Stainless Steel Perforated Plate Corrugated Packing Standard

Manufacturing requirements of 125Y distillation packing

1 According to the requirements, punching, rolling fine grain (or rolling grain equivalent to fine grain) and corrugation of raw stainless steel belt shall be made into corrugation belt of orifice plate, and then the corrugation plate shall be cut into pieces according to different chord length on the cross section of packing plate and the requirements of packing plate assembly or block assembly.

2 The packing plate is composed of a number of corrugated plates arranged vertically and evenly. The corrugation angle of the two adjacent orifice plates is overlapped in the opposite direction.

3 According to the design of tower equipment, the packing plate can be made into a whole plate or block type. The purpose of block type is to facilitate the installation of packing. Each block size shall be able to enter the tower from the manhole for assembly. For towers with a diameter less than 800mm, they can be manufactured as a whole tray or into blocks.

1 General Provisions

1.1 This standard specifies the requirements for marking, specification and characteristics, materials, manufacturing requirements, inspection and acceptance, marking, packaging, storage and transportation of stainless steel orifice corrugated packing products, as well as the calculation of characteristic parameters of orifice corrugated packing.

1.2 The corrugated packing with stainless steel orifice plate is suitable for gas-liquid mass transfer separation tower equipment, and the applicable temperature of the packing is - 200 ~ 400 ℃.

1.3 The structured packing is suitable for the clean gas-liquid system without solid particles or suspended solids or easy to self assemble.

2. Reference standard: GB / T 4239 cold rolled stainless steel and heat resistant steel strip

3.1 Mark

HG/T 21559.2—2005—P×××—×××

Standard No. - year No. - packing model - inner diameter of tower Φ (mm)

For example, the inner diameter of packing tower is Φ 600mm, and p250i type stainless steel orifice corrugated packing is used, which is marked as follows: HG/T 21559.2—2005—P250I—600.

3.2 Specifications and characteristics

3.2.1 Stainless steel orifice corrugated packing is a number of corrugated plates pressed from stainless steel strip, which are vertically stacked and assembled into a disc-shaped structured packing according to the requirements of a certain diameter. The corrugations of the adjacent corrugated plates are inclined in the opposite direction, and the corrugations of the upper and lower adjacent packing plates are 90 ° crossed.

3.2.2 Before the corrugated plate is pressed, it is necessary to punch holes on the plate in advance and press the fine grain, or use the rolling grain equivalent to the fine grain.

3.2.3 Eight types of stainless steel orifice plate corrugated packing are listed in the table. The characteristic parameters of the type selection are the specific surface area of the packing and the angle of the corrugation, which can be selected according to the process design requirements.
