is in the period of localization and renewal. Vacuum salt production (300000 tons / year, about 200 tons of composite plate) is now mainly composed of 2205 stainless steel / steel composite plate and titanium / steel composite plate. There are many manufacturers and considerable consumption. The replacement time is estimated to be 10-20 years according to the materials in use.
2. Electric power: the amount of titanium / steel composite plate used for chimney of desulfurization system in thermal power plant is huge, and now it is at the end; titanium / steel composite plate and stainless steel / steel composite plate are used for power plant equipment.
3. Nonferrous Metallurgy: aluminum / steel (aluminum / titanium / steel) composite block electrodes are used in electrolytic aluminum industry, with huge quantity and short renewal period (2.5 years); titanium / copper composite rod (electrode) and titanium / steel composite plate (electrolytic cell) are used in electrolytic copper, nickel, cobalt, etc., with fast renewal of consumables. The autoclave for producing nickel from laterite in hydrometallurgy mainly concentrates titanium and titanium alloy steel composite plates with good specifications (4-10 / 30-110) and large consumption (about 450 tons for one set abroad).
4. Titanium / steel composite plate, stainless steel / steel composite plate and other corrosion-resistant metal materials and composite plates for environmental protection and three wastes treatment.
5. Titanium / steel composite plate, copper alloy / steel composite plate, stainless steel / steel composite plate and other corrosion-resistant metal materials and composite plates for marine engineering
