Explore our high-performance pipe rollers, thermal clamps, and custom suspension hardware engineered for harsh industrial, cryogenic, and HVAC applications.
In modern industrial piping design, managing thermal expansion, dynamic load shifts, and rotational mechanical stresses is critical for pipeline system longevity. As leading roller hangers manufacturers and suppliers, we engineer pipe support systems specifically optimized to handle longitudinal movement resulting from severe temperature fluctuations in power stations, chemical processing facilities, and LNG distribution hubs.
Standard static pipe clamps often induce severe wear, fatigue failure, or localized pipe wall deformation when subjected to continuous axial contraction and expansion. Roller hangers address these failure modes by replacing sliding surface friction with low-coefficient rolling contact. This reduces axial resistance from typical coefficients of friction ($\mu \approx 0.35 - 0.50$) down to rolling resistance levels ($\mu \le 0.05$), safeguarding both the pipe insulation and structural host beams.
Core Technical Advantage: Roller hangers mitigate structural fatigue by absorbing thermal displacement over extended axial distances. By distributing point-loads evenly across precision-cast steel rollers, equipment wear is reduced by up to 85% compared to conventional rigid shoes.
Our industrial roller hanger assemblies are engineered using carbon steel (ASTM A36/A107) and stainless steel grades (SUS304 / SUS316L) to ensure high yield strength under heavy structural loads. The roller components are center-bored and mounted on heavy-gauge carbon steel axle pins, protected with hot-dip galvanization or epoxy finishes for extreme corrosive environmental exposure.

Our pipe supports adhere rigorously to global engineering and quality specifications:
Ningbo Ampy Pipe Co., Ltd. is a professional manufacturer specializing in pipe support systems, including pipe shoes, cold pipe supports for refrigeration, and insulated pipe supports for industrial applications. Located in Ningbo, a major port city with strong manufacturing capabilities, the company benefits from efficient logistics and a well-developed industrial supply chain.
Founded in 2013, Ampy Pipe started as a small-scale supplier of basic pipe supports for local construction projects. With continuous investment in engineering expertise and production equipment, the company expanded its product range to include advanced insulated and cryogenic pipe support solutions. By 2018, Ampy had entered international markets, supplying customized support systems for clients in the oil & gas, HVAC, petrochemical, and refrigeration industries.
The company offers a wide range of products, such as pipe shoes, sliding and fixed supports, pre-insulated pipe supports, and high-performance materials including polyurethane and calcium silicate supports. All products are designed to reduce heat loss, prevent corrosion, and ensure long-term system stability under extreme temperatures and operating conditions.
Ningbo Ampy Pipe Co., Ltd. operates under strict quality control standards and provides OEM/ODM services to meet diverse project requirements. With a commitment to innovation, durability, and customer satisfaction, Ampy continues to deliver reliable and cost-effective pipe support solutions to clients worldwide.
Delivering high-value engineering, competitive manufacturing costs, and seamless international port logistics from Ningbo, China.
Pipe hangers and roller support assemblies must adapt to contrasting climate conditions and localized construction standards. Ningbo Ampy Pipe Co., Ltd. designs custom pipe supports tailored to specific regional project needs:
Liquefied Natural Gas (LNG) pipelines operating at temperatures as low as -162°C experience intense thermal contraction. Our cold insulation sliding supports incorporate High-Density Polyisocyanurate (PIR) and Calcium Silicate blocks to isolate cryogenic piping from structural frame steel, preventing cold bridges and ice formation.
Corrosive, high-humidity chemical environments require robust surface protection. We provide hot-dip galvanized (HDG) roller frames and stainless steel (SUS316) axles tested under ASTM B117 salt spray tests to ensure over 25+ years of maintenance-free service.
For large-scale chilled water and steam distribution lines in high-rise commercial structures, our pillow-type sliding supports and heavy-duty roller hangers reduce noise transmission and structural vibration while allowing natural thermal elongation.
1. Smart Sensor Integration: Inclusion of load cell sensors to monitor strain on critical pipe nodes in real time.
2. Eco-Friendly Galvanizing: Zero-emission trivalent chrome plating processes to meet European REACH compliance.
3. Modular Pre-Fabrication: Pre-assembled hanger units shipped directly to project sites, cutting field installation hours by up to 40%.
Answers to essential technical, engineering, and international sourcing questions regarding roller hangers and pipe supports.
A roller hanger is engineered to support piping while accommodating axial thermal movement (expansion and contraction). By replacing sliding friction with continuous rolling action, it reduces stress on adjacent anchors, valves, and structural support beams.
Carbon steel with hot-dip galvanization is cost-effective for general HVAC, steam lines, and indoor/moderate outdoor industrial applications. Stainless steel (SUS304/SUS316) is recommended for highly corrosive environments such as marine off-shore rigs, chemical plants, and food processing lines.
Yes. All of our pipe support products, including roller hangers, spring hangers, and pipe shoes, are designed, fabricated, and load-tested in compliance with MSS SP-58 and ASME B31 standards.
Absolutely. Ningbo Ampy Pipe specializes in OEM/ODM services. We can customize dimensions, rod diameters, roller materials, and insulation blocks according to your specific engineering schematics.
We utilize high-density polyurethane (PIR), calcium silicate, and cellular glass blocks encased in protective vapor barriers to deliver optimal thermal efficiency without crushing under load.
Every shipment undergoes strict quality control inspections including dimensional checks, coating thickness verification (magnetic test), load-bearing testing, and raw material chemical analysis (MTR provided).
Standard product orders are typically fulfilled within 15-25 days. Custom OEM orders requiring new tooling take approximately 25-35 days depending on batch size and specification complexity.
Ningbo Port provides direct shipping routes to major global destinations across North America, Europe, the Middle East, and Asia, ensuring faster vessel loading, reduced inland transportation costs, and flexible shipping arrangements.
