Name: DC medium without thrust compensation parameter table
Model: TWB-type, ZTWB type a product description:     Our factory is the production of various types of heat pipe compensator professional manufacturers. This year, ably assisted in the research departments of the support, after several development and testing, production XGG-A, XGG-B-pipe sizing based on the compensator, and finally successfully developed, TWB and ZTWB type, DC medium without thrust compensator, to capture the domestic long and must end the direct flow of media-free thrust technical difficulties, the product fill a gap compensator.     The advent of non-thrust compensator, the compensator is undoubtedly the heat pipe, a breakthrough product forward. It is not only for the compensator opened up new areas of production, more importantly, it will not only solve the pipeline memory medium in the thrust of the fatal weaknesses of the work, but also solve the bypass pipe stress-free thrust compensator too concentrated, medium resistance of the major drawbacks .     Recently in China, producing high-temperature sealing agent LTW, it's temperature 300 - 600 ℃, working pressure is 10Mpa1 limit the high temperature sealing agent factory applied on the compensation, the DC-free thrust compensator, converted into a oiling DC medium without thrust compensator, compensator to solve the long-term work, there minor leakage problems. I plant will LTW heat sealing agent, the high-pressure injection gun with 60Mpa1, the oil injected into the filling room, the room filling with the material and diameter telescopic pipe diameter will be pressed, oil itself is non-capillary, cold thermal expansion there reduction of nature, it would cause long-term work in the compensator, no leakage.     TWB-type and ZTWB Series oiling DC medium without thrust compensator, can be widely used in chemical, petroleum, thermal power, metallurgy, and other urban central heating pipe network, the erection of the pipeline trench and high altitude. At the same time, easy to pipeline design, ease of installation and construction, and save a lot of money (the cost is only a section of mounting bracket 60%). Currently, ZTWB and TWB Series oiling DC medium without thrust compensator, the user prove its superiority has been initially proved superior to other similar products. Second, the principle     that no thrust compensator, is the use of Pascal theory in fluid mechanics, structural design ingenious use of a secret circular steam room, steam room were the two annular pressure surface, a steam room is fixed face, the other is confined in the steam room of the telescopic tube annular shoulder surface, with the telescopic tube is removable. The movable ring and the pressure surface area of just stretching cross-sectional area equal to the compensator work, in the medium under pressure, surface pressure and circular cross-sectional area of the bellows pressure is equal, but opposite direction , so the two pressures cancel each other out. As a result, only considered in the design of stent compression packing friction compensator, the fixation of the thrust calculation, it is no longer calculated by the working medium pressure, caused by the thrust of the mounting bracket. Therefore, fixation is shedding bracket, can save a lot of scaffold material, but also save manpower and financial resources. Third, the main technical parameters and diagrams     (1) Nominal pipe diameter range: DN25-1000mm     (2) applies to the nominal pressure range: PN ≤ 2.5MPa     (3) applies to operating temperature: T ≤ 350 ℃     (4) amount of stretching     (5) Compensation device selection: compensator should be subject to the nominal diameter of DN, the design diameter pipe diameter should be the same table with the parameters, tolerances ≤ 3mm. Choose compensator according to the following examples indicate the type. Note: Material Code: bx on behalf of all stainless steel 1Cr18N19Ti, T on behalf of carbon steel Q235-A, bxb on behalf of a half stainless steel (flexible tube 1Crl8N19Ti) Installation requirements:     (1) and compensation at both ends of the pipe with welded ≥ 6mm wall thickness, it must the groove processing, according to the requirements after welding pressure leak test.     (2) sliding brackets and mounting bracket is designed to install, use ZTWB type, in addition to not counting the working pressure of the thrust, the other the same. To ensure that no lateral displacement of the pipeline, stretching along the axis, the compensator should generally be installed at both ends and slide the bracket oriented in the pipe bend, you must install the mounting bracket.     (3) compensator pipe insulation and protective structures are the same boat, but the telescopic tube telescopic element must not be binding.     (4) the compensator in a variety of environmental temperatures, can be installed by the maximum length of LMax to install, without be stretched or compressed.
