Roof insulation layer is extruded polystyrene foam plate how set the amount of set
The honeycomb structure of the thick plate, there is no gap, this closed-cell structure Insulation materials can have different pressures (150-500Kpa) at the same time have the same low value of the thermal conductivity (only 0.028W / MK) and enduring excellent insulation and compression performance, compressive strength up to 220-500Kpa.
Steel structure rock wool sandwich wall panel what the amount of this set
The key indicator of good or bad weight is the weight, that is, the weight per cubic meter. Big enough.
Roofing the top of the extruded polystyrene insulation board generally how much weight ah?
Metal hose is an important connection in engineering technology, from the corrugated flexible tube, mesh sets and joints combined. China in 1993 issued a national standard "corrugated metal hose general technical conditions" (GB / T-93). Metal hoses are made of austenitic stainless steel or according to the material required by the user. It has excellent softness, corrosion resistance, high temperature resistance (-235 ℃ ~ + 450 ℃), High pressure (up to 32MPa), 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 pipe or between the pipe and mechanical displacement between equipment, Lan metal corrugated hose for a displacement, vibration of the various pumps, valves and other flexible joints is particularly applicable. Metal hoses use two kinds of bellows, one is a spiral corrugated tube; the other is a ring bellows. Spiral bellows The spiral bellows is a tubular shell with a corrugated spiral and has a helix angle between adjacent two corrugations. All corrugations can be connected by a helix. Ring bellows Corrugated tube is corrugated closed ring shaped tubular shell, wave and wave from the ring ripple in series. The ring bellows is machined from a seamless pipe or welded pipe. By the processing mode, compared with the spiral corrugated pipe, the length of a single tube is usually shorter. The advantage of the ring bellows is good elasticity and small rigidity. If you need to provide detailed advice, please call 0317-, Xinlong bellows will be happy to serve you.

Scaffolding from the erection of the main points on the scaffolding, cantilevered scaffolding and climbing three. High-level general use of floor and cantilever set of set enough to set the dumplings rush to set off the boat to Long. If the number of layers to more than 30F, and the structure can be relatively simple climbing scaffolding, climbing the advantage of the higher the height of the higher relative to the cost of picking. I am a professional scaffolding company, do not understand can ask me. I hope I can help you.
