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.
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.
