1 1 ring - Joints RTJ1 EDGaskets Packings Expansion Joints Rubber and Plastic PartsRing- Joints RTJRing- joint gaskets are manufactured from a metallic mate-rial. The demands on the geometrical accuracy and thesurface quality are therefore high. This concerns both thegasket and the sealing section of the necessary surface quality depends substantial on theBrinell hardness of the gasket material. We have found thatthe relationRZ[mm] < 300/HBgives a useful distinction is made between two kinds of ring - joint gas-kets and two different calculation methods can be derivedthereof:1.

2 RTJ gaskets with a snuggle fitting radius (figure 1)a) The convex octagonal RTJ gaskets, profile AR 13, inwhich the cambered cone case surfaces of the gasketare pressed against the bevel cone case surfaces of thegroove during ) The oval ring - joint gasket, our profile A11, in which theball sealing surfaces are pressed against the cone this types the projection of the sealing surface width bDresults from the angle a, which the sealing surface againstthe force direction (pipe axis) forms as a function of the E-modulus ED and the number of contacting surfaces nbD = b1 + b2 = 100 r n sin.

3 Important: The surface pressure increase or decreasessub proportional to a possible change of thebolt RTJ gaskets with flat sealing surfaces (figure 2)The octagonal RTJ gasket, our profiles A13 and A14, inwhich the sealing surfaces are two cone case surfaces. Theprojection in the direction of the bolting forcebD = b1 + b2is to be set as the sealing surface : The surface pressure increase or decreasesproportional to a possible change of the calculations according to the preliminary standard DIN2505 with the gasket parameters k0 and k1, which representa fictive width, do not deal with the complicated conditionsin snuggle fitting application limits of oval and octagonal ring - joint gas-kets can be calculated more accurately as a function of thematerial, diameter, pressure and temperature among otherthings in accordance with the publication entitled"Optimisation of static gaskets", 3.

Here thegasket parameters are replaced by the values v and aswell as by the previous stated sealing width gaskets according to API and ASME standardsare mainly used in the petrochemical industry and inrefineries as a reliable gasket for pipelines with are entitled to give our products the API stamp of quality- thus guaranteeing compliance of the design with the latestAPI AR 13 with cambered flanks. The advantages whenusing convex shaped RTJ gaskets are explained in detailin the article entitled "The Latest on ring - joint Gaskets"which you can request from us as a special gaskets can also be manufactured as a blindprofile A11S, A13S, etc.

In the case of small rim widths theprotective gaskets are symmetrical, with larger rim widthsthey are unilaterally compensating caps, our profiles AK11, AK12,AK13, AK14, are supplied for damaged comprehensive calculations with regard to sealingflanged connections our gasket calculation service is atyour disposal at a favourable 1A13A14figure 22 ring - Joints RTJM aterials, profiles, surface pressure limits.
