Gaskets - Import export

Due to the wide range of different designs, perfectly suitable PTFE seals are available for every application. The PTFE gaskets from billi are characterized by high dielectric strength, excellent electrical insulation properties and a low thermal conductivity. All items are manufactured with a high processing quality. Discover the various PTFE gaskets in our online catalogue and order the right products for your application directly from billi. Depending on the respective requirements, different PTFE seals are suitable for you: Our comprehensive range includes, for example, PTFE thread sealing tapes with a temperature resistance of -200°C up to +260°C. The PTFE tapes are both, odourless and insoluble. In addition, the PTFE thread sealing tapes have a particularly low coefficient of friction, which improves their performances. We also offer PTFE cord with a pressure resistance of up to 10 bar. Possible applications include valves as well as piston and centrifugal pumps.

In order to be able to meet the individual requirements of our customers, we offer various types of spiral wound gaskets: For example, you can choose between standard versions with a smooth surface and various special models. All articles are based on a stainless steel strip and high-quality filling materials such as graphite and PTFE, which underlines the excellent quality standard. The spiral wound gaskets of billi are characterized by a constant elasticity during hot-cold cycles. Classical applications in the chemical industry include all types of gas lines, directional valves and pumps. Furthermore, spiral wound gaskets are the optimal solutions for pressure vessel openings in steam systems as well as low and high pressure in nuclear power plants. For the best possible functionality of spiral wound gaskets, the careful considered choice of model is of central importance: the versions with centering ring, for example, assures an ideal fit between the bolts.

The range in the graphite seals segment is not limited to rings and tapes, but also includes sheets: The many advantages of billi graphite sheets include the low permeability of liquids and gases as well as high resistance to chemical substances. In addition, the plates made of natural graphite convince for their enormous stability and high resistance to temperature fluctuations. The graphite sheets can be ordered in different versions so that the perfect items are available for every application: For example, you can choose from models without steel reinforcement, with plain steel inserts and tanged stainless steel reinforcement. All graphite gaskets from our company are convenient for the targeted interaction between a high quality standard and improved health protection: you can order asbestos-free graphite sheets and many other types directly from us at a reasonable price.

The function of gaskets is to prevent the leakage of medium outside the equipment. Static seals are used in many applications such as plumbing and heating systems, sealing fasteners, containers and pipeline construction. They are washers, rings or frames which generally are adapted to the whole width of the sealing surface. They can be used for example in flange connections of pipelines, pumps, motors, valves, etc. The gaskets are made of various materials such as: Rubbers, fiber plates, synthetic plates, graphite, PTFE, etc.

Metzner has developed the mandrel cutting machines of the SR series for cutting off sealing rings from injection-moulded or extruded tubes with different diameters. These machines are characterised by their unique processing method and high cutting quality. First, pre-extended "rubber tubes" are clamped onto mandrels. Due to the special design of the mandrels, the mandrel can be set up and removed quickly and without special previous knowledge. The mandrels are then automatically clamped in the machine between rotating spindles and production is started. A knife carriage travels along the tubes and cuts the flat sealing rings to the desired length with either push-fit or circular knives, depending on the requirements. This cutting method is particularly impressive with its high cutting quality in combination with a high output.

The special feature of the Metzner CCM 4: the circular cutting machine handles both wet and dry cutting. Depending on the type of cut, the CCM 4 is equipped with a water-cooling lubrication system or micro-knife moistening and preparation for suction. The standard model comes with an integrated discharge conveyor (800 mm length); application range both in-line and off-line. For tubes with suitable material properties the CCM 4 Gasket offers the possibility to cut flat gaskets with the circular knife. Suitable for tubes with max. 30 or 50 mm diameter and a tube length of 1 mm to 1000 m.
