Machine Teflon Lining for Pipe and Fitting

Teflon PTFE lining high viscosity in the gel state (it does not truly melt) prevents it from being processed conventionally in extruders or injection molding. PTFE tubing is therefore dry molded or extruded in hydraulic extruders with (paste extrusion) or without (ram extrusion) lubricants. Paste extrusion of PTFE yields flexible tubing. However, it occurs in a batch process and thus long continuous lengths are limited to the batch size, unlike the melt-processible fluoropolymers FEP, PFA and ETFE.

PTFE is highly corrosion resistant and lined equipment is used to convey the most corrosive and toxic chemicals in manufacturing plants around the world. 

This PTFE lining Extruder is to extrude PTFE lining,It keeps stable ram speed and produces precise high quality PTFE liner products. with our original technology. The PTFE liner ram extruder series from Sunkoo is able to extrude tube which dia from 20- 150mm.

Advantages:

* Save time and money; * Advance designed; * High output; * Low energy consumption; * Long-life; * PC touch screen,extremely user-friendly operation; * The extrude PTFE tubes physical properties is stable and adjustable;

A PTFE liner, which is several millimetres thick, protects the stainless steel reactor efficiently against corrosion, even against such corrosive media as acids and alkali. PTFE is distinguished by its excellent resistance to almost all chemicals, which makes it possible to do without many expensive special alloys. This significantly reduces the acquisition costs. 

The risk of possible cross-contaminations is easier to control with PTFE liners. Metallic catalysers, such as Pt, Rh, Raney Nickel etc adhere to steel reactors and are very difficult to remove. In the following experiments the question keeps cropping up if the effects observed are really caused by the change of catalyser, contamination effects or catalyst poisoning. This problem is elegantly evaded by reserving a PTFE liner for each type of catalyser.

PTFE Ram Extrusion Line

A ram extruder is an extruder where, instead of extrusion screw, a ram or plunger is used . The ram extruder was the earliest extruder to be used in the plastics industry. This typical process is applied for producing profiles, sleeves, rod, block, tubing, lining sheet bars, etc. The ram extrusion process is very effective for specific materials like PTFE which are not extruded successfully using screw extruder.

In this process plastic material in powder form is gravity fed into a chamber. In the extrudating chamber the resin powder is heated on sintering temperature. Ultra high molecular weight polyethylene, becomes gelatinous as it melts so it can be extruded with this type of processes. A hydraulic ram pushes the resin materials like PTFE, UHMW, etc. from the chamber to the die. The die actually gives the shape of the desired plastic like a rod, tube or a profile shape with the requisite internal or outer diameter. When the material comes out of the die, it moves the length of the conveyor. The profiles can be manufactured endlessly and cut by the continuous extruding of each length.

Types of Machines:

There are two types of ram extrusions- the vertical ram extrusion and the horizontal ram extrusion. Whatever be the type of ram extrusion, the resin feed, compaction or performing, sintering and cooling are all the same. But the extrudates quality depends on various parameter like the design of the extruder, powder properties, extrusion rate, pressure and temperature.

PTFE Virgin Rod

PTFE Virgin Rod Features:Usage temperature range is very broad (Celsius from - 200 degrees to +260 degrees); Anti-majority chemical substance's corrosiveness, except some fluorides and alkalinity moltenmetal;Excellent mechanical properties, aging resistance;Excellent flame resistance(Conforms to ASTM-D635 and D470 test step),in the air to be regulated as a flame retardant material;Very low water absorption......

One key importantadvantage of PTFE Rod is its operating temperature range,it can easily outperform other engineering plastics by being able to perform continuously at-250°C, right up to an amazing 250°C. Another important advantage of PTFE Rod is its outstanding co-efficient of friction, PTFE is in the record books ashaving one of the lowest friction values known to man. PTFE also has excellentacid and chemical resistance. Another feature of PTFE is its ability to set byor due to compression.

PTFE has excellent electrical resistance. PTFE is alsowater repellent and is often used in the manufacture of modern high performing,water repellent and breathable clothing.

PTFE is excellentfor low friction bearings, bushes, rollers and pulleys. PTFE is also almostexclusively used in cryogenic components due to its ultra low operating temperatures.PTFE Rod is regularly used for seals. PTFE Rod has become a very important engineering plastic used within the aerospace industry and aeronautics.

PTFE isoften used within the food industry companies. Another useful application overthe years has been in the use of product or component handles due to its resistance to heat and heat transfer. When an application for electrical resistance becomes too high for other materials, PTFE Rod can fill a very important gap.

Because PTFE hassuch a low co-efficient of friction it offers a material that when used willreduce load and drag in bearings to improve efficiency and reduce frictional losses and PTFE will outlast other materials. Because PTFE Rod will set due to compression, PTFE seals will conform to mating components resulting inexcellent sealing capacity. PTFE is reasonably easy to machine which helps withreduced machining costs and increased capacity and efficiency. PTFE isresistant to most acids allowing this material to be used in aggressive environments to where such materials as Polypropylene are unsatisfactory.

PTFE Thread Sealant Tape

With this PTFE Thread Sealant Tape, there's no need to use sticky, messy pipe dope when you're making repairs. The PTFE tape is great for producing quick, clean, air-tight seals. It's suitable for water, air or gas lines and works on threaded metal or PVC pipe.
Quick, clean, air-tight seals；Works on threaded metal or PVC pipe；Ideal for water, air or gas lines.

Thread seal tape (also known as PTFE tape or plumber's tape) is a polytetrafluoroethylene (PTFE) film for use in sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. It is also known by the genericised trade-name Teflon tape; while Teflon is in fact identical to PTFE, Chemours (the trade-mark holders) consider this usage incorrect, especially as they no longer manufacture Teflon in tape form. Thread seal tape lubricates allowing for a deeper seating of the threads, and it helps prevent the threads from seizing when being unscrewed. The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten, and instead making it easier to tighten.

Types

Thread seal tape used in plumbing applications is most commonly white, but it is also available in various colors. It is often used to correspond to color coded pipelines (US, Canada, Australia and New Zealand: yellow for natural gas, green for oxygen, etc.).In the UK, tape is used from coloured reels, e.g. yellow reels for gas, green for potable water.

* White – used on NPT threads up to 3/8 inch
* Yellow – used on NPT threads 1/2 inch to 2 inch, often labeled "gas tape"
* Pink – used on NPT threads 1/2 inch to 2 inch, safe for propane and other hydrocarbon fuels
* Green – oil-free PTFE used on oxygen lines and some specific medical gasses
* Gray – contains nickel, anti-seizing, anti-galling and anti-corrosion, used for stainless pipes
* Copper – contains copper granules and is certified as a thread lubricant but not a sealer

Thickness: 0.05-0.3mm or more (according your requirement);
Width: 8mm, 10mm, 12mm, 19mm, 25mm or others, according to your requirement;
Length: 8m, 10m, 12m, 15m, 18m, 20m ,25m, 40, etc..according to your requirement.

PTFE is widely used in a variety of needs, such as: anti-acid and organic solvents, which itself has no toxic to people, but one of the raw materials used in the production process of ammonium perfluorooctanoate (PFOA) is considered likely to have a carcinogenic effect.

Large relative molecular of PTFE, the lower one as hundreds of thousands, while higher one can up to one million or more (degree of polymerization of 104 orders of magnitude, while the polyethylene only 103). Degree of crystallinity is generally 90 to 95%, a melting temperature of 327 ~ 342 ℃. Molecule CF2 unit in PTFE arrange by zigzag shape, because the fluorine atom radius larger than the hydrogen, so the adjacent CF2 units can not cross exactly trans orientation, but form a spiral twisted chain, fluorine atom covering almost the entire polymer chain surface. This molecular structure explains various properties of PTFE. At temperatures below than 19 ℃ to form 13/6 helix; phase transition at 19 ℃, slightly unravel the molecular to form 15/7 helix.

Though the perfluorocarbon carbon – carbon bond and carbon – fluorine bonds are broken need to absorb energy 346.94 and 484.88kJ/mol, but PTFE depolymerization energy generate 1mol tetrafluoroethylene only need 171.38kJ. So in the pyrolysis, PTFE mainly depolymerizate tetrafluoroethylene. PTFE at 260,370 and 420 ℃ the weight loss rate (%) were 1×10-4, 4×10-3 and 9×10-2 per hour.
