1 TECHNICAL DESCRIPTION

1.1 PRODUCT NAME AND FEATURES

The subject of this O&MM is:

Cast iron threaded pipe clamp type 3150, with soft lining (elastomer) of the internal clamping surface

for the line pipe of the water system.

Cast iron threaded pipe clamp type 3160, with soft lining (elastomer) of the internal clamping surface

for the line pipe of the water system.

Cast iron flanged pipe clamp type 3151, with soft lining (elastomer) of the internal clamping surface for

the line pipe of the water system.

1.2 PURPOSE

The cast iron threaded pipe clamps type 3150 and 3160 as well as cast iron flanged pipe clamps type

3151 are intended for water supply systems, especially for potable water, industrial systems and gas systems

made of polyethylene (PE) and polyvinyl chloride (PVC). They may be used both in underground and

surface installations, in vertical or horizontal pipelines.

2 DESIGN

2.1 FITTING DESIGN DESCRIPTION

The factory "JAFAR" S.A supplies cast iron clamps with threaded and flange connections. The body of the

clamp is a semi-annular cast iron casting with an element allowing for connection of a discharge pipe with a

threaded or flanged connection. The second semi-annular element is the bottom section of the clamp. Both parts

are connected with bolts that allow for clamping it on the pipe to seal it. Between the body of the clamp and the

line pipe there is rubber lining which acts as the mount.

After clamping the unit with bolts connecting both halves of the clamp it is possible to drill an opening in the

pipeline and make an offtake connection.
