Characteristics
Planisteel Camprofile gaskets are composed of a metallic core serrated on both sides, subsequently covered with a graphite tape that provides the sealing function. The concentric grooves of the core ensure excellent tightness even with reduced bolt loads, while the facing guarantees adaptation to surface irregularities of the flanges.
Unless otherwise specified by the customer, the profile design is manufactured in accordance with ASME B16.20. Planisteel Camprofile gaskets can also be manufactured in compliance with EN 1514-6 and EN 12560-6, or with other customized profiles.
According to the EN 1514-6 classification, Planisteel Camprofile gaskets can be manufactured without a ring (NR), with an integral ring (IR), or with a loose/non-integral ring (LR). The material of the loose location ring may be carbon steel.
The typical construction details of Planisteel Camprofile gaskets are as follows.

- The sealing factors refer to the IR and LR design of the stainless steel gasket.
- Graphite cannot be used with oxidizing fluids. With non-oxidizing fluids, the maximum temperature of 550 °C applies to RF flanges, while for LMF and LTG flanges the limit is 650 °C.
Applications
Gaskets for line flanges and heat exchangers suitable for pressure classes 150 to 2500. They are designed for sealing flanges in all applications in chemical plants, petrochemical plants, refineries, and power generation facilities.
