Lanzhou Lanluo Refining and Chemical Equipment Co., Ltd.:
After review, your unit is approved to manufacture pressure vessels within the scope of the BR1 pressure vessel license, special issue This certificate. Non-detachable horizontal 90m
Carbon steel blasted rotating plate heat exchanger
Application in the entire petrochemical industry
Two processes, four channels, vertical 360° rotary, 185m detachable Spiral plate heat exchanger
Lanzhou Lanluo Refining and Chemical Equipment Co., Ltd. is a professional manufacturer of spiral plate heat exchangers. The heat exchange area of ??a single unit can reach 400m2. Due to the high efficiency of the spiral plate heat exchanger, under the same working conditions of water-water convection heat transfer, the heat transfer efficiency is 50% to 100% higher than that of the tube type heat exchanger. It has strong self-cleaning ability, is not easy to get clogged, and has small heat dissipation loss. , small heat transfer temperature difference, compact structure and other advantages, it is very popular in many industries. The company has established a Class III pressure vessel manufacturing company
with a complete quality management system and holds
certificate. It has provided more than 2,000 spiral plate heat exchangers to oil fields, refineries, chemical processing, metallurgy, heating and electric power industries. In addition to spiral plate heat exchangers, head heat exchangers, plate heat exchangers and fin tube air coolers are also available to me! Want products.
