Pipe Couplings
Application
Straight-through sleeve joints of "SEZAMOR" type are designed for connecting pipe
sections in various systems on watercraft. They can also be applied in different
types of shore installations.
Construction
Straight-trough sleeve joints of SEZAMOR sp. z o.o. type consist of a jointing sleeve,
rubber sealing rings, flanges and joint drawbolt. The plug screwed in the centre
of the sleeve acts as limiter against slipping off joint from the pipe.
Thermal expansion gap (marked with symbol "X" on drawing) enables expansion joint
of pipe sections to be connected and allows to replace the sealing rings without
disassembly of pipeline. The joints are protected with anticorrosive zinc coating.
Technical Characteristic
Maximum working pressure for all sizes of joints is 1.6 MPa. Range of working temperatures
from 233 K (-40°C) to 403 K (+130°C). Media flowing through pipelines: fresh water,
seawater, hot tap water, fuels, oils and other non-aggressive liquids and gasses.
Pipelines with joints of SEZAMOR sp. z o.o. type should be protected against a possibility
of shifting pipes to be connected. Permissible deviation of axis of symmetry of
adjacent pipe sections to be connected with joints is 2° in relation to joint longitudinal
axis.
They are made in accordance with the requirements of the following Classification
Societies: PRS, LRS, GL, DNV, BV, ABS, Register of Russia.
Example of Designation
Straight-through sleeve joint DN 100 denotes a sleeve joint with a nominal diameter
DN 100.
