Description:

Duct is built of the aluminium laminated with the polyester. It was designed especially for the needs of the ventilation and air conditioning market.
It has the advantage of no need to use special tools for cutting or fixing, it does not emit toxic gases in high temperatures. it is fire resistance.

Technical specification:

Insulation Products/Fire-Resistant And Explosion-Proof PVC Flexible Duct

Q: Drain flexible pipe to keep the base design above the elevation of the number of meters: Fourth, the internal structure of the flexible pipe joints and KRJ internal structure is slightly different, flexible pipe joints without back Taiwan or small back out of the station, while the latter is the big back five, flexible pipe fittings standard clamp type flexible pipe fittings disassembly Of the time can be used grinding demolition, shoulder type flexible pipe joints can not Note: Some units on the market now mix these two products, the purpose is to sell low prices for low-priced products, so you can get more profit margins To ask for the data parameters of the drawings to determine whether the flexible pipe joints or flexible pipe joints

Q: Do you have a natural gas hose in the flue?: Look at where, install and dismantle about a total of 50 yuan a square it The activities of the activities of the Central Chamber of Commerce Co

Q: Flexible pipe trench backfill inspection batch quality acceptance record how to fill: Go to the site to run you may have a harvest; The The The The

Q: Safety evaluation: gas pipeline and discharge pipe should not be set between the valve, what is the specification of which provisions?: 028W / MK) and enduring excellent insulation and compression performance, compressive strength up to 220-500Kpa

Q: How is the flexible casing of the fire pond connected to the tube?: EPS expansion polystyrene board: is a volatile liquid blowing agent containing polystyrene (eps) beads, preheated by heating after the mold in the mold, with fine closed-cell structure characteristics

Q: Why should the flexible hose be set in the mechanical ventilation system?: Bowl buckle price is high! There are many buckle-style markets, so rent up cheap!

Q: CAD type too much (including civil engineering, interior spring design, motor, machinery manufacturing and many other), a beginner how to choose?: The concrete structure has been included in the structure, but the concrete structure is a concrete structure, but the structure is just a frame structure without concrete structure; another steel structure and concrete structure is a good idea but to do Less, the third floor is said to be the main structure of the original structure, masonry works using concrete, then this will undoubtedly increase the cost of the house, if not very high floor or earthquake area is clearly not economical

Q: The first generation of the tube is that year out?: Are flame retardant, one is benzene board, one is extruded board. Extrusion board is the latest in recent years, the rise of the new insulation sheet, relative to the benzene board, its advantages are: recyclable, can effectively solve the white pollution; physical foam, the production of small harm to the human body ( Benzene is a chemical foam harmful to the human body). Flame-retardant effect and insulation effect is stronger than the benzene board, divided into: B Mangchuan Cao boiling 丨 degree check sand sausage 1 750 or so, B2 level 550 yuan, (B1 flame retardant effect is flame retardant, B2 is relatively poor) Benzene board than the extruded board of various orders cheaper about 200 yuan

Q: What is the difference between the D-LD2000 clamp-type flexible fittings and the KRJ-type clamp-type flexible fittings?: Polystyrene board in the basement wall from the role of waterproof protective layer is to prevent the backfill due to external forces on the destruction of the waterproof layer. That the use of multi-layer board bear two Cao Dutch 丨 sell Zhatai Chun Jun can not. Because the deformation capacity of polystyrene board is relatively large. And the deformation capacity of the multilayer board is small.

Q: Plastic tube most afraid of what the East unitary: The bonding strength of the gypsum board and the extruded polystyrene plate is ≥010MPa, and the interface is in the extruded polystyrene board The bond strength of the bonded gypsum and the composite plate is ≥010MPa The combustibility of the composite plate reaches B1 level Construction technology points: the installation of the board between the natural close (including the long board) does not leave; for long board, should be installed before the hardening of the bonding material can be carried out; per square meter composite board with at least 2 Expansion of the anchor, each commonly used specifications of the composite board at least 6 expansion anchors evenly anchored to the grass-roots wall; external walls and internal wall connection should be extended to the wall, the width should not be less than 300mm; And wall bonding area ≥ 30% Applicable conditions and scope: hot summer and hot summer and warm winter area outside the building insulation works
