Flanged metal bellows expansion joints connect to pipes or equipment through flanges and are mainly used to accommodate thermal movement caused by temperature changes. Compared with weld-end bellows, flanged connections are easier to install, remove, and maintain, and can be customized according to piping pressure ratings, flange standards, bolt patterns, and equipment interfaces.

Yueding is equipped with product design, CNC machining, and stamping capabilities. Round, square, and custom-shaped flange connections can be produced according to DIN, ASME, JIS, EN, and GB standards or customer drawings. OEM and ODM production is available, and suitable product solutions can be confirmed based on nominal diameter, design pressure, operating temperature, media, required movement, and installation dimensions.

Copper Alloy Precision Bellows offer superior elasticity, sealing, and compensation for precision instruments, sensors, valves, and measuring equipment. Engineered with high-performance copper alloys, these bellows ensure optimal stability, durability, and cost-efficiency for demanding applications.

- Material options: Beryllium copper (high elastic stability), phosphor bronze (excellent elasticity & brazing), brass (cost-effective)
- Custom production support: Size, wall thickness, corrugation form, stroke, end connection, and assembly method
- Flexible services: Pre-quotation material review, sample-based orders, and small-batch production
- Applications: Precision assemblies, industrial sensors, valve compensation, and measurement systems

Pin-type quick release HD clamps are aluminum connection assemblies designed for turbocharger, intercooler, intake, and charge piping systems. Unlike screw-locking versions, the clamp housing is secured with a removable locking pin, so you do not need to repeatedly tighten screws during each disassembly and reassembly. This makes routine inspection, adjustment, and maintenance more convenient.

Complete Assembly: Clamp housing, weld ferrules, center sleeve, and sealing rings
MOQ: 10 sets
Mixed Sizes: Supported within one order
Custom Housing Color: Available
Custom Logo: Flat engraving or laser engraving
Packaging: Neutral box, individual packaging, or foam bag + box

Wire Spring Hose Clamps are designed for secure, fast fastening of low-pressure oil hose, air hose, water hose, and appliance hose connections. Available in single-wire and double-wire designs, with zinc-plated carbon steel or SS304 options, they support stable batch assembly, quick installation, and custom sizes for different hose and fitting requirements.

CV boot clamps keep automotive boots securely seated around CV joints, axle shafts and drive shaft connections.Available structures include pull-type clamps, guided single-ear clamps, multi-tooth adjustable clamps, multi-hole adjustable clamps, stepless ear type CV boot clamps and low-profile earless CV boot clamps. Tightening methods range from band pulling and position adjustment to ear crimping and stepless compression.Different designs can support CV boot clamp replacement, universal repair kits and repeatable production-line assembly.

Yueding supplies SUS201 and SUS304 CV boot clamps in bulk. Standard band widths include 6.5, 7, 8, 9 and 10 mm, with thicknesses of approximately 0.25–1.0 mm. Selected adjustable CV boot clamps cover diameters of approximately 6.5–120 mm, while pull-type CV boot bands can accommodate wider ranges through customized band lengths.Custom lengths, mixed-size combinations and matching CV boot clamp tools are available according to project requirements.

American type hose clamps are perforated worm-drive clamps used for hose and pipe fastening in automotive, agricultural machinery, industrial equipment, and general piping applications. The perforated band allows a flexible adjustment range, while the worm-drive structure supports regular tightening for repair, assembly, and general fastening work.

Yueding supplies American type hose clamps with regular reference sizes based on SAE size numbers and clamping ranges. 8.0 mm and 12.7 mm band width options are available, with common clamping ranges from 10–16 mm up to 228–254 mm, depending on the selected specification. For bulk orders, mixed sizes, or customer packaging requirements, we can help confirm the reference number, clamping range, band width, material grade, screw type, surface finish, and packing details before production.

British type hose clamps are non-perforated worm-drive clamps used for hose and pipe connection in automotive, machinery, and general industrial applications. The smooth band helps reduce surface damage during tightening, while the reinforced housing provides more stable clamping performance in applications where vibration may occur.

Yueding supplies British type hose clamps according to BS5315 reference sizes, with regular clamping ranges from 9–13 mm up to 260–280 mm. Welded housing, riveted housing, and tube / one-piece housing options are available. If you need bulk orders with mixed specifications or customized packaging, we can help confirm the band width, screw type, housing structure, material grade, surface finish, and packing details before production.

Application Scenarios:
Suitable for automotive exhaust, turbocharger and intercooler connections, industrial exhaust, and HVAC duct systems requiring quick assembly/disassembly with high vibration resistance; common procurement search terms include v-band clamp, v-band coupling, and double-bolt v-band clamp.

Manufacturing Processes:
Formed through precision stamping/roll bending to match the V-groove profile, with CNC-machined flange mating surfaces, welded or mechanically joined lugs, surface finishing (passivation/zinc plating), and torque/fitment inspection to ensure dimensional tolerance and corrosion resistance.

Quick Release T-Bolt Clamps add a quick-opening mechanism to the standard T-bolt clamp structure, allowing the clamp to be opened and refitted without completely removing the nut and bolt. You still get the strong clamping structure of a T-bolt clamp, but with less work during repeated removal and installation. This makes them practical for hose and pipe connections that need regular inspection, hose replacement or adjustment.

Yueding supplies multiple quick release T-bolt clamp designs in bulk, with material configurations such as SS201, SS304 and semi-stainless steel available depending on the specific design. You can select the size that fits your application, or send us your drawing and requirements when you need a special specification. We can further check the clamping range, band width and quick release structure with you, while materials, bolts, nuts and packaging can also be confirmed according to your order.
