    Pipe Insulation Joint DN20 PN1.6MPa 20#

    Insulating joint is a general term for pipe joints that have both the sealing performance, strength performance and the insulation performance required for electrical corrosion protection required for buried steel pipelines. It contains assemblies, insulating plates, packing, sealing rings, short pipes, etc.


    Category:Pipe fittingsName:Insulated joint
    Specification:Complete specificationsCustom made:Support customization
    Length:Can be customizedOrigin:China Mainland
    Purpose:Drainage system, ventilation system, construction project, water treatment plant, etc.

    Introduction

    Insulating joint is an improved replacement product based on the problems existing in the use of insulating flanges. It is an indispensable and important pressure component in the cathodic protection system of steel pipelines. It is widely used in the cathodic protection system of steel pipelines.


    technical parameter
    Service life: same as pipeline; Applicable medium: suitable for oil, gas, water, chemical raw materials, and ore slurry.


    Structure and principle
    The integral insulating joint is composed of the following parts: upper and lower pipes, sleeves, insulating parts, sealing parts, and insulating coating. Between the butting end faces of the upper and lower pipes of the insulating joint, an insulating piece and a sealing piece are clamped to form a double sealing structure with insulating properties. The sleeve adopts two forms of groove welding or direct welding with the upper pipe. The insulator and the upper and lower pipes are firmly enclosed to form a "sealed container", which not only guarantees a good insulation effect, but also greatly improves the insulation The pressure bearing capacity of the structure.

    Installation requirements
    1. Within 50 meters of the insulation joint installation place, avoid dead holes to be welded;
    2. After the insulated joint is connected to the pipeline, it is not allowed to lift the pipeline within 5 meters of the joint; 3. Test the pressure of the insulated joint with the pipeline instrument.

    Quality requirements


    Insulation strength:2500V 50Hz 1 minute without breakdown or arcing;
    Insulation resistance:DC 1000V resistance ≥6MΩ;
    Hydraulic test pressure:1.5 times the design pressure;
    Air tightness test pressure:equivalent to the design pressure;
    Non-destructive testing:in accordance with JB4730 -94 100% radiographic flaw detection for all butt joints, 100% magnetic particle flaw detection for other pressure-bearing welds;
    Groove:API5L standard.
