PTA air compressor unit localization plan first recognized

中化新网讯 扬子石化PTA空压机组国产化方案日前通过了中国石化集团公司组织的专家论证。专家组一致认为,由沈阳鼓风机厂和杭州汽轮机厂编制的空压机组国产化方案合理可行,基本满足扬子石化PTA改造项目工艺技术要求。这是PTA空压机组首次获得认可的国产化方案。


The air compressor unit is the core equipment of the PTA unit. At present, all air compressor units for PTA units in China are imported products. The special process, high price and long delivery time of the unit have always been a major problem that has plagued the production of petrochemical enterprises. In addition, the high energy consumption of imported products has always been the bottleneck affecting the economic benefits of the equipment and even the growth of corporate profits. Several domestic manufacturers have participated in the technical exchange of air compressor units for new PTA projects, but have not been able to obtain equipment localization licenses.


Approved by Sinopec Headquarters, Yangzi Petrochemical has carried out energy-saving renovation of the old PTA plant, and the key to the project is the transformation of air compressor units. Since the approval date of Yangzi Petrochemical, the Sinopec Engineering Construction Company has conducted several feasibility studies on major domestic compressors and steam turbine manufacturers. In the end, the combination air compressor and expansion mechanism and rotor dynamics scheme, steam motion design scheme, unit control scheme and steam turbine design scheme provided by Shenggu and Hangqi basically meet the technical requirements of the Yangzi Petrochemical PTA transformation project and get the experts. Their recognition.

Airless Paint Sprayer

Airless paint sprayer gives a smooth layer of coating over surfaces that is practically impossible to achieve using a brush or roller.

Airless Sprayer has a pump that forces paint up a hose and out of a Spray Gun through a very small tip. The nozzle on the end of the spray gun creates a fan pattern of paint onto a surface.  The tip size, as well as the pressure level, dictates the rate of paint flow.

According to the power type, it can be divided into Electric Airless Paint Sprayer, Gas Powered Airless Sprayers, Pneumatic Airless Sprayers, Hydraulic Airless Sprayers...

HVBAN exported 13 years of airless paint sprayers and original spare parts for Graco / Wagner / Titan.

We will offer kinds of spray paint machines and better after-sales service.
