PTFE Moulded and Machined Finished Products
It is often more efficient to use moulded semi - finished products to avoid excessive machining of relatively expensive materials and also to reduce machining labour and time.

The tooling costs are generally very low.

PTFE Soft Unsintered Products
IPTFE Universal Rope Gasket
PTFE Rope Gasket is a specially formulated sealing material that withstands vibration, wide operating temperature range and has extremely low coefficient of friction. The friction free characteristic promotes smoother action an increases the life of the gasket many times over.

It is used as a gasket on flanged connections, pressure vessels and all other similar mating faces as well as packing for valves and similar gland applications.
 

IPTFE Thread Sealant Tape
Unsintered pure PTFE in tape form is the standard material for sealing threaded joints and connections. Joints can be taken apart long afterward without any trouble. It is virtually a universal sealing material which can be used on pipes of galvanised Iorn, Rubber, Copper, Plastics, Brass, Aluminium, Stainless Steel, Ceramic, Monel, Carbon etc.

The inherent plasticity of PTFE allows it to extrude into the irregularities of the thread, so filling any voids or passages. It is insert to acids, solvents, oil etc. and will not contaminate the liquid being handled.

PTFE Gaskets - Envelope / Solid

These gaskets are successfully used in chemical plants, glass/glass lined equipment due to their high temperature, corrosion and ageing resistance. Envelop Gaskets are produced in two forms:-

Milled and Slit forms
Milled type envelop is perhaps the better of the two since it is made to fit the insert and presents a flat face to the flange.
The Slit type is perfectly adequate for many applications where cost is a major consideration. The envelop in this variety does not present a full face to the flange.
Solid Gaskets can be made to order in different types of shapes and sizes.

PTFE Rings - Piston / Rider / Segmented Piston Rod Packing
Since PTFE is a self lubricating material non-lubricated bearings, seals, piston rings, rider rings, piston rod packing, chevron rings, O rings etc., are in great demand amongst desing engineers.

The use of fillers with PTFE changes certain properties and permits the material to be tailored to a wide variety of mechanical applications. In general, use of additives increases stiffness, hardness, compressive strength and resistance to deformation under load.

We manufacture these rings for all types of non-lubricated compressors.

PTFE Bellows Line, Valve, Stirrer
Type:

• Line; for Flanges
• Valve; with Spindle
• Stirrer

Used mainly in chemical process pipelines and chemical manufacturing equipment.

The following basic types are available:
 

PTFE Diaphragms for valves and pumps

Diaphragms with Neoprene Rubber Pad:

The almost universal chemical resistance, the high temperature resistance, the anti-stick, low friction surface of the PTFE Linings ensure minimum maintenance requirements. Low cost and efficient design along with long service life makes PTFE the most ideal material for use in valve and pump diaphragms.

PTFE Components for valves / Pumps with inserts / without inserts
Mechanically highly stressed components such as pump impellers, agitator vanes, plug valve cores etc., are provided with a rigid insert increasing the strength of the component and reliably transmitting forces.

Components required by you can be manufactured by us.

PTFE Lined Equipment - Pipes / Fittings

Advantages:

• High Chemical Resistance
• High Temperature Resistance
• Non Contaminating
• Low Cost
• Maintenance Free
• Long Durability

Lining of Pipes / Fittings as per your specifications also undertaken.

PTFE Flex-O-Seal Universal Joint Gasket

Introduction:
Flex-O-Seal is a unique sealing material manufactured from special grade of expanded 100% pure PTFE by transforming the fibrous structure by means of a special process. Though very tough, it is spongy and suited to almost all flanges, covers and narrow cavities. Its special soft and flexible character enables it to be the most ideal seal under pressure without significant cold flow even on irregular, badly damaged or corroded flange surfaces. Once bolted this gasket rarely need to be retorqued.

Properties: FLEX-O-SEAL recommended temperature-240°C, to 310°C, PH Range 0-14 No deterioration due to stocking for long time. Resistant to high pressure, non-toxic.
Not recommended for use against elemental fluorine, alkali metals and strong oxidising agents.

Application:
FLEX-O-SEAL is safely used in petroleum refinering companies even in their offshore operations, corrosive chemical processing, food processing, paper mill, marine installation, for glass lined or fibre glass reinforced vessels and tank lid sealing, manhole covers, vent pipes, heat exchangers, pumps or compressors housing flanges, valves and many more industrial applications where conventional pre-cut gaskets are not readily available or unsuitable.

Installations:

• The sealing surface must be clean, free from grease and dry to enable the gasket to stick properly.
• The width of the joint gasket is to be determined by the nominal diameter or type of flange. Selection of a tentative size of joint gasket would be approx, 1/3rd flange contact width inside the bolt hole e.g., 7 mm gasket joint to suit a 20 mm flange width.
• Remove the protective foil from the adhesive joint gasket to allow for fitting. Stick the gasket approx 2 mm away from the bolt hole and press on lightly.
• Do not butt the ends overlap them in front of a bolt (see fig. 1)
• Tighten the lubricated bolts in opposite pairs. Since it is highly compressible only bolt pressure is required to seal. The lap joint deforms perfectly to give a reliable seal.
• For delicate components such as glass flanges the gasket ends can be joined by cutting a step in each end of gasket.
• FLEX-O-SEAL is easy to install, able to fill severe surface irregularities and reduces inventory of ready made gaskets, envelopes, etc. It has therefore taken its name as UNIVERSAL JOINT GASKET.
• On irregular or damaged flanged surfaces, it is possible to build up with short length of FLEX-O-SEAL.

All technical data and information is based on our experience to date. They represent the current state of our knowledge but assume no legal re-sponsibilities. The customers are asked to check these details since the performance of a seal can be judged only where all necessary operating data are available.

PTFE Bellows for Lined Pipes

Bellows are specially designed form virgin PTFE and is contour moulded. This manufacturing method guarantess an excellent structure of the material; Symptoms of ageing are practically excluded. Very long term durability and low maintenance costs are assured.

These Bellows are manufactured in different sizes form NB 25mm to NB 500mm. The allowable operating pressures are depending on services conditions. The Bellows can be used upto200oC.

Bellows serve for compensation of:

• Vibration
• Thermal Strain and Expansion
• Axial and Redial motion

These Bellows are meant for resisting highly corrosive chemicals plants and piping for aggressive medias.
These Bellows are installed in PTFE Lined Carbon Steel Piping and equipment without additional gaskets. For use with piping and equipment made of glass, enamels and ceramics we recommend PTFE Gaskets, offered as accessory.

The sealing surfaces are covered end plates and individually boxed for protection against mechanical damage. Limit bolts are preset to prevent over extension during operation.
