250Y SS316L 800mm Diameter Metal Structured Packing
Uniform Liquid Distribution
In order to achieve even liquid distribution over the packing it is a must to have a good liquid distributor to maximize the interaction of the liquid and vapor. However if the packing height exceeds 3 meters we recommend using an intermediate liquid re-distributor as well for even flow.
Fixing and Installation
It is a very basic and simple procedure. Once we have optimized the dimensions of the packing we must ensure that the inside of the column is clean and has no weld joints or bulges to obstruct the installation. The supporting structure can be made of two cross bars at 90 degrees to each other and in larger columns the same construction must be repeated at a pitch of 150mm.
Once the support is in place, successive modules of structured packing must be inserted from the top - down. Normally a wooden disc (having a slightly small diameter than the packing) is mounted on a pole and used to push each segment down to their position due to the very narrow diameter of the column.
Surface Treatments of Sheet Metal Structured Packing
It is important to achieve good contact between the liquid and vapor phases. A packing that spreads the liquid evenly in a thin film will exhibit beter performance. Mixing the film creates turbulence that enhances the mass transfer.
Modifications to the texturing of the packing surface improve the liquid spreading which, in turn, leads to enhanced packing efficiency.
All types of structured packings are available in a variety of corrugation sizes. This provides the versatility needed to optimize a packing configuration to best meet the efficiency, capacity, and pressure drop requirements for a particular application

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. 316L Stainless Steel 450Y Distillation Packing Capacity:
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.
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.
Worldwide Shipping
every year we manufacture and supply hundreds of cubic meters of metal structured packing in different models. There are many popular types and materials for option. Custom order is welcome, too! We are happy to help with what you need!
