What is DIN 3015?
DIN 3015 is a widely referenced German standard for pipe support clamps. For procurement and engineering work, the key value is the ability to specify a defined clamp geometry and series instead of relying on a generic description such as ‘hydraulic pipe clamp’.
DIN 3015 Part 1 – Standard/Light Series
Part 1 covers the standard/light series. It is commonly used for general hydraulic, lubrication and instrumentation lines where the mechanical duty is within the series’ design range.
DIN 3015 Part 2 – Heavy Series
Part 2 covers the heavy series. The reinforced configuration is intended for demanding mechanical conditions, including larger lines and higher shock or load requirements.
DIN 3015 Part 3 – Twin Series
Part 3 covers twin arrangements that secure two parallel pipes in a single clamp body. This configuration can improve routing density where two lines need to stay together.
How engineers should specify a DIN 3015 clamp?
Do not stop at ‘DIN 3015’. Specify the relevant part/series, pipe OD, body material, hardware, mounting plate or rail, service conditions and quantity. This makes the requirement much more actionable for suppliers.
DIN compatibility and replacement projects
For replacement work, compare the installed clamp’s dimensions, series, bore, centre distance and mounting arrangement. A supplier may offer an equivalent, but fit should be confirmed from technical drawings or samples before a critical installation.
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 DIN 3015 pipe clamps?
Din 3015 pipe 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.
