170Y structured packing customer order service 304 / 316L metal plate
1. 170Y structured packing working theory,
Through the packing, the two-phase flow is upward and downward convection. Gravity is the driving force of liquid flow, and pressure difference is the driving force of gas flow. The two phase flow is mass transfer and heat transfer through the two forms of film surface and spray. The mass transfer and heat transfer of the two phases in the plate column take place in the gas-liquid mixed phase on the upper surface of the tray, on the liquid layer surface of the downcomer and on the bubbling area caused by the mass transfer elements.

3. Hualai Factory 170Y Structured Packing Capacity:
Hualai has years of engineering experience with a variety of structured column packings in different industrial applications. Moreover, we have frequent co-operations with famous universities and technical engineering companies in China.
Resulting from these valuable assets, we have produced range of structured packings suitable for engineering systems that provide optimum column performance.
Hualai structured packing uses the industry standard corrugated perforated and embossed sheet metal design to provide efficient vapour-liquid contact. The style of the embossed surface has been optimised to provide maximum wetability and numerous perforations enhance cross mixing of the process fluids. Type Y has a crimp angle of 45° and type X 30°. Suitable liquid irrigation range from below 0.5 up to 200 m3/m2.hr.
