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.The tray height of stainless steel orifice corrugated packing is
40-250mm, and the common tray height is 100-200mm. The relationship
between tray height and tower diameter is shown in the following
table. The tray height can be selected according to the tower
diameter and design requirements.
| Tower I. D. mm | 100-400 | ＞400-1000 | ＞1000-3000 | ＞3000 |
| Tray height mm | 40-100 | 100-150 | 150-200 | 200-250 |
The popular tray height is 100mm, 150mm, 200mm. Other heights can
be negotiated.
4. Material
SS304, SS316L, others as per order.
5. Manufacturing requirements
5.1 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.
5.2 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.
