Materials	1.inner work steel	Seamless steel pipe for steam Impeller blasting and paint before insulation Standard of GB/T9823-1988 and level Sa2.5
	2.aluminium silicate fiber felt(drag reduction layer)	Be put between inner work and inorganic insulation (to insure the steel pipe movement when expansion and contraction)
	3.calcium silicate insulation material	Can be customed into glasswool,rock wool,ect Use break strapping, and filled foam asbestos in the cracks to reduce heat lossing
	4.aluminum reflector	To prevent the inorganic insulation foam from going into the insulation material Prevent heat loss and make the steam pipe is more economic
	5.polyurethane insulation layer	Good effect of heat insualtion
	6.outer work steel	GB/T9711.1Spiral weld pipe or SY5292ERW pipe
	7.outer anticorrosive coating	3PE anticorrosion

Rock wool is a mineral inorganic fibrous material with excellent and distinguished properties and characteristics. It is efficiently applied in all fields of thermo-acoustic insulation; furthermore it is used in many industries and agricultural activities. It is water proof rock wool.

Q: What are the properties of fire-resistant coatings for steel structures?: Ultra thin structure fire retardant coating refers to the coating thickness of 3mm (including 3 mm) less than, decorative effect is good, high temperature can expand foaming, fire-resistant limit is generally less than 2 H steel structure fire retardant coating. This kind of fire retardant coatings for steel structures is generally solvent system, bonding strength, weathering has good water resistance, good leveling, good decorative features such as superior; subjected to fire slow expansion foam fire insulation layer to form a dense solid, the fireproof layer has a strong impact resistance, the temperature rise of steel delay, effective protection of steel member. Ultra thin intumescent steel structure fire retardant coating can be sprayed, brushed or rolled. It is generally used in building steel structures with a fire resistance requirement of less than 2 h. At present, there has been a fire resistance to meet or exceed the new ultra-thin fireproof coating for steel structure of 2 varieties of H, it is mainly based on the special structure of the poly methyl acrylate or epoxy resin and amino resin, chlorinated paraffin, compound as base adhesive, with high degree of polymerization of ammonium polyphosphate, melamine and pentaerythritol, double as the fire retardant system, adding titanium dioxide, wollastonite and other inorganic refractory material, using 200# as solvent and solvent oil compound. At present, all kinds of light steel structure, grid and so on, use this type of fire retardant coatings for fire protection. Because this type of ultra-thin fireproof paint coating, making use of thick and thin fire retardant coating for steel structure is greatly reduced, thereby reducing the total cost of the project, the steel structure has been effective fire protection, is currently promoting varieties on the market.

Q: Which is better, roofing rock wool or glass wool?: Glass wool than low density rock wool, slag ball less content, low thermal conductivity, long service life, high toughness fiber, but the maximum use temperature of high rock wool up to 600 degrees Celsius, glass wool is only 260 degrees celsius.

Q: What are the advantages of inorganic fiber spraying in construction engineering?: Inorganic fiber spraying is a new type of environmentally friendly architectural coatings, mainly composed of inorganic fiber and water-based adhesive composition, by mixing by air pressure pump for spraying, spraying and atomized water mixed to form coating on the substrate to protect. The coating can meet the requirements of sound absorption, thermal insulation and fire protection.

Q: The difference between rock wool and mineral wool: By the above two concepts, we should compare the difference between rock wool and slag cotton.1., raw materials are different: to metallurgical slag or fly ash as the main raw material called slag cotton; basalt and other rock as the main raw material called "rock wool"".2. the coefficient of acidity of rock wool and slag cotton is also different. Rock wool acidity coefficient MK generally greater than 1.5, and even up to more than 2; slag cotton MK generally can only be maintained at around 1.2, it is difficult to more than 1.3.3. because of the difference between chemical composition and acidity coefficient of rock wool and slag cotton, they also show some differences in performance.(1) the difference of water resistance(2) difference of heat resistance;(3) difference in corrosion resistance

Q: What are common house thermal insulation materials?: In architecture, it is customary to control the flow of heat through the houseMaterials called thermal insulation prevent the heat from entering the room from being called heat insulation material. Insulation, thermal insulation materials insulation materials called duncan. The commonly used insulation materials can be divided into two categories: organic and inorganic. In its shape

Q: What are the building thermal insulation materials in general?: Building thermal insulation material is to take measures to reduce the heat inside the building to the outside, so as to maintain the indoor temperature of building. Building insulation material plays an important role in creating suitable indoor thermal environment and saving energy in building insulation.

Q: Does water paint spray fire in underground space?: Waterborne paint itself is waterproof, unlike oil paint as security for.

Q: What material is fast heated and kept warm?: Heat the heating tube and the aluminum tube with the heat preservation material.There are many kinds of insulation products, including foam plastics, mineral cotton products, foam glass, expanded perlite thermal insulation products, rubber powder, EPS granule insulation paste, mineral spraying cotton and foamed cement insulation products.

Q: What are the types of insulation materials used in pipes and equipment?: In buildings, materials used to control the flow of heat inside the building are called heat insulation materials, and materials used to prevent outdoor heat from entering the room are called heat insulation materials. Insulation, thermal insulation materials insulation materials called duncan. The commonly used insulation materials can be divided into two categories: organic and inorganic. According to its shape, and can be divided into fibrous, porous, microporous, bubble, granular, layered and so on, the following are some of the more common materials are briefly introduced.

Q: Fireproof rock wool board can be used as firewall?: Rock wool board mainly by hydrophobic rock wool board pendulum method for production of insulation layer material, composite rock wool board is the natural rocks such as gabbro, Xuan Wuyan, dolomite, iron ore, aluminum and vanadium as the main raw materials, inorganic fiber adding binder, hydrophobic agent by high temperature melting, made of fiber the implementation of standards, GB/T25975-2010 is "building exterior insulation rock wool products"; rock cotton in the industrial slag blast furnace slag such as slag, phosphorus slag and fly ash as the main raw material, inorganic fiber after remelting fibrosis made. This paper introduces the main A-fire exterior wall external insulation system on the market (the following text from Chinese architectural design and Research Institute of standards "exterior insulation construction" Standard No. 10J121) the implementation of standards is GB/T11835-2007 "insulation rock wool, slag wool and their products".
