[2.14.1
Guided Slip Tube
**************************************************************************
NOTE: Expansion joints shall provide for either
single or double slip of the connected pipes, as
required or indicated, and for not less than the
traverse indicated. The joints shall be designed
for hot water working pressure in accordance with
applicable requirements of EJMA-01 and ASME B31.1.
This joint is designed for packing injection under
full line pressure.
**************************************************************************
Internally-externally guided type, injected semiplastic type packing, with
service outlets. Joints shall be for minimum working pressure of ASME
Class 150. Provide single or double slip tube type as indicated. Provide
flanged or buttwelding end connections as indicated.
][2.14.2
Flexible Ball
**************************************************************************
NOTE: The ball joint will be designed for packing
injection under full line pressure to contain
leakage. Balls and sockets will be of equivalent
material as the adjoining pipeline. The exterior
spherical surface of carbon steel balls will be
plated with 0.051 mm (2 mils) of hard chrome in
accordance with ASTM B 650. The ball type joints
will be designed and constructed in accordance with
ASME B31.1 and Section VIII, Boiler and Pressure
Vessel Code, where applicable. Flanges where
required will conform to ASME B16.5. Gaskets and
compression seals will be compatible with the
service intended.
**************************************************************************
Provide chromium plated steel balls capable of 360-degree rotation plus
15-degree angular flex movement. Provide pressure molded composition
gaskets designed for continuous operation temperature of 274 degrees C 525
degrees F. Joints shall be for minimum working pressure of ASME Class 150.
Provide flanged or buttwelding end connections as indicated.
][2.14.3
Bellows-Type
**************************************************************************
NOTE: Bellows type joints must be flexible, guided
expansion joints. The expansion element will be
stabilized corrosion resistant steel. Bellows type
expansion joints will conform to the applicable
requirements of EJMA-01 and ASME B31.1 with internal
liners. The joints will be designed for the working
temperature and pressure suitable for the
application but will not be less than 1034 kPa (150
psig).
