- Q:Does the desulfurization and denitrification equipment use metal hoses?
- You are a few classes in the hospital, ah, I finished up
- Q:Two hundred galvanized pipe should be under the large flexible tube
- Expanded polystyrene board is a common white foam board; this foam board is formed by foaming. The extruded polystyrene board is a color foam board (common colors: gray, blue, yellow, green, etc.); this type of foam is lack of dumplings dumplings. In other words, in addition to color, the production process is the difference between the focus.
- Q:What is the difference between a rigid sleeve and a flexible sleeve?
- The usual insulation materials are associated with the insulation, the choice of insulation materials are usually smaller than the heat, that is not due to changes in the external temperature and dramatic changes in thermal performance can be stable as ever, therefore, the current building commonly used Of the insulation materials to heat insulation mortar and thermal insulation performance classes gnawing rescue to find the majority of silent board, in these two aspects of doing better is the dragon EVB series.
- Q:The sound of water pipes will not produce infrasound damage to the human body?
- The general pipe and pipe material to connect manufacturers to supply matching, so that more to ensure quality
- Q:Find a joint electronic M1.5.4 type ECU application system wiring harness and layout Thank you, anxious! The
- According to the intrinsic composition of insulation materials can be divided into: inorganic insulation materials and organic insulation materials! Fire rating A is a non-burning point with the insulation effect of materials, materials. Class A non-combustible materials have the characteristics of low density, low thermal conductivity, high pressure capacity, convenient construction, economical and durable. They are widely used in thermal insulation materials and industrial industries such as hot pipes, thermal equipment and other industrial piping equipment and industrial buildings And the civil building envelope structure of the insulation, insulation, sound absorption materials. Because of its good thermal stability, and more for the steel structure of the fire protection coating material. Fire rating B1 level is a flame retardant insulation material, is determined according to the fire resistance of the material, in addition, different parts of the material division is also different! Burning performance: refers to the material and / or products in case of fire burning all the physical and / or chemical changes, that is, the fire reaction characteristics. Fire rating B2 is a combustible insulation material also known as flame retardant materials, mostly organic insulation materials, add the right amount of flame retardants. More common for EPS expansion polystyrene board and XPS extruded polystyrene board, that is, we often say that general board. This material is low in ignition and releases a lot of harmful gases during the combustion process. Fire rating B3 is a flammable insulation material, this is more common as the main material of polystyrene foam insulation material, because this material is easy to burn,
- Q:Steel Reinforced (HDPE) Polyethylene Helical Corrugated Tubes Warm-Fused-Belt Is Connected or Bonded with Rubber Rings? Ask what?
- Is the CAD map, find their own materials do not have a
- Q:Is the flexible sleeve of the broken wall used as a second retest?
- There is a staircase in the middle of the tower crane, from the stairs began to climb
- Q:To ask why the use of clamps connected to the spray pipe after the flush again after the water there will be a lot of hook link position leakage phenomenon? Thank you! The The
- The radial force of the seal is far greater than the axial force of the connecting bolts but all the axial force washers 窢 field urging 讵 peculiar aldehyde support, good self-sealing effect by the pipeline through the media rubber ring pressing force pressure more sealing performance of the more pressure to prevent the pressure of the rubber ring to the inner diameter of the tube end of the interface diameter Preload to prevent the media pressure leakage and the blue compared to the higher the pressure of the pipe the more the advantages of the more dangerous the pipe junction at the flexible state of the clamp and the tube between the gap between the clamp clamp a small number of adjacent pipe to allow the corner tube Pipe pipe between the end of the gap to allow the axial shift of the pipeline to adapt to the expansion and contraction of the pipe; pipe interlocking effect reduced 70% mechanical vibration
- Q:Can the kitchen sewage pipe pass through the walls of the stove wall?
- scaffolding pole base with the height must be high longitudinal bar to the lower extension of the two spans and pole fixed height difference should be 1m by slope slope of the vertical axis of the slope should be 500mm single, double Row scaffolding bottom step should be 2m single row, double row and full of scaffolding stand in addition to the top of the top step outside the other layers of each step must be connected with the fastener scaffolding pole connection, lap should be consistent with the column Provisions: the use of connecting rods should be staggered with two adjacent rods should be arranged to set the synchronization within the synchronization within the separation of the two-phase separation of the distance from the distance to 500 mm; each connected to the main node the use of lap joint lap joint should be at 1m and should be used less than 2 rotating fasteners fixed end fastener cover edge to the rod end distance should be 100mm scaffolding Pole top rail bar should be high wall end 1m should eaves mouth 15m
- Q:Why should the flexible hose be set in the mechanical ventilation system?
- The contents of the special construction plan: engineering overview, preparation basis, construction plan; process technology, safety assurance measures, labor plans, calculation books and related drawings.
