PTFE Support Rings

diflineintroSend Enquiry

This adapter ring made of PTFE-lined steel is used for sustaining PTFE support grids, perforated plates, caps, etc. It is assembled by means of selfcentering external bolts.

Support rings are generally used to support structured packing such as high performance packing in pipe Sections. Up to DN 300 nominal size they are made of selected quality PTFE. In larger nominal sizes PTFE-sheathed steel rings are used. These also act as a support flange for the column section. Support rings are clamped between the buttress end faces using longer bolts in the coupling. The rings have a bead on both faces, so that no additional gasket is required.

FLAT/TAPER END PLATES FOR PTFE LINED COLUMNS

The use of end plates is recommended for sealing the top and the bottom sides of columns. The connections are dimensioned according to 3G experience and to the equipment available. The bottom plates can be the taper or flat types.

PTFE Thread Sealant Tape

diflineintroSend Enquiry

Thread seal tape is a polytetrafluoroethylene (PTFE) film cut to specified widths for use in sealing pipe threads.

Also known as plumber’s tape, PTFE tape, tape dope, it is popularly but incorrectly called Teflon tape. The low friction of PTFE allows the tape to be used as a lubricant in tapered pipe threads, which more easily allows them to be screwed together to the point of deformation, thus creating the seal.

Typically the tape is wrapped around a pipe’s thread three times before it is screwed into place. It is commonly used commercially in such applications as pressurized water systems, central heating systems, and air compression equipment.

TA4100 Expanded PTFE tape

It is an inorganic sealant tape for static applications made of 100% virgin PTFE. A unique process converts PTFE to a microporous fibrous structure, resulting in a sealant tape with an unsurpassed combination of mechanical and chemical properties.
TA4107 Expanded PTFE tape with self-adhesive

For easy fixing onto the sealing surface, there is normally a self-adhesive strip which is covered with a protective tape on one side of the TA4100.

Application:

EPTFE tape is especially suitable for sealing flange connections, pipe systems, hydraulic and pneumatic systems, etc. In addition, it’s also ideal for seals in glass, enamel and plastic flanges, vessels and special shaped sealing surface. EPTFE tape saves money and time. Since there is no scrap or waste, it costs less than other gasket materials. By using only a few sizes, large inventories of sheet gasket and costly precut gaskets can be eliminated. Installation time is kept to a minimum since there are no templates, precutting or special fitting requirements.

Expanded PTFE Gasket Sheets

diflineintroSend Enquiry

ePTFE- Gasket Sheet is a technologically advanced gasketing material providing all advantages of PTFE in a pure expanded form that resists cold flow, Flexible and economical, it is fast, easy to cut and install. These are supplied as pre-cut gaskets or in sheet form to cut on site as required.

Because of its multidirectional fibrous texture, ePTFE – Gasket Sheets show very good material characteristics at high surface pressures and increasing temperatures. Even under extreme operating conditions there are very low changes in width and in height, compared to other PTFE materials. By using gaskets made of ePTFE SHEETS high surface pressures will be maintained also at high temperatures.

ePTFE – Gasket Sheets is especially designed for highest safety requirements and for the application in critical joints such as flanges in oxygen pipelines.

For various applications the ePTFE – Gasket Sheets are available in diverse dimensions, heights and densities.

EPTFE (Expanded PTFE) is a Universal Expanded PTFE Sheeting sheet gasket material for most services. Seals rough and irregular surfaces. Made from biaxial oriented expanded PTFE sheeting that is laminated to the required thickness. Seals of up to 3000+psi can be achieved depending on the flange type & design and type of media being sealed. Chemically resistant over the Q-14 pH range. Specific gravity: 4 to 6. Suitable for temperatures to 315 °c.

CONSTRUCTION EPTFE

gasket sheet is manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The resulting product exhibits characteristics significantly different than conventional PTFE sheet. EPTFE is much softer and more flexible than regular PTFE sheet and thus conforms easily to irregular and rough surfaces. In addition, the material is easier to compress and minimizes creep and cold flow.

APPLICATION / SERVICE

EPTFE is an all purpose gasket sheet that can replace all other types of PTFE sheet. It will seal all aggressive chemicals over the entire 0-14 pH range except for molten alkali metals and elemental fluorine. Made from 100% virgin PTFE, EPTFE not only resists chemical attack, but it will not contaminate or discolor end products. These industries currently use expanded PTFE sheet:
• Distilleries                                          • Food and Beverage
