Expansion Joints
2.10.8.1
Slip Tube Expansion Joints
ASTM F 1007, single or double slip tube as indicated, designed for [1034]
[2068] kPa (gage) [150] [300] psig saturated steam working pressure.
Expansion joints shall be of the type which permits the injection of semi
plastic type packing while the joint is in service under full line
pressure. Slip tube shall be of chromium plated, wrought steel
construction, guided by internal and external guides integral with joint
body. Fit slip tube ends with forged steel pipe flanges or bevel for
welding into pipe line where indicated. Deliver joints complete with
packing and ready for installation.
2.10.8.2
Flexible Ball Expansion Joints in Piping
Capable of 360 degrees rotation plus 15 degrees angular flex movement.
Ball joints shall have steel bodies and polished steel balls. Provide end
connections to suit class of piping here in before specified. Seals shall
be of pressure molded composition designed for the working pressure.
Provide joints for [1034] [2068] kPa (gage) [150] [300] psigsaturated steam
working pressure. Cold set the joints as necessary to compensate for
temperature at time of installation. Do not use ball joints on superheated
steam or on joints subject to frequent flexure. Install ball joints in
strict accordance with manufacturer's recommendations.
2.10.8.3
Bellows Expansion Joints
ASTM F 1120 flexible guided type with stainless steel expansion element,
internal sleeves and external covers. Joints shall be designed for a
working pressure of [_____] kPa (gage) psig and a temperature of [_____]
degrees C F.
2.10.9
Pipe Hangers and Supports
MSS SP-58 and MSS SP-69, Type [_____] or Type [_____] of the adjustable
type, except as specified or indicated otherwise. Suspended steam and
condensate piping shall have pipe hangers Type [_____] with insulation
protection saddles Type [_____]. Provide insulated piping, except steam
and condensate piping, with insulation protection shields Type 40. Provide
bronze or copper plated collars on uninsulated copper piping. Support rods
shall be steel. Rods, hangers and supports shall be zinc plated, except
for uninsulated copper piping which shall be copper plated; cast iron
rollers, bases and saddles may be painted with two coats of heat resisting
aluminum paint in lieu of zinc plating. Axles for cast iron rollers shall
be stainless steel. Size hanger rods with a 150 percent safety factor for
