The three major heat transfer equipment widely used in the petrochemical and natural gas industry are plate heat exchanger, plate shell heat exchanger and semi-welded plate heat exchanger. The petrochemical and natural gas industry is the representative of China's basic industry, in which the liquid phase, vapor phase media changes and product heating, cooling, condensation, evaporation and other aspects, there are our three major heat transfer equipment.

One of the equipments for the petrochemical and natural gas industry in Qingdao Ruipute is the plate and shell heat exchanger. It consists mainly of external objects as well as internal plate packs. The plate pack is made up of corrugated metal sheets welded together in a circle according to the hole, and the circular plate pack has a more uniform stress distribution than the square plate pack. Liquid-liquid, gas-liquid, gas-gas and other heat transfer processes are widely used in the petrochemical and natural gas industry, and can be applied to heaters, evaporators, condensers, coolers, etc.

The second equipment in Qingdao Ruipute is the detachable plate type heat exchanger for the petrochemical and natural gas industry. Qingdao Ruiput can produce more than 200 kinds of plates, with different corrugations, depth, spacing, thickness and so on to meet the needs of a variety of working conditions. The use of special materials such as titanium, titanium palladium, hastelloy and other special materials can solve some of the corrosion problems and are widely used in the petrochemical industry. The use of professional selection software to ensure scientific selection and the use of precision machining presses ensure a high level of product quality.

Qingdao Ruipute petrochemical and natural gas industry application heat exchanger equipment of three:semi-welded plate heat exchanger. Its construction features two plates welded together to form a pair of plates, which are sealed with a sealant strip between the plates to form a separate flow channel. At present, it is more promising for the development of high temperature and high pressure media and corrosive petrochemical conditions, can be widely used. Safety has been greatly improved.

 Qingdao Ruipute's three major heat exchangers are widely used in the petrochemical gas industry, proving the importance of energy saving and environmental protection in the petrochemical industry and the high quality of Ruipute's heat exchangers from the side.
