In materials metal hose major parts of the austenitic stainless steel, thus ensuring the hose excellent heat resistance and corrosion resistance, the hose very wide operating temperature range dn125 waterproof casing, is -196-600 degrees hose used by pipelines through the medium of corrosive select the appropriate grades, you can ensure that the corrosion resistance of the hose. 1. The overall use of metal hose made of stainless steel 1Cr18Ni9Ti 02s404 waterproof casing, with strong corrosion resistance. 2. Hose body is thin-walled stainless steel tube hydroforming, with strong flexibility, high scalability, bending and vibration resistance, weaving nets of enhanced protection, so that it has a higher loading capacity. 3. The connection ends of the hose connections can also be made in addition to other threads, flange standard, easy connection and use. Special metal hose 4. The product is suitable not only for supporting the rotary joint waterproof casing, and is widely used to connect a variety of flexible delivery of the fluid medium. Corrosion, high temperature, low temperature (-196 ℃ ~ + 420 ℃), light weight, small size, flexibility is good. Widely used in aviation, aerospace, petroleum, chemical, metallurgical, power, paper, wood, textile, construction, pharmaceutical, food, tobacco, transportation and other industries. Flexible waterproof casing Description: flexible waterproof casing is applied to the pipe through the wall at the close by vibration or water structures required hardware fittings, the general production enterprises are developed based on the design of Building Research S312,02S404 standard drawings set manufacture. Flexible waterproof casing wall at the wall, when in case of non-concrete walls instead of concrete and must be solidified in a casing wall; flexible waterproof casing is widely used in construction, chemical, steel, water, sewage treatment and other units. Flexible waterproof casing classification: According to the standard portfolio can be divided into: national standard and non-standard. GB waterproof casing means 02S404 or 02S312 standard atlas selection and production in full accordance with the Ministry of Construction related to the thickness of the flange, ring wing thickness, diameter and thickness, there are stringent requirements. Non-standard is in the shape of the case and about the structure of standard atlas, when the selection of the thickness of the flange, ring wing thickness, diameter and thickness that the relaxation of requirements, strictly speaking, these are substandard products, of course, must the degree of relaxation of standards within not affect the use, but excessive relaxation of standards affect the return performance. According portfolio can be divided into: S312-type flexible waterproof casing and 02S404-type flexible waterproof casing. In both dimensions, the structure has a different form. Flexible waterproof casing Description: 1. Flexible packing materials: asphalt, flax, polystyrene board, PVC foam board. 2. sealant: polysulfide sealant, polyurethane close to the cream. 3. casing wall at such time in case of non-concrete walls, concrete walls should local switch, its casting range should fly wing to wing ring diameter (D5) Large 200 waterproof casing dn300, and must be fixed to the wall bushing once poured. 4. wear a tube wall thickness at the concrete should not be less than 300, or should make the walls thicker side or both sides of the thickened portion of at least the diameter of the thickened D5 + 200. 5. casing weight to L = 300 calculations such as wall thickness is greater than 300, it should be calculated. dn125 waterproof casing, waterproof casing, Bo Yan Pipe supplied by Yanshan Xian Yan Bo Industry Co., Ltd.
