The Elastomeric Tube Swaging Process

This process is widely used in both commercial and military aircraft industries for the fabrication of tubing assemblies in hydraulic, fuel, oxygen, and similar fluid distribution systems. Today, elastomeric swaging is employed to create tubing assemblies for both low and high-pressure fluid systems made from materials such as aluminum, steel, stainless steel alloys, and titanium. Unlike thermal joining methods like brazing or welding, elastomeric swaging produces fluid-tight connections without compromising the material’s strength. It also offers high-quality mechanical tube fitting attachments, avoiding issues like wall thinning and stress concentrations that can occur with mechanical roller swaging or older bite-type designs. Beyond aerospace, our internal elastomeric swage machines and support tooling are now being introduced to various other industries. These include marine engines, automotive, trucks, refrigeration, air conditioning, motorcycles, motor homes, construction equipment, and tractors. The process involves cold forming, where extremely high radial forces are applied to the internal surface of a tubular member. This displaces the tubing into grooves on an external end fitting or into a shaped die cavity to create specific tube end forms, such as beads. The internal swaging forces are generated by the controlled linear movement of a high-strength drawbolt that compresses an elastomeric expander against a static retainer ring. During the swaging cycle, this controlled compression forces the tube wall radially into internal circumferential grooves on the end fitting skirt, resulting in a strong, leak-proof mechanical attachment. The tube end fitting is contained within a precision-matched split die cavity, which provides a reactionary force during the forming process and prevents distortion of the fitting. Elastomeric swaging is a fast, efficient, and practical method for attaching tube fittings. It eliminates costly post-processing operations such as radiographic or ultrasonic inspections, which are often required for welded or brazed connections. We manufacture all forming dies and swage tooling for each of our elastomeric tube swagers. Pricing for these items is quoted based on customer requirements and order quantity. Each machine is designed to meet all applicable safety standards and can be customized for electrical compatibility. An operation and safety training package is included with every purchase, and a six-month warranty covers all parts and workmanship. The internal elastomeric swage fittings were developed to provide a simple yet reliable method for attaching separable end fittings to rigid tubes in demanding aerospace environments. These fittings offer a lightweight and cost-effective alternative to traditional methods like welding or brazing. **Advantages of Internal Swaging** Internal swaging is a mechanical method of attaching fittings to tubing. It works by forming the tubing outward into grooves within the fitting. This technique offers several benefits: - No special tube end preparation (cleaning or sizing) is required. - Fabrication is very quick, taking only seconds per connection. - No X-ray inspection is necessary. - No flushing or ball-check tests are needed. - It reduces scrap rates significantly. - It improves fatigue performance compared to brazed joints. - There are no heat-affected zones or heat-induced distortions. - No stress-relieving is required after the process. These advantages can lead to significant cost savings in installation and maintenance. The use of Eaton internal swage fittings is ideally compatible with CAD/CAM systems for tube assembly production. Mechanical attachment at room temperature is especially beneficial in situations where flammability is a concern. **Fitting Features** - Fittings are manufactured from high-strength alloys, including 15-5 CRES, 7075 Aluminum, and 6AL-4V Titanium. - Flared fittings feature a machined metal sealing surface that prevents tube flare cracking. - A two-angle face design allows up to 4° angular misalignment for a line-contact seal. - Various flareless styles are available, compatible with all current flareless systems. - Lipseal fittings provide excellent sealing due to a flexible beam surface and maximum interface clearance. - Available in sizes ranging from 1/4" (6.35 mm) to 1-1/2" (38 mm). **Internal Swaging Technique**

Weld Materials

1.Welding materials

In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.


The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.

Welding can be applied in different kinds of industries such as building and construction, oil and gas, marine, power generation, steel, mine tools, automobile, transportation and etc.
