Full Description
The seals available are of type IX for standard process piping applications and special HX type for subsea applications and other demanding applications such as extreme temperature. The seal type for compact flanges are self-energised and pressure assisted; the performance of such seal rings is dependent on using materials of high quality and strength. The deformation controlled functionality demands that strict dimensional tolerances are met, something our machine shop has 25 years of experience in achieving.
Our seal rings are available with coatings selected to suit the functionality of sealing for compact flanges. For subsea use, we will recommend our silver coated seals which is a very robust solution giving an extremely good and everlasting sealing performance. For topside applications, we recommend using MoS2 based dry film coatings. The seal rings used in TPC CFs are designed to be high reliability metal to metal seals and the use of PTFE type coatings is not recommended.
