  • Soft Joint Flange

    Soft Joint Flange

    High quality soft joint flange is offered by China manufacturer SN Valve. Soft joint flange usually consists of a pair of flanges, a soft joint (e.g. made of rubber, plastic or other elastic materials) and a number of bolts and nuts. The soft joint sits between the two flanges and acts as a seal and cushion. This type of flange connection through the bolts and nuts to the two flanges closely clamped together, and use the elastic deformation of the soft joint to compensate for the piping system displacement, vibration and temperature changes and other factors caused by the stress.

  • Rubber Flexible Joint Flange

    Rubber Flexible Joint Flange

    The rubber flexible joint flange is a part used to connect pipes and equipment together. It consists of two parts: a flexible rubber joint and a flange. Rubber flexible joints are usually made of rubber materials and have good elasticity and sealing properties. In addition, they can also absorb the vibration and displacement of the pipeline to protect the pipeline from damage. On the other hand, a flange is a metal part used to connect pipes or equipment, with one or more protruding edges (i.e., flange faces) for bolting with other flanges or parts.

  • Socket Welded Flange

    Socket Welded Flange

    As the professional manufacturer, SN Valve would like to provide you high quality socket welded flange. Socket weld flange is a flange in which the end of the pipe is inserted into the step of the flange ring and welded at the end and outside of the pipe. It usually consists of flange body, bolt holes, sealing surface and other parts, and its structural form has two kinds of necked and non-necked. Necked socket weld flanges have good rigidity, small welding deformation and better sealing, so they are more common in practical applications.

  • Importance of tube sheet anti-corrosion and how to prevent corrosion?

    Tube sheets are mainly used in chemical containers, such as shell-and-tube heat exchangers and seawater desalination, to support and fix the tubes. The metal material makes it not only very rigid, but also has great thermal conductivity. In its use, tube sheet anti-corrosion is a very important task. Why is this?

  • What are the advantages of Copper Alloy Tube Sheet?

    Copper Alloy Tube Sheet plays a crucial role in industrial production and equipment manufacturing due to its outstanding advantages such as strong rigidity, excellent thermal conductivity, wide application, and the impact of machining accuracy on equipment performance.

  • Do you know why the gasket on both sides of the tube sheet must be made of the same material?

    The tube sheet is on both sides of flange fastening bolts, they are the same bolts, and the pressure on the gasket on both sides of the tube sheet is the same, and they are under force at same time.

  • How much do you know about tube sheets?

    In the complex systems of heat exchangers, boilers, and filtration systems, tube sheets are essential components that determine efficiency, safety, and service life. Often described as the backbone of these systems, tube sheets are precision-engineered sheets, typically round in shape, drilled with precisely aligned holes that support, separate, and seal the tubes. As a leading manufacturer in China, SN Valve specializes in advanced engineering and produces high-quality tube sheets that meet the most stringent industry standards.

  • Why Is Socket Weld FLANGE Essential for High-Pressure Piping Systems?

    In industrial piping systems where reliability and pressure resistance are critical, choosing the correct flange type directly affects system safety and operational efficiency. Among the many flange types available, the Socket Weld FLANGE is widely recognized for its strong structural performance in small-diameter, high-pressure pipelines.

  • Why is the Demand for Plate FLANGE Soaring in High-End Manufacturing?

    In recent years, high-end manufacturing sectors—including aerospace, energy, and precision machinery—have seen a significant surge in demand for Plate FLANGE components. This trend is driven by the critical need for reliability, durability, and performance under extreme conditions.
