DOUBLE METAL JACKETED GASKETS

Metal jacketed gaskets are formed by a soft material soul (FM, PTFE, graphite, etc.) coated partially or totally by a ductile metal foil. The quality of materials for the metal jacketed gaskets must be chosen according to the working pressure and the fluid with which it is in contact. Thanks to their understandable structure and light are more fully shown that the metal in pressures and high temperatures.

The metal jacketed gaskets can be manufactured with one or more ribs arranged in different configurations. The metal jacketed gaskets are based on standards such as ASME 16.20 or according to specific customer specifications. The most commonly used for manufacturing metal-plastic joints are materials as metal material: copper, aluminium, AISI 304, 316L, 321, soft iron and as filler material: mineral fiber or graphite.

  • DIMENSIONS AND FORMS:

The metal jacketed gaskets are manufactured in the most diverse circular, oval, rectangular, square, rhomboid forms, etc. These boards have no size limit however depending on the width limitation of commercial materials, sometimes requiring the use of welding which is performed following welding procedures. The standard thickness is 3.2 mm. although depending on the use, this may be higher or lower.

  • O-RINGS

    O-RINGS The use of O-rings extends to many fields. The main function that characterizes this type of joint is its ability to maintain the seal, preventing the mixture of liquids and gases. They are characterized by their versatility and resistance to high pressures and temperatures. The type of elastomer used in its manufacture can vary. We can offer […]

  • CPI-PTFE ST

    CPI-PTFE ST stainless steel lined  gaskets consist of a perforated stainless steel insert uniformly enclosed by PTFE. The synergy between the highly corrosion resistant PTFE mantle and the perfectly centred rigid stainless steel insert give the gasket exceptional chemical and mechanical properties preventing cold-fl ow in a wide pressure-temperature range. In extreme applications they are […]

  • RTJ GASKETS – TG30-TG31

    RTJ joints are indicated in applications high pressures and temperatures. They are designed to be accommodated in specific slots and flanges contact surfaces of the gasket and the flange must be carefully machined and finished. They are particularly suitable for very high pressures, up to 1000 psi. The RTJ gasket material should be a little softer than the flange itself […]
