Hydraulic Clamp Manufacturers in India

Sachiya Steel International is a leading hydraulic clamp manufacturer in India, supplying DIN 3015 Heavy Series hydraulic tube clamps for high-pressure tubing, hydraulic power packs, offshore skids, mining equipment, heavy machinery, and industrial systems. Since 2005, we have supplied EPC contractors, OEMs, and MRO teams across 100+ countries from our TUV/ISO 9001:2015-certified facility in Vasai, Mumbai. Our hydraulic clamps are designed for pulsating hydraulic service up to 400 bar, with liner materials selected according to the working fluid.

What Are Hydraulic Clamps?

Hydraulic clamps are heavy-duty tube supports designed for high-pressure hydraulic lines operating from approximately 100 to 400 bar. Unlike ordinary pipe supports, hydraulic clamps must withstand pressure pulsation, vibration, thermal cycling, and fluid compatibility requirements. DIN 3015 Part 2 Heavy Series clamps use a two-piece body with anti-vibration liners, robust base plates, and high-strength cover-plate bolts to reduce fretting, movement, and fatigue.

Types of Hydraulic Clamps We Supply

Sachiya Steel supplies a wide range of hydraulic tube clamps for demanding industrial applications, including DIN 3015 Part 2 Heavy Series clamps, U clamps, pipe fitting clamps, plumbing clamps, pipe lock clamps, anti-vibration hydraulic clamps, marine and offshore hydraulic clamps, and custom hydraulic clamps. Stainless steel, carbon steel, Duplex 2205, and special alloy options are available with NBR, EPDM, FKM Viton, and PA6 liners.

Hydraulic Clamp Technical Specifications

Our hydraulic clamps are manufactured according to DIN 3015 Part 2 Heavy Series and Part 1 Light Series where lower pressure is suitable. Standard sizes range from 6 mm to 219 mm outside diameter, with custom sizes available on request. Heavy Series clamps can be rated up to 400 bar for smaller ODs, while pressure ratings reduce for larger tube diameters.

Available materials include SS 304, SS 316L, Carbon Steel, Duplex 2205, and Hastelloy C-276. Surface finishes include zinc plating, hot-dip galvanizing, and electropolishing for stainless steel. Liner options include NBR for mineral hydraulic oils, EPDM for water-glycol fluids, FKM Viton for phosphate ester and high-temperature applications, and PA6 for suitable dry services.

Bolt options include Grade 8.8 and 10.9 carbon steel, A2-70 stainless steel, A4-80 stainless steel, and special high-temperature fasteners. Documentation can include ISO 9001:2015, EN 10204 3.1 / 3.2 MTC, CE marking, PED documentation, NACE MR0175, and PMI reports depending on project requirements.

DIN 3015 Heavy Series Size and Pressure Range

The Heavy Series covers hydraulic tube ODs from 6 mm to 219 mm. Typical maximum pressure ratings include 400 bar for 6–18 mm groups, 320 bar for 22–28 mm, 250 bar for 35–42 mm, 200 bar for 54–60 mm, 160 bar for 76–88 mm, 100 bar for 108–168 mm, and 63 bar for 219 mm. Actual pressure capacity depends on tube wall thickness, safety factors, and the specific application.

Material Grades

SS 304 offers good corrosion resistance for indoor and dry hydraulic systems and is commonly used on factory HPU manifolds and machine-tool hydraulics. SS 316L provides improved chloride resistance and is suitable for marine, offshore, and splash-zone applications.

Duplex 2205 provides higher resistance to chloride pitting and is suitable for subsea and severe marine environments. Carbon steel offers a cost-effective solution for dry-service applications when suitable protective coatings are provided. Hastelloy C-276 is available for demanding chemical environments where exceptional corrosion resistance is required.

Hydraulic Clamp Liner and Fluid Compatibility

Correct liner selection is essential for hydraulic clamp performance. For mineral hydraulic oils, NBR is the standard liner choice. For water-glycol fluids, EPDM is generally recommended. FKM Viton is suitable for phosphate ester fluids such as Skydrol and Fyrquel and is also preferred for higher-temperature applications.

Incorrect elastomer selection can cause swelling, softening, cracking, or liner extrusion. NBR should not be used with phosphate ester fluids, while EPDM is unsuitable for mineral oil and hydrocarbon-based fluids. Always confirm final compatibility with the fluid manufacturer before commissioning.

Applications of Hydraulic Clamps

Hydraulic clamps are used across oil and gas, hydraulic systems, marine, mining, power generation, automotive, offshore wind, injection moulding, and material-handling industries. Typical applications include drilling rig control lines, excavator hydraulic lines, HPU manifolds, ship crane hydraulics, mining equipment, turbine control-oil systems, injection-moulding machinery, subsea equipment, and mobile hydraulic systems.

For marine and offshore applications, SS 316L and Duplex 2205 are commonly selected for improved corrosion resistance. Mining applications often use galvanized carbon steel, while demanding chemical or high-temperature services can require FKM-lined stainless steel or special alloy constructions.

How to Choose the Right Hydraulic Clamp

Selection should consider operating pressure, pulsation frequency, vibration level, fluid compatibility, corrosion environment, temperature, mounting method, and certification requirements. Above 100 bar, DIN 3015 Part 2 Heavy Series is generally preferred for high-pressure hydraulic service. For marine environments, SS 316L is a common choice, while Duplex 2205 is suitable for severe chloride and subsea conditions.

The liner must match the working fluid and temperature. NBR is commonly used for mineral oils, EPDM for water-glycol, and FKM Viton for phosphate ester and higher-temperature applications. Clamp spacing should also be selected according to the tubing, vibration, and cyclic loading conditions.

Installation Torque

Correct bolt torque is essential. Typical dry-thread torque values for Grade 8.8 bolts range from approximately 9–10 Nm for M6, 22–25 Nm for M8, 44–48 Nm for M10, 76–84 Nm for M12, 190–210 Nm for M16, and 370–410 Nm for M20. Actual torque should be confirmed against the applicable DIN 3015 clamp group, bolt grade, lubrication condition, and manufacturer instructions. Retorquing after commissioning can help prevent loosening on high-cycle hydraulic systems.

Common Hydraulic Clamp Failure Modes

Common failures include fretting corrosion, liner extrusion, cover-plate bolt loosening, chloride stress corrosion cracking, NBR failure in phosphate ester service, and EPDM failure in mineral oil service. Proper material selection, liner compatibility, correct torque, suitable corrosion resistance, and appropriate installation practices significantly reduce these risks.
