Hualai 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.
Hualai 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.
Inspection items
1 Each batch of structured packing shall be inspected by the quality inspection department according to the contract before leaving the factory.
2 The appearance of packing plate shall be flat and free of rust.
3 The peak height, wave distance, inclination and tooth angle of the packing shall meet the corresponding standards.
The deviation between the accumulated length of the peak height of every 100 pieces and the accumulated length of the actual product 100 pieces is: the positive deviation is not more than 1h, and the negative deviation is not more than 2h.
4 The diameter, Ovality and levelness of packing disc shall meet corresponding requirements.
5 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.
6 the allowable deviation of steel strip thickness shall comply with the provisions of GB / T 4239.
Structural dimension and characteristic parameters of stainless steel orifice corrugated packing.
