What are hydraulic bore clamps?
The term ‘bore clamp’ can be used in search and procurement language for clamps associated with a defined bore or tube diameter. In practice, the critical selection parameter is normally the outside diameter of the line being supported, along with the clamp series and application duty.
Why OD matters more than the word ‘bore’?
Piping specifications often use nominal bore, inside diameter or DN language, while clamp bodies grip the outside of the pipe/tube. Procurement should therefore verify the actual OD before selecting the clamp size.
For high-pressure systems, look beyond pressure rating
High-pressure hydraulic circuits can experience pulsation, pressure shocks and vibration. Clamp selection should consider the complete mechanical environment: line size, support spacing, fittings, hose-to-tube transitions, mounting rigidity and machine dynamics.
Material and corrosion considerations
PP and PA bodies are useful in many industrial environments, while aluminium or stainless hardware may be preferred for specific fire, conductivity or corrosion requirements. Stainless 304/316 hardware can be relevant in marine, offshore, chemical and washdown environments.
Installation practices that improve reliability
Use the specified hardware, ensure the clamp is correctly seated, avoid damaging the tube surface and follow the manufacturer’s recommended tightening and spacing guidance. Do not treat a clamp as a substitute for a correctly engineered pipe-support system.
Specification Table
| Input | What to confirm? | Why it matters? |
| Pipe/tube OD | Actual outside diameter | Determines clamp size |
| Series/duty | Light, heavy, twin, stacked, etc. | Matches mechanical load |
| Body material | PP, PA/nylon, aluminium | Controls environmental/mechanical suitability |
| Hardware | Steel, SS304/SS316, etc. | Corrosion and installation requirements |
| Mounting | Weld plate, bolt-on, rail | Fit and installation method |
| Service | Pressure, temperature, vibration, chemicals | Defines application risk |
FAQs
What is hydraulic bore clamps?
Hydraulic bore clamps are components used to secure, support and route industrial pipes or tubes. The correct specification depends on line OD, clamp series, material, mounting and service conditions.
How do I choose the right pipe clamp size?
Measure the actual outside diameter of the pipe or tube and match it to the manufacturer’s dimensional range. Do not select from nominal bore alone.
Which clamp material is best?
There is no universal best material. PP is a common general-purpose choice, PA/nylon can suit higher temperature or impact requirements, and aluminium can suit applications requiring a metal, conductive or non-combustible body. Verify the manufacturer’s limits.
What is DIN 3015?
DIN 3015 is a widely referenced standard for pipe support clamps. The relevant part/series should be specified along with dimensions and materials.
What information should I send for a quotation?
Send pipe/tube OD, quantity, service pressure and temperature, body/hardware material, clamp series, mounting method, required standard and any existing clamp part number or drawing.
