Well-known, metal collapsible tube is the important composition component in cop of join of instantly industry equipment, applied range is wide, the product of metal collapsible tube can use as protection of cable of all sorts of equipment line, transmission wire, fiber-optic cable, producing crucial effect in multinomial domain. So, use metal collapsible tube for better more efficient land, we need to observe relevant use standard, understand its to use a note. The applied limits of will detailed listed metal collapsible tube mixes the article use note, the friend of person of the same trade that gives need is read. Metal collapsible tube of limits of application of metal collapsible tube is the important join component part in project technology, you Bo grain is flexible canal, net is covered and contact is united in wedlock and become. Be in all sorts of is defeated by compensation regards as component of component, sealed component, join and damping component in system of system of pipeline of gas, infusion and length, temperature, position and angle compensation, spin building of electron, the sources of energy sanitation of electron of empty spaceflight of applied Yu Hang, petro-chemical, mine, mechanical shipbuilding, medical treatment, gently to wait for each domain. The newest country standard of metal collapsible tube is " moire metal collapsible tube is general technical condition " (GB/T14525-2010) , carry out at rising on October 1, 2011. 1, armored the electrical wiring protection that cable, accurate and optical feet, optics measures equipment of instrument, medical treatment instrument, machine to use is in charge of applicable and;2, public phone, Yuan Chuanshui the equipment;3 that the other such as warning apparatus of magnetism of watch, door needs to undertake to electrical wiring safety defends. 5, Pvc of solar energy equipment is outer diaphragm. The use note 　 of metal collapsible tube 1.

Safeguard metal collapsible tube to cannot be in daggle of cuting or rough surface, cannot suffer hammer to attack, graduating with cutter, change model, car is ground pressure. Ship heavier straight tube, rise especially proper safeguard should be taken when weighing. 2.

After installation of joint of sealed test metal ends, should undertake hydraulic pressure checks (test pressure comply with is corresponding data) , ensure metallic joint and tube do not have leakage, do not become loose. If do not have living standard to test a standard, pressure checks should place of business of production of comply with tube provides data. 3.

Electrostatic the installation that when releasing installation to have the hose that releases electrostatic function, needs to produce business to set to comply with especially is normative. After metallic interface installation ends, need to have corresponding test. If tube can bear only low resistance, can use access instrument test or insulation controller. 4.

Fixed device secures the tube on device to should take a safety precaution. The safety precaution cannot affect tube to answer the normal deformation that pressure produces, include (length, diameter, bend etc) . If tube needs to bear special and mechanical power, pressure, negative pressure or geometrical deformation, consult manufacturing business please. 5.

Mobile component installs the tube on mobile component, should ensure tube won't be sufferred because of shift bump, block, wear away reach bend out of order, fold, dilatory or it is screwy. 6.

Outside consulting information divides number, if want to add referenced information on tube, should choose appropriate adhesive plaster. Cannot use paint and coating in addition. Tube is outer diaphragm and paint kind solution can produce chemistry. 7.

Safeguard need to undertake basic maintenance to tube by the regulation from beginning to end, ensure tube performance characteristics. Need to notice metallic joint and the certain and specific phenomenon that react tube gets pollution, be like: Normal ageing, shocking use cause erode, the accident circumstance that in safeguarding, appears. Require special attention the happening of the following phenomenon: -Covering layer occurrence break, nick, burst, disconnect etc can bring about internal composition to appear - if leak appears above circumstance, need to change tube. Below certain and specific use environment, need to make clear expire date uses security with ensuring. Date is tagged go up at tube, instant tube has not appear fail to also answer instantly disuse. 8.

Repair a general reason condition not to suggest to repair tube. If special situation wants to repair, need what strict comply with gives birth to severe business to repair an opinion. Repair after ending, need to undertake pressure checks. If tube causes pollution because of cut directly, and tube others still accords with food to produce a demand, can excise suffer pollution to be finished partly repair. Although installation note metal collapsible tube is compressible also but drawing, but if do not press proper place installation, can rupture very quickly, lower service life even. Metal collapsible tube is OK horizontal installation, OK also and perpendicular installation or inclined Xiang An are installed. Optimal condition is perpendicular installation, should avoid installation to be near the wheel at the same time, can add outfit fender when necessary. What does metal collapsible tube install a note to have? Can be cent of metal collapsible tube commonly 3 kinds of length: The 1st kind is to reduce length, the length; when compressing tube to ultimate position namely is installation length the 2nd kind, the length; of the tube when the intermediate position that this is the half that is in quantity of the biggest displacement is drawing length the 3rd kind, tube is gone to by drawing the length when the biggest limit. Intermediate position should be in tube when tube is installed, namely alleged installation length. Here the position installs condition to fall, tube can be had 2 mobile way when axial load, be like otherwise can move to a direction only, will affect the intensity of metal collapsible tube, lower service life. In installing a process actually, consider with rule by computation the result measures tube length to undertake installing may be affectinged manufacturing efficiency again, business of foreign some production assembles rule on tube directly, after installation is over, cut off rule. 1, when choosing metal collapsible tube, cover the metal collapsible tube of flange for the pine to facilitate installation chooses one end as far as possible please. 2, face of metal collapsible tube should be protected when construction site undertakes electric welding works, prevent solder broken bits and metal collapsible tube of the burn that bring arc. 3, twist of forbidden metal collapsible tube is installed. 4, should not bend along ministry of root of metal collapsible tube, not due dead turn. 5, what connect medium to must not be in charge of material to have to ripple caustic, in medium chloric ionic content should install graphic representation ≤25PPM6, strictly to install means installation correctly. (See installation guideline) 7, sealing surface of forbidden damage flange. CNC Milling
