Protection Tubes Form 2 G

Protection tubes form 2G as defined by standard DIN 43 722 are a straight design, are open at one end and equipped with a bottom at the other end. Alternatively this end can also be welded or dished. Contrary to form 2 a further screw joint is mounted to the protection tube to screw the protection tube into the process connection.

Protection tubes form 2G are available with diameters of 9 mm, 11 mm, 12 mm and 14 mm.

The screw joint mounted to the protection tube is available with the standard process connection threads G1/2" and G1". Other thread sizes are available on request, like e.g. NPT threads.

The total length of the protection tube is composed of the extension pipe length (above the screw joint on the protection tube) and the insertion length (measured from the sealing face of the screw joint). The standard insertion lengths are 160 mm, 250 mm and 400 mm. Other lengths are avaiable on request.

The ordering code of the protection tube is composed of the component name, design type, diameter, identification letter of the material number, extension pipe length, insertion length and process connection thread.
