Product Overview – Stainless Steel Pipe Clamps

Stainless steel pipe clamps are structural and positional fastening components that secure pipes, tubes, hoses, and conduits to supporting structures. Manufactured by press forming, roll forming, deep drawing, and precision punching of SS 304 and SS 316 sheet and strip, pipe clamps provide vibration-resistant, corrosion-proof pipe securing in environments where regular maintenance access is limited or impossible.

U-Bolt Pipe Clamps & Square Bend U-Bolts

SS U-bolt clamps, J-bolt clamps, square-bend U-bolts, and round-bend U-bolts are press-formed and threaded in SS 304/316 for pipe sizes DN15 (1/2″) to DN300 (12″). Supplied with hex nuts, flat washers, and backing plates as complete clamp assemblies. Used in marine, offshore, petrochemical, and structural pipe installations. Cold-forged threads for consistent engagement and clamp torque retention.

DIN 3016 / DIN 3567 Heavy Pipe Clamps

DIN 3016 heavy-duty pipe clamps, DIN 3567 heavy-duty pipe clips, and metric-series SS pipe holders with rubber liner inserts (NBR, EPDM, silicone) are press-formed and assembled to DIN dimensional standards. Used in German-standard process plants, automotive, marine, and industrial machinery. Available in M6, M8, and M10 bolt sizes with metric thread. EPDM or NBR rubber linings reduce vibration transmission and prevent bimetallic corrosion between SS clamp and dissimilar pipe material.

Worm-Drive Hose Clamps & Band Clamps

All-SS 304 and SS 316 worm-drive hose clamps, heavy-band clamps, T-bolt clamps, and perforation band clamps are roll-formed from SS strip with solid SS housings and SS screws. Bandwidth from 9 mm to 25 mm; diameter range 8 mm to 440 mm. Used for hose connections, flexible pipe joints, exhaust joints, silicone hose assemblies, and rubber boot clamps in automotive, marine, and process applications. Compliant with ISO 3722 and SAE J1670.

Loop Clamps & Single-Bolt Cushion Clamps

Single-bolt SS loop clamps with PVC, EPDM, or rubber cushion lining are used for small-bore tubing, hydraulic lines, instrumentation tubing, and electrical conduit securing in aerospace, shipboard, and process control applications. Sizes range from 6 mm to 50 mm OD. Loop clamp bodies are precision-stamped from SS 304/316 strip and comply with BS, DIN, and NAS standards for aircraft and marine use.

Two-Bolt Split Ring Pipe Clamps

Two-bolt heavy-duty split-ring clamps, half-saddle clamps, and full-ring pipe clamps are press-formed in SS 304/316 for pipe sizes DN25 to DN200. Used in process plant pipe repair, pipe anchoring, and lateral load support where single-bolt U-bolts are insufficient. Supplied with zinc-plated MS or full-SS fasteners as specified. Inner rubber lining options available for vibration absorption and surface protection.

Insulated Pipe Clamps & Cryogenic Clamps

Thermally insulated pipe clamps with phenolic, polyurethane foam, or Rohacell insulation inserts are manufactured for chilled water, refrigeration, LNG, and cryogenic service. Cold bridge prevention is critical in these applications — the SS outer shell is separated from the cold pipe surface by a high-density insulation liner. Used in LNG plants, cold storage facilities, and air-conditioning systems.

Corrosion Resistance & Material Selection

SS 304 pipe clamps resist atmospheric corrosion, freshwater, and mild chemical exposure. SS 316 clamps with molybdenum addition resist chloride pitting, seawater, and acid concentrations making them standard for offshore platforms, coastal installations, desalination plants, and chemical process areas. All-SS assemblies avoid galvanic corrosion that occurs when SS bodies are fitted with zinc-plated or HDG fasteners.

Vibration Damping & Noise Reduction

Rubber and EPDM-lined SS clamps significantly attenuate vibration transmission between pipe and structure, reducing fatigue failures in small-bore instrumentation tubing and hydraulic lines. Important in compressor rooms, pump stations, and reciprocating machinery areas where vibration-induced fatigue is a leading cause of pipe failure. Compliant with shipbuilding and naval standards for vibration isolation.

DIN & Metric Dimensional Compliance

DIN 3016-1 single-bolt clamps and DIN 3567-A heavy-duty clamps are manufactured to exact metric dimensions allowing drop-in replacement of OEM-specified clamps in European-standard machinery and process plants. Full dimensional certificates available. Popular for machinery export projects requiring CE marking and DIN-standard component documentation.

High-Pressure & High-Temperature Clamps

Heavy-duty two-bolt and four-bolt SS split-ring clamps are engineered for high-pressure steam, hot oil, and supercritical fluid piping where thermal cycling and pressure surges impose high clamp body loads. SS 316 is preferred for service above 400°C due to its superior high-temperature oxidation resistance versus SS 304.

Compact Loop Clamps for Instrumentation & Hydraulics

SS loop clamps in 6 mm to 50 mm OD range are essential for instrument tubing bundles, hydraulic manifold lines, pneumatic tube bundles, and multi-tube clamp blocks in offshore and process control systems. Modular stacking systems allow multiple tubes to be secured with a common back plate and single M8 fixing bolt, reducing installation time and structural penetrations.

Manufacturing Process

SS strip or sheet is cut to width and fed through roll-forming or progressive die press tools to create U-bolt blanks, clamp shells, and band profiles. Threading of U-bolt legs is performed on CNC thread rolling machines for consistent thread quality. Worm-drive housings are cold-headed and assembled with SS screws. Liner materials are die-cut and assembled into clamp bodies. Assembled clamps undergo torque and clamp-force testing before passivation, final inspection, and packing. Batch traceability is maintained through heat number records from raw material to finished assembly.
