Double sealed flexible waterproof casing seal leak problem is always the pursuit of chemical equipment, it is this requirement led to shield pump magnetic pump and expanding applications. But truly no leakage is still a long way to go, life issues such as magnetic pump shield pump shield isolation kits and sets, pitting the material requires corrosion-resistant material sealed, static seal and other reliability issues and so on. Double sealed flexible waterproof casing as follows: 1. Seal type: for static sealing is usually only two forms of gaskets and seals, and O-ring seals again the most widely used; for dynamic seals, chemical pump it less packing seal, mechanical seal mainly mechanical seals have a single face and double face, balanced and unbalanced type of points, balanced for high pressure sealing medium (usually refers to a pressure greater than 1.0MPa), double-end machine seal is mainly used for high temperature, easy to crystallize, the viscosity, containing particles and toxic volatile media, double-end mechanical seal should seal barrier fluid is injected into the cavity soft rubber joints, the pressure is generally higher than the medium pressure 0.07 ~ 0.1MPa. 2. sealing materials: chemical pump static sealing materials commonly used fluorine rubber, special circumstances the use of PTFE material; material configured static ring of the mechanical seal is more critical, not just the best carbide cemented carbide, high prices on the one hand, no hardness difference between the two is also unreasonable use of soft rubber joints, so the best treatment based on the characteristics of the difference between the media, the seams pipeline soft rubber joints rigid waterproof layer and gables, parapets and roof structures with prominent are should do (flexible sealing) process. Double sealed flexible waterproof casing sealing material: Performance of the sealing material is an important factor to ensure effective sealing, choose the sealing material soft rubber joints photograph, mainly based on the sealing element working environment, such as temperature, operating pressure, operating medium used and movement and so on. Yanshan County Bo Yan Pipe Co., Ltd. mainly produces steel seamless pipe fittings, steel pipe joints, forged fittings, flanges and other forged products pressure piping components, products widely used in petroleum, petrochemical, power, heating , shipbuilding, construction, oil and gas and other industries, the best-selling domestic 29 provinces, municipalities and autonomous regions, and exported to the United States, Singapore, Iran, Pakistan and other countries and regions, is the focus of pipe production supply Sinopec, PetroChina, CNOOC, the state electricity and other units providers. What structure and principles of insulation joints are? Monolithic insulating joints of the parts from the following components: the upper and lower tubes, sleeves, insulating parts, seals, insulation coating. Joint on insulation, the down tube butting end face, sandwiched insulation and seals form a double seal structure having insulating properties. Sleeve groove weld or use two forms directly on the catheter and welding, the insulating member and the upper and lower pipe wrap securely sealed to form a "sealed containers", which not only ensures good insulation effect, but also greatly improve the insulation bearing capacity of the structure.
