- Q:Composite pipe and flexible tube which aspects of the difference
- Lap is in the concrete structure of the component, the length of steel is not enough, according to the requirements of the two steel will be superimposed on each other and the formation of the connection The basic forms of steel connections are: lashing lap, welding, mechanical connection several categories Scaffold (scaffold) refers to the construction site for workers to operate and solve the vertical and horizontal transport and erected various stents General terms of the construction industry, refers to the construction site used in the external walls, interior decoration or high height can not be directly the construction of the place Mainly for the construction workers up and down work or external safety net enclosure and high-altitude installation components, said white is the shelf, scaffolding production materials are: bamboo, wood, steel or synthetic materials Some projects are also used as scaffolds when the template, in addition to the advertising industry, municipal, traffic, road and bridge, mining and other departments are widely used
- 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:Does the desulfurization and denitrification equipment use metal hoses?

- 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:What is the difference between a rigid pipe and a flexible pipe, what kind of pipe is rigid, what is flexible
