It is understood that after using the high vacuum welding fume purification system and displacement ventilation system developed by Jiuyuan Company, the average dust concentration in the workplace air is significantly lower than that when not used. The technology is also suitable for manual welding and semi-automatic welding in the shipyard welding shop. CO2 protection welding, welding line, plane segmentation line and other work stations play an active role in reducing welding smoke pollution in the workshop and ensuring the occupational health and safety of welders, with good environmental, economic and social benefits. The technology proves that the treatment device has a significant effect on the welding fume treatment in the welding fume treatment engineering practice of the workshop component welding workshop of Dalian Shipbuilding Industry Group Co., Ltd. The high efficiency of the welding process of the high vacuum welding fume purification system in the project is 98.2%. The catching efficiency of the mouthpiece is up to 93.6%.
Up to now, Jiuyuan Company has completed the welding fume treatment work of the component welding test in the large ship company, and the welding fume treatment in the curved surface welding workshop, and completed the preliminary welding fume treatment plan in Qingdao Beihai Shipbuilding Heavy Industry Co., Ltd. In addition, a number of companies under the CSIC Group have also contacted the Jiuyuan Company to express their welding fume treatment.
Bolt Bonnet Gate Valve with ASME, DIN, GOST or EN standard is the best popular type shut off valve in any kind of low pressure industrial pipelines, Class 150(PN16) to Class600(PN100) matching valve size from 2"(DN50) to 40[(DN1000), which can be operated by electric actuator or handwheel. Bolt bonnet Gate Valve normally with flange ends connection with industrial pipeline as well as welding ends. Valve material can be carbon steel, stainless steel, alloy steel or special steel according the requirements of the working medium.
