  1. Introduction to Fep spring tube

  The name of the spring expansion tube: Teflon coiled tube, Fep coiled tube, Fep coiled tube, Fep spring tube.

  Teflon telescopic tube is also known as Teflon spring tube. I don't know that spring tube is so called. When it comes to spring tubes, everyone may be more conceptual. Teflon spring tube, as the name suggests, looks like a spring, but the material is different. There are spring tubes made of PTFE, FEP, PFA and other materials. Teflon spring tube is a spring tube made of Teflon material. It is often used in heat exchangers and steam tubes; various frequency wire and cable sheaths, groove insulation tubes; various corrosive media (harsh solvents) transportation Pipes; liquid crystal manufacturing equipment; high-purity reagent delivery pipes; insulated pipes for oil-replacement motors; pipes for single-end light-emitting single-core optical fibers, pipes for air-conditioning wiring harness components and other fields.

  Common colors: transparent, black.

  2. Fep spring tube performance

  1. High and low temperature resistance: -196--260℃ high temperature, twice the strength of F4.

  2. It is non-sticky, fights water and oil, no fouling or flow inside and outside the pipe wall.

  3. Electrical reliability, high insulation, 601HZ-60MH high and low dielectric constant viscosity is 2.1. Even if the surface is damaged by diving, it will not conduct electricity; track volume resistance> 10180M surface resistance> 2*10130M; arc resistance> 165 seconds without leakage.

  4. Corrosion resistance: only elemental fluorine at high temperature, alkali metals play a role with it, and have no effect on all other concentrated and dilute inorganic organic acids, alkalis, and esters;

  5. Low water absorption: low absorption rate <0.01%;

  6. Non-combustibility: Will not burn in the air (oxygen index>95V0L%), non-toxic and physiologically inert;

  7. High transparency: the lowest light refractive index among all plastics; weather resistance: long-term exposure to ozone and sunlight;

  8. Ease of secondary processing: self-sealing, self-welding, flanging, and coiled pipes can be made.

  3. Common specifications of Fep spring tube:

  Inner diameter * outer diameter (unit: mm)

  Metric system: 2*4 3*5 4*6 5*7 6*8 8*10 8*12 9*12 10*12 12*14 14*16 16*18 18*20

  British system: 1/8 inch(1.6*3.2) 1/4(3.96*6.35) 3/8(6.35*9.525)1/2 inch(9.5*12.7) 3/4(15.88*19.05) 1(22.2*25.4)

  The specifications can be produced, with an inner diameter of 0.5mm to 200mm and a wall thickness of 0.12mm to 3mm.

  For specific customized specifications, please ask Fep manufacturer Teflon tube lady's house and so on.

  Four, Fep spring tube application features:

  1. High temperature wire and cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers;

  2. Suitable for making corrosion-resistant parts, wear-reducing and wear-resistant parts, seals, insulating parts and medical equipment parts;

  3. Poor fluidity, easy to decompose, and produce corrosive gas during decomposition. The molding temperature should be strictly controlled not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the pouring system should have low resistance to material flow;

  4. Translucent pellets, injection molding and extrusion molding. The molding temperature is 350-400 degrees, and the temperature above 475 degrees is likely to cause discoloration or air bubbles. And pay attention to demoulding will be more difficult.

  5. Uses of FEP spring tube:

  1. Liquid crystal manufacturing device;

  2. The whole body single-end light-emitting single-core optical fiber tube;

  3. Heat exchanger and steam piping;

  4. High purity reagent delivery tube;

  5. Various corrosive media (harsh solvents) pipelines;

  6. Various frequency wire and cable sheath, slot insulation tube;

  7. Slot insulating pipe for submersible motor;

  8. Pipes for air-conditioning wiring harness components;

  9. All-inclusive fluorine plastic type 0 sealing ring tube.

  My sister’s home with Teflon tube, Shenzhen DanKai Technology Co.,ltd., whose predecessor was Dongguan Dandi Insulation Material Co., Ltd. Fluoroplastic Material Factory, which was established in 1998, specializes in FEP, R&D, production and sales of PFA, PTFE and other fluoroplastic tube, rod, sheet and film products and other insulating materials. The company has a senior R&D team with international standards and a production line of fluorine plastic products imported from abroad. Some fluoroplastic products have passed ISO9001, SGS, FDA certification, and have been fully affirmed by domestic and foreign cooperative customers such as Huawei, Foxconn, Midea, ZTE, Intel, and AirTAC. The main products of the company are: ①Tubes: Ptfe tube, Fep tube, Pfa tube, Pvdf tube; ②Heat shrinkable tube: Ptfe heat shrinkable tube, Fep heat shrinkable tube, Pfa heat shrinkable tube, Pvdf heat shrinkable tube; ③Plate rod Membrane: Ptfe board and rod film, Fep board and rod film, Pfa board and rod film, Pvdf board and rod film; ④Insulation materials: silica gel, PE, PVC, UPE, etc.; ⑤Special category: PFA imported connector, spiral tube, spring tube , Rotary cut tube, welding rod, tee, straight-through, gasket, joint, taper rod, flared tube, sealing tube, braided tube, bellows, etc. At the same time, fluorine plastic products of various specifications can be customized and processed according to customer requirements.
