1.6Y Custom Structured Packing plate thickness 0.1mm 0.12mm 0.15mm
1. Stainless Steel Perforated Plate Corrugated Packing
This standard is prepared by the national chemical engineering
design technology center station organized by China Petroleum and
Chemical Engineering Survey and Design Association. In the process
of compiling, the author compared the foreign corrugated packing
with the stainless steel corrugated packing produced by the
domestic manufacturers in the technical level of structural
dimension, characteristic parameters and manufacturing process, and
worked out the standards suitable for the actual industrial
situation.
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.
2. experiences in making structured packing
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.

4. Function of structured packing in distillation column
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.
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!
