- 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:Find a joint electronic M1.5.4 type ECU application system wiring harness and layout Thank you, anxious! The
- 1.5M is the thickness of the board? If it is, in view of the large amount of concrete from the major, then the long spot of the short spot of the prisoners need to pay special training program reported to the chief engineer or expert approval, which is also the most important [template bearing capacity design calculation], proof of design Of the construction program to meet the bearing capacity of concrete to ensure that the template and its bracket should have sufficient carrying capacity, stiffness and stability, can reliably withstand the weight of pouring concrete, side pressure construction load. In recent years, because the construction of non-standard template led to the collapse of a lot of scaffolding, hope to be cited
- 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:How is the flexible tube of FRP composite pipe defined
- Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor
- Q:Steel Reinforced (HDPE) Polyethylene Helical Corrugated Tubes Warm-Fused-Belt Is Connected or Bonded with Rubber Rings? Ask what?
- Flexible waterproof casing is generally suitable for pipes through the walls by vibration or tight waterproof requirements of the structure; rigid waterproof casing is generally applicable to the pipeline through the walls of the requirements of the general waterproof structures; flexible and rigid waterproof casing Wall of the wall, in case of non-concrete should be used instead of concrete walls, and must be a solidification of the casing in the wall; waterproof casing in the construction, chemical, steel, water, sewage treatment and other units
- 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:Does the desulfurization and denitrification equipment use metal hoses?
- Fire pipe clamp connector leak technical details Detailed: trench-type fire pipe in the use of a long time after the sudden pressure relief occurs after the pipeline displacement caused by leakage of the clamp joints, light with a tight clamp clamp is not necessarily good Effect, because the rubber ring aging, lack of flexibility. The best way to do this is to remove the trench clamp from the inner wall of the trench with a "3mm" thick rubber (available with a thin car inner rubber) with a width of about 2 " ~ 3mm ", cut and then fasten the clamp bolts, water leakage problem is solved.
- Q:Is the clamp type flexible connector connected to the pipe to the rubber pad?
- See the situation, the general 3 percent or so, to see how the management of LZ, hand thank you
- Q:What is the effect of concrete pouring on the construction quality?
- The use of the trench connection to check the pipe sealing surface is smooth, smooth, no burr. Whether the sealing surface of the sealing ring is scratched, whether the length of the sealing section of the pipe meets the requirements. These three points to ensure that certainly not leaking.
- 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.
