MetalKeen designs and manufactures industrial piping supports and pipe hangers for critical pipeline systems. Our product range includes spring hangers, rigid supports, guide supports, anchor brackets, pipe clamps, and saddles, fabricated from carbon steel, stainless steel 304/316L, and galvanized steel. Engineered for petrochemical, power generation, HVAC, and marine pipelines, every support is manufactured to your drawing with optional load testing and NDT inspection.
A piping support (also called a pipe hanger, pipe bracket, or pipeline support) is a structural component that carries the weight of a pipe and its contents, restrains movement, and absorbs dynamic loads such as thermal expansion, vibration, and seismic forces. Proper support selection prevents:
Pipe sagging and stress cracking from excessive span lengths
Equipment nozzle overload from unsupported pipe weight
Thermal expansion damage to valves, pumps, and vessels
Vibration fatigue in rotating equipment connections
MetalKeen produces the full spectrum of pipe supports from standard catalog items to engineered custom designs.
Table
Support Type | Function | Key Feature |
|---|---|---|
Rigid Support (Rest) | Carries vertical dead load; allows axial and lateral movement | Simple, low-cost; used where thermal movement is minimal |
Spring Hanger (Variable/Constant) | Supports load while permitting vertical movement | Spring rate calibrated to pipe weight and thermal expansion |
Guide Support | Permits axial movement; restricts lateral and transverse displacement | Prevents pipe bowing while accommodating thermal growth |
Anchor Support (Fixed Point) | Restrains all movement (axial, lateral, vertical, rotational) | Transfers loads to structural steel or concrete |
Shock Absorber / Snubber | Dampens dynamic loads from earthquakes, water hammer, or pump trips | Hydraulic or mechanical damping; protects critical equipment |
Pipe Clamp / U-Bolt | Grips pipe OD and transfers load to hanger rod or support structure | Lined or unlined; split or solid design |
Pipe Saddle / Shoe | Distributes pipe weight over a broad support surface | Welded or bolted; flat-bottom or curved-base |
Trunnion / Dummy Leg Support | Supports branch connections or elevated pipe runs | Reinforced weldment with load transfer to main structure |
Base Support / Floor Stand | Freestanding support for low-level or underground piping | Adjustable height; corrosion-resistant coating |

Q1: What is the difference between a rigid support and a spring hanger? A rigid support (pipe rest or clevis hanger) carries the pipe weight at a fixed elevation and is used where thermal movement is negligible. A spring hanger supports the pipe while allowing vertical movement caused by thermal expansion or contraction. Variable spring hangers are used for moderate movement; constant spring hangers are used where the supported load must remain nearly unchanged throughout the travel range.
Q2: When do I need a guide support versus an anchor support? A guide support permits axial movement along the pipe centerline while restricting lateral displacement—used to prevent pipe bowing without restraining thermal growth. An anchor support (fixed point) restrains all movement and is used to divide the pipeline into expansion zones, directing thermal forces into expansion joints or flexible pipe legs.
Q3: What material should I choose for my pipe supports? For general industrial applications, carbon steel (Q235B/A36) with hot-dip galvanizing is cost-effective. For corrosive or hygienic environments (chemical, marine, food, pharma), 304 or 316L stainless steel is required. For high-temperature petrochemical service, alloy steel or carbon steel with refractory lining is used.
Q4: Do you provide spring calibration and load testing? Yes. Every spring hanger is calibrated to its rated load on a hydraulic test frame. We provide a load-deflection chart and calibration certificate showing cold load, hot load, and travel range. Proof load testing to 1.5× working load is available on request.
Q5: Can you manufacture piping supports from my piping isometrics or stress analysis? Yes. We accept P&IDs, piping isometrics, pipe stress reports (Caesar II, AutoPIPE), or simple sketches. Our engineers review the support locations, loads, and movements to recommend the optimal support type and verify that the design meets code requirements.
Q6: What standards do your piping supports comply with? Our manufacturing complies with ASME B31.1 (Power Piping), ASME B31.3 (Process Piping), MSS SP-58 (Pipe Hangers and Supports), EN 13480 (Metallic Industrial Piping), and client-specific specifications. Third-party inspection by TPI (SGS, BV, DNV) can be arranged.
Q7: Do you supply corrosion protection and fireproofing for offshore supports? Yes. We offer hot-dip galvanizing (ASTM A123), epoxy coating systems (NORSOK M-501), rubber/PTFE lining for clamps, and cementitious or intumescent fireproofing for offshore and petrochemical applications.
