ISO Flange Assembly Instructions
ISO flanges are larger than KF flanges, similar to the KF flanges, they use a centering ring for sealing ISO flanges are widely used in systems that need frequent cleaning or disassembly.
There are two different methods to join the flanges together:1. Bolts (ISO-F, see diagram C) or 2. Claw clamps (ISO-K, see diagram A). These two flanges look very different, yet they can be joined together by using a single claw clamp(see diagram B).
A.ISO-K Flange with Double Claw Clamp B.ISO-K Flange with Single Claw Clamp
A.ISO-K Flange w B.ISO-K Flange and Nonrotatable with Rotatable Bolt Ring
Applications
ISO flanges are a sexless design made from 304 stainless, they can be used in a wide range of applications including
- ISO-KF fittings can be used in a wide variety of applications including:
- Roughing and foreline plumbing
- Small systems
- Systems requiring frequent cleaning or modification
- Research and teaching laboratories
- ISO-KF components are primarily designed for use at subatmospheric pressure. Because of the large number of elastomer seals used.
Description
The ISO-KF system is a modular, building block method ofcreating a piping system. There are several advantages in the use of ISO components. Since component dimensions are standardized, elbows,tees, crosses or valves for a given size may be interchanged. The flanges are ''sexless'' and the seal is symmetrical, so that the components are rotatable. By using ISO components, system assembly is quick and cost effective. See Figure 1 for the ISO dimensions of flange sizes 10, 16, 25, 40 and 50. These dimensions apply to ISO-KF flanges of these nominal diameters throughout this catalog.
