What is Pikotek gasket?
The Pikotek VCS gasket is a high reliability gasket used for both insulating and general sealing purposes in Very Critical Services. The gasket has a proven track record of integrity in aggressive sealing situations. The seal elements are replaceable in the reusable gasket retainer.
What is a LineBacker gasket?
LineBacker® sealing gaskets use a rectangular sealing element, referred to as a “quad” ring, in combination with a unique groove design to effectively seal and isolate flanges of all types. With the unique quad ring design, elastic memory is provided for elastomers not normally associated with this characteristic.
What are flange isolation kits for?
Flange isolation kits are used to seal and electrically insulate flanges, thereby maintaining the integrity of piping systems. By preventing metal-to-metal contact, they mitigate corrosion caused by galvanic action or when used in conjunction with a cathodic protection system.
What is a G10 gasket?
Nitrile coated G10 isolating gaskets are coated with a nominal . The gasket requires more load to seal than a LineBacker or PGE gasket, but will perform well where pitted flanges, warped flanges or non-parallel flanges (such as non-metallic flanges with molded, concentric convex rings) exist.
What does RTJ flange mean?
Ring-Type Joint
The Ring Type Joint flanges are typically used in high pressure (Class 600 and higher rating) and/or high temperature services above 800°F (427°C). An RTJ flange may have a raised face with a ring groove machined into it. This raised face does not serve as any part of the sealing means.
When should you use gasket insulation?
Insulating gasket kits can be used in all such places where galvanic corrosion protection and electrical insulation is needed. Common Application areas are piping/pipeline systems with seawater environments, offshore installations, chemical installations, oil refinery pipelines, etc.
What is the difference between RTJ and RF?
Answer: RF means “Raised Face.” RTJ means “Ring Type Joint.” RF flanges seal with a flat gasket, formerly made of asbestos but now made of more environmentally friendly material, designed for installation between the raised faces of two mating flanges (both with raised faces).
What is LM flange?
The flange face is the contact surface and used to seat the sealing gasket. ASME B16. 47 define various types of flange facing and surface finishes (RMS). Common Facings include Raised Face (RF), Ring-type Joints (RTJ), Flat Face (FF) Large Male (LM), Large Female (LF), Large Tongue (LT), and Large Groove (LG).
What are insulating gaskets?
The most common problematic area for a Piping/Pipeline System design is flanges. Insulating gasket sets or Flange insulation kits play an important role in such cases. They are designed for electrically insulating the flanges. They act as an insulator between dissimilar metallic flanges.
What is insulating kit?
» Insulation kits are used to provide electrical isolation between the metal surfaces of a flanged joint, by means of eliminating any metal-to-metal contact between the flange face and fasteners.
What is insulation gasket kit?
Insulation Kits are High-Integrity Flange Gaskets & Seals for Increased Pressure & Critical Service Applications. Flange Insulation Gasket Kits are designed for preventing electrical conductivity between the flanges.
