Corrugated Metal Plate Packing 316L Stainless Steel 450Y Distillation Packing
1. 316L Stainless Steel 450Y Distillation Packing
450Y structured packing has higher specific surface area than 250Y and 350Y, so with higher mass transfer efficiency. And moreover, it can be made into M452Y Plus to gain higher flow capacity.
This standard puts forward clear requirements for the structural dimension, material requirements, processing and manufacturing of stainless steel orifice corrugated packing, as well as the inspection method, acceptance rules, product packaging, storage and transportation of the packing.

3. Yuanqiao 316L Stainless Steel 450Y Distillation 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.
