Cartridge mechanical seals manufactured to meet API 682 (ISO21049) are meant for use in the petroleum, natural gas and chemical industries. During processing of crude oil various chemical compounds are being released, and designers should count on sealing fluids which could be: -under the very high pressure -under very high or very low temperatures -on very high or low pH value -very high or very low viscosity -abrasive -harmful, polluting and potentially explosive API 682 (ISO21049) specifies requirements and gives recommendations for sealing systems with aim to secure that the fluids with characteristics above could be transported: -with minimum waste -with maximum environmental protection -with minimum mechanical failure -with best price-quality ratio

Rotary pressure joint is an assembly which secures sealing between inlet pipe and rotational cylinder thus providing heat transfer by media in or from the equipment's rotational element. Fluids that are commonly used for heat transfer are water, thermal oils, hydraulic oils, cooling fluids and vapor. When it comes to rotary pressure joints, sealing of work fluids is done by the use of mechanical seal. The mechanical seals spring provides contact between sealing faces before the machine starts it's work, while during work, the contact is secured by the act of hydraulic pressure, except in cases of low operating pressures or vacuum. The right choice of mechanical seal is of major importance in order to reach the work of rotary pressure joint efficient , because in cases of mechanical seal malfunction, leakage occurs which reduces efficiency of entire cooling or warming process. “ Kroma Ltd” delivers rotary pressure joints with either single or dual flow.

Body material is excellent corrosion resistant stainless steel (SUS304). Suited for use in tough conditions such as ocean development. Although it is made of stainless steel, the unique “inner seal mechanism” enables the working pressure of 20.6MPa {210kgf/cm2}, the same as steel’s. Safety lock ensures tight and secured connection (preventing accidental disconnection) under vibration or impacts. Both socket and plug have builtin automatic shutoff valves that prevent fluid outflow on disconnection. Easy to handle.

Single-acting mechanical seals are designed with two seal rings with one interface and without any seal liquid chamber. This type of mechanical seal has therefore to be operated either under dry conditions or must be lubricated and cooled by the liquid product.

Double-acting liquid-lubricated mechanical seals are the most common type for mixing applications. These seals can be used under nearly all operating conditions in a mixing vessel. They can also be designed as a gas-lubricated version in which a continuous supply of gas into the seal chamber maintains a marginal gap, thus preventing wear of the seal rings.

Triple acting mechanical seals feature two seal chambers. They are especially designed for demanding processes requiring a high degree of operational safety. They can be used for extreme pressure applications or for sealing extremely toxic or explosive products.
