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:Maintenance Skills of Leakage of Fire Pipe Clamp Joint
On the use of steel pipe rack (double pole) support, the specific step to be self-checking, if it is 9 meters high, should be taken out of the full frame, the middle of the spine set must be standardized, in fact, we usually do high-level conversion layer beam is very common You share the board as a beam {face - line load}. On the line is not very complicated. Circular arc positioning to be accurate, first to do stereotypes better.
Q:Cast iron flexible tube A type B What is the difference
Air conditioning duct glass wool insulation loss is generally between 1
Q:The sound of water pipes will not produce infrasound damage to the human body?
The first look at the factory declaration materials in the building level. The second depends on the material you use sandwich panels. (Generally Caigang sandwich rock wool no problem, glass wool depends on the design requirements of the building).
Q:Heating pipe through the deformation of the joints, the album is written on the "metal hose", the problem one: This is a flexible hose? Question 2: how to set the quota
Air conditioner is the air temperature, humidity, purity, air speed, for processing, to meet people's production and living needs of the equipment, referred to as air conditioning
Q:What materials are made of flexible pipes? Why should the mechanical ventilation set the flexible tube? Where should I be located?
It is recommended to use the home of the heart of the card to worry about toughness to fill the joints, and then paste the seam (master understand) if directly in the sandwich panel (plate) on the batch of putty powder or spray painted really easy to drop off the phenomenon of stone, the first primer, it is recommended to use the home of the German brand brackish scraping scraping again There are), to be dry and then approved scraping putty powder spray really stone paint
Q:Plastic tube most afraid of what the East unitary
In general, polyurethane sandwich panels can be used in a variety of building needs, including industrial plants, public buildings, combined housing, purification projects and other construction areas
Q:Where there are wear-resistant tube, high temperature ceramic tube
The fraction of 200 ℃ in the condensed product was analyzed by GC-MS, and the degradation phenomena and products were discussed
Q:Can the kitchen sewage pipe pass through the walls of the stove wall?
The system can avoid the hot bridge in winter, greatly reducing the indoor heat loss through the external walls; summer can greatly reduce the external radiation from the sun to the indoor heat conduction, and thus the heating, air conditioning energy consumption decline
Q:The first generation of the tube is that year out?
It is made up of corrugated flexible tube, net cover and joint Metal hose with austenitic stainless steel or according to user requirements of the material manufacturing, metal hose has excellent flexibility, corrosion resistance, high temperature resistance (-235 ℃ ~ +450 ℃), high pressure (up to 32MPa) , Metal hose in the pipeline can be connected in any direction for temperature compensation and absorption of vibration, reduce noise, change the direction of media transmission, to eliminate the pipeline or between the pipe and the mechanical displacement between equipment, double flange metal corrugated hose It is particularly suitable for flexible joints with various pumps, valves and so on for displacement and vibration Metal hoses use two kinds of bellows, one is a spiral corrugated tube; the other is a ring bellows Solution: Songjiang metal hose
