Fertilizer Industry Urea Production Custom 250Y Distillation Packing
1. Distillation Packing Chinese Standard: HG/T 21559.2---2005
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.

3. 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.
