• How globe valves work

    The shut-off valve only allows the medium to flow in one direction, and it is directional during installation. The structural length of the globe valve is longer than that of the gate valve. At the same time, the fluid resistance is large. During lon...

  • What is the essential difference between chemical grade PVC pipe fittings and PVC pipe fittings

    Polyvinyl chloride is made from acetylene gas and hydrogen chloride, and then polymerized. Has higher mechanical strength and better corrosion resistance. It can be used to make exhaust gas detoxification towers and gas-liquid conveying pipes in chem...

  • How to use PVC double-acting ball valve

    PVC chemical valve is a main accessory to control the flow of media on chemical pipelines. For specific principles and structural cross-sectional views, refer to relevant material books. The valve consists of the valve body, the opening and closing m...

  • Performance, material, use and characteristics of pvc pipe

    The material tube is generally made of plastic resin as a raw material, added with stabilizers, lubricants, etc., and is extruded in a tube making machine by a plastic method. Because it has the characteristics of light weight, corrosion resistance, ...

  • Advantages and disadvantages of PPC, PVC, PPR three pipes

    PVC pipe—Polyvinyl chloride pipe can be used for water supply and drainage systems. PVC pipe connection is glued for easy installation, but because of its hard texture, PE and PPR pipes are easier to crack and have poor heat resistance. The cost of P...

  • Whether plastic pipes belong to the chemical industry

    Plastic pipes are an important branch of many components of chemical building materials. The application fields of plastic pipes are usually water supply, drainage, gas, floor heating, power communication, agricultural, fire protection and other fiel...

  • How to set the sampling valve of high pressure pipeline

    Sampling valves, as the name suggests, are valves used to obtain media samples for chemical analysis. They are roughly divided into the following types: double opening valves, flange clip valves, and sampling valves with insulation jackets. Use atten...

  • Valve knowledge

    1. Difference between gate valve and globe valve: Both can be turned off, and flow adjustment can be performed in situations where flow linearity is not high. However, due to the structural characteristics of the globe valve, the flow resistance is l...
