250y 1400mm Diameter 200mm Height 316L metal plate structured packing
1. 250Y metal plate structured packing
250Y structured packing is a kind of general structured packing, and most of the structured packing used in industry belongs to this kind. Corrugated packing is a disk-shaped packing composed of many corrugated thin plates. There are two inclination angles of 30 ° and 45 ° between the corrugated plate and the tower shaft. During assembly, the adjacent two corrugated plates are overlapped reversely. Each tray of packing is vertically installed in the tower, and the adjacent two trays of packing are staggered by 90 degrees.
2. 250Y metal plate structured packing inspection items
Each batch of structured packing shall be inspected by the quality inspection department according to the contract before leaving the factory.
The appearance of packing plate shall be flat and free of rust.
The peak height, wave distance, inclination and tooth angle of the packing shall meet the corresponding standards.
The diameter, Ovality and levelness of packing disc shall meet corresponding requirements.
For the hole diameter d0, hole center distance t and fine grain on the plate, only visual inspection shall be conducted, and the hole shall be free of burr, and the holes and fine grain shall be evenly distributed.

4. 250Y metal plate structured packing in high vacuum distillation column.
Distillation is a method to separate liquid mixture with high purity by using reflux. It is a widely used liquid mixture separation operation in industry, and is widely used in petroleum, chemical, light industry, food, metallurgy and other departments. Distillation operation is classified according to different methods. According to the operation mode, it can be divided into continuous distillation and batch distillation; according to the composition of the mixture, it can be divided into binary distillation and multi-component distillation; according to whether the additives affecting the vapor-liquid equilibrium are added to the mixture, it can be divided into ordinary distillation and special distillation (including extractive distillation, azeotropic distillation and salt-adding distillation); if the distillation process is accompanied by distillation, it can be divided into two types Chemical reaction is called reactive distillation
In the operation of packed tower, the liquid drops from top to bottom along the structured packing surface, and the rising vapor contacts with each other. Therefore, the packing surface is the place for mass exchange and heat exchange.
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!
