MSS SP-58 Hanger Types

MSS SP-58 PIPE HANGER & SUPPORT TYPES REFERENCE · Basis: MSS SP-58 (2018) 'Pipe Hangers and Supports - Materials, Design and Manufacture' | Rev 1 | Created 2026-04-23

Fig. No. Hanger / Support Type Description Typical Service Max Temp (F) Std Load Rating Common Application
1 Adjustable Clevis Hanger Steel clevis & hanger rod, vertical adjustment General indoor/outdoor piping 750 A325 bolt capacity Most common hanger for 1/2 to 24 in pipe
3 Steel Pipe Clamp Two-bolt clamp around pipe OD Heavy vertical and horizontal 750 To 22,000 lb Large bore chilled/hot water & utility
4 Steel Yoke-Type Pipe Clamp Heavy duty yoke clamp for vertical risers Vertical riser clamps 750 To 10,000 lb Risers in power plants, refineries
5 Pipe Roller (single) Cast iron saddle on roller Horizontal axial movement 450 To 3,000 lb Steam, condensate lines w/ thermal movt
7 Pipe Roller Chair Four-bolt roller chair, thermal movement Horizontal allow axial + lateral 450 To 6,000 lb Long runs of steam line on pipe rack
8 Roller Hanger Roller mounted on clevis hanger rod Horizontal pipe w/ axial movement 650 To 3,000 lb Moderate temp steam/hot condensate
9 Adjustable Pipe Roll Stand Stand-mounted roller with jacking screw Floor/support mounted roll 650 To 10,000 lb Large-bore steam on sleepers
10 Pipe Roll Stand Roller on heavy stand Heavy horizontal pipe 450 To 50,000 lb Large lines on pipe racks, boiler feed
11 Single Pipe Roll Roller assembly with rollers only Horizontal support with movement 450 To 10,000 lb Ahead/after anchor points
13 Steel Turnbuckle Adjustable rod length Hanger rod adjustment 650 Per rod size Paired with Fig 1/8 hangers
24 U-Bolt Threaded U-bolt around pipe Horizontal & vertical pipe 450 Per U-bolt grade Small-bore instrument & utility
35 Single Pin Connection Pinned rod attachment Rod-end connection 650 Per pin Standard pipe hanger hardware
39 Welded Steel Bracket (light) Steel bracket welded to vessel/wall Light bracket / pipe shoe support 650 To 1,500 lb Single pipe to structural steel
40 Welded Steel Bracket (medium) Medium duty welded bracket Medium bracket support 650 To 3,000 lb Medium-bore pipe runs
41 Welded Steel Bracket (heavy) Heavy duty welded bracket Heavy pipe shoe support 650 To 6,000 lb Large-bore pipe on pipe rack
43 Side Beam Bracket Wall-mounted side beam bracket Side support 650 To 1,500 lb Attached to steel W-shape
59 Adjustable Band Hanger Light-duty band with adjuster Light piping, small bore 250 To 800 lb Plumbing, gas, HVAC
66 Pipe Saddle w/ U-Bolt Saddle over insulation with U-bolt Insulated cold line support -320 to 250 Per U-bolt Cryogenic LNG, LCO2, chilled water
68 Clamp-and-Lug Type Bolt-on clamp with lugs Vertical hold-down 650 To 5,000 lb Riser clamp with preventing slip
82 Horizontal Traveler (variable) Variable spring travel unit Horizontal thermal movement 1100 Per spring rate High-temp piping w/ thermal growth
98 Pipe Slide (graphite PTFE shoe) Pipe shoe on low-friction pad Allows axial translation, stops vertical 1000 Per shoe Steam/process lines on racks
A Constant Support Hanger Linkage maintains constant load Vertical travel w/ constant load 1100 Per CSH rating Critical lines w/ thermal growth (reboilers, turbines)
B Variable Spring Hanger Coil spring with 25% max load variation Moderate vertical travel 1100 Per spring General high-temp piping w/ thermal growth
APPLICATION NOTES
1. Figure numbers correspond to MSS SP-58 Table 1 (metallic) & Table 2 (non-metallic) hanger components. Load ratings are typical catalog values from Anvil/Grinnell/Bergen-Paterson; verify against mfr data.
2. Temperature ratings are for the HANGER MATERIAL, not the pipe. Carbon steel hangers limited to 750F; above 750F use chromoly (F22) hanger components and PTFE/graphite slide pads.
3. For thermal movement > 1/4 inch and pipe temp > 200F, use rollers (Fig 5/7/8/9) or spring hangers (Fig A/B, Type F82). See MSS SP-58 Table 3 for travel selection.
4. Constant Support Hangers (CSH) are used where dead weight shift would be > 25% (e.g., reboilers, steam turbine nozzles). Variable Spring Hangers (Type B) permit 25% load variation over travel range.
5. Insulation-shoe types (Fig 66) must be sized to clear insulation OD and provide moisture drip path.
6. Material selection per MSS SP-58 Sec 4: CS A36/A53 for < 750F, A105 forgings for higher temp, SS 304/316 for corrosive/cryogenic, galvanized for outdoor.
7. For seismic design (IBC Ch. 13), add longitudinal restraint per ASHRAE 171 / OSHPD / IBC Table 13.6-1. Seismic brackets NOT in SP-58; see MSS SP-90.
