Explosion-proof flexible connection pipe is suitable for flammable dust environment 20,21,22 zones and IIBIIC class T1-T6 Group explosive mixture site, it is used for connecting the entrance and exit lines of explosion-proof electrical equipment or places where the wiring of steel pipes is difficult to bend. The two ends of the flameproof flexible tube structure hose are metal thread joint, the tube body is composed of metal hose, high-quality rubber and reinforced nib hose jacket, and sandwich steel wire braided net pipe. This product has fire-resistant, oil-resistant, corrosion-resistant, water-resistant, wear-resistant, aging-resistant, flexible, solid structure, reliable work and other advantages, generally 500,700,1000 length. Scope: 1. Apply to Area 1 and Area 2 dangerous places.
Suitable for IIA, IIB explosive gas environment;
3. Suitable for combustible dust environment in 20,21 and 22 zones.
4. Suitable for explosive gas mixing temperature: T 1 ~ T 4; 5. Widely used in oil exploitation, oil refining, chemical, military and other dangerous environment and offshore oil platforms, tankers and other dangerous places for work and scene lighting purposes; Rubber tube explosion-proof flexible connecting pipe, stainless steel explosion-proof flexible connecting pipe, plastic explosion-proof flexible connecting pipe, features: 1, with fire-resistant, corrosion-resistant, water-resistant, anti-aging, good flexibility, solid structure, reliable and other advantages. 2, flexible tube length, thread size can be according to the needs of special processing. NPT thread, metric thread, etc. . Note: internal and external threads should be noted when marking thread specifications. For example: BNG-700 × G 3/4(inside)/g 1(outside) means a rubber sheathed flexible connecting pipe with length of 700, one end of internal thread G 3/4 and one end of external thread G 1. 3. Meet the requirements of GB3836-2000, IEC 60079. When purchasing and marking thread specifications, it should indicate internal and external threads, such as NGdII-1000 × g 3/4”(internal)/g”(external) , i. e. length of 1000mm, g3/4” internal thread at one end and G1” external thread at the other end
