From a fluid sealing perspective, pulp and paper manufacturing can be characterized as severe service, involving the use of aggressive chemicals, caustic fluids and high temperatures and pressures. Gaskets and seals for pulp and paper applications must be capable of servicing these demanding conditions. This blog describes how CRG can assist pulp and paper manufacturers to successfully address their fluid sealing needs and challenges.
Pulp and paper mills, depending upon their end product and manufacturing process, can have unique needs. Some mills produce a variety of end products and work in batch mode. Others produce a more limited product mix and use continuous digesting and processing to produce their products. The fluid sealing needs of each type of mill can therefore be quite different.
Given this fact, CRG can work with individual mills to optimize the supply of fluid sealing products. We can work with mill purchasing and stores to ensure that the supply of product is both economical and reliable and, at the same time, assist plant engineering and maintenance with material and gasket selection and installation guidance and training. Our objective in all cases is to reduce the incidence of gasket failures and problems, streamline the supply process, and enhance process performance and safety.
Some examples of fluid sealing products that CRG can supply to pulp and paper mills include the following:
Gaskets and seals from Tealon® sheet. Tealon® sheet from Teadit is an excellent material choice for applications involving strong caustic fluids and aggressive chemicals. In hot compression tests, gaskets produced from Tealon® sheet outperformed those made from skived PTFE. In these tests, the skived PTFE gasket showed a very high leak rate, losing 60% of its initial pressure by the end of the test. In comparison, the Tealon® gasket lost only 6% of its initial pressure by the end of the test and showed a leak 10 times less than that of the skived PTFE gasket. This superior performance can translate into reduced costs and improved equipment uptime and availability. Tealon® sheet is available in a range of styles from which CRG can fashion gaskets and seals to suit specific applications and equipment.
Gaskets and seals from GR1700 sheet. Teadit GR1700 – SIGRAFLEX APX2 Hochdruck is a multilayer, high-strength gasket sealing sheet designed for high-temperature applications. Gaskets made from GR1700 sheet perform particularly well in critical applications due to their high mechanical strength and the blow-out resistance, working pressure resistance up to 3600 psi (250 bar), excellent chemical resistance, very low cold or hot relaxation, and the maximum permissible gasket stress.
Compression packing. CRG supplies Teadit compression packing to service pulp and paper applications. Styles that we often supply for pulp and paper applications include the following:
