AFLEX hose fittings, Germany AFLEX models, AFLEX prices

AFLEX hose fittings are high-quality flexible pipelines in modern industrial piping systems. They mainly consist of bellows, braided mesh, and fittings. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape. The outer braided mesh of the bellows is woven from stainless steel wire or steel strip according to specific parameters. The fittings or flanges at both ends of the hose are matched to the customer's pipeline fittings or flanges. The bellows of the hose are formed by high-precision plastic processing of ultra-thin-walled seamless or welded stainless steel pipes. The elastic characteristics of the bellows profile give the hose excellent flexibility and fatigue resistance, allowing it to easily absorb cyclic loads from various motion deformations, especially compensating for large displacements in piping systems.

AFLEX hose fitting selection criteria

1, fluid type, and temperature (please select quick couplings with body and seal materials suitable for the fluid type and temperature). Depending on the fluid, the suitable body and seal materials differ. For example, for air, steel quick couplings are recommended; for water, choose brass or stainless steel. 2, liquid pressure (please select quick couplings with pressure ratings suitable for the fluid pressure). Fluid pressure is also key to selecting quick couplings. Hydraulic quick couplings are serialized between 5.0Mpa (51kgf/cm) and 68.6Mpa (700kgf/cm), and their construction varies according to pressure resistance characteristics. 3, automatic shut-off valve construction (please select quick couplings with valve constructions suitable for piping applications). Valve constructions include two-way shut-off, one-way shut-off, and two-way open types. Note that except for the two-way shut-off type, fluid will flow out from the piping upon disconnection. 4, operating environment of the quick coupling (please select quick couplings with constructions and materials suitable for the operating environment). Consider humidity, dust conditions, and corrosive environments when selecting the type, body material, and seal material of the quick coupling. 5, ensure the connection threads of the selected quick coupling are consistent. When using products from different brands, it is best to use male and female connectors from the same brand. If cross-brand usage is necessary, consult the supplier's technical staff beforehand to confirm compatibility before use. 6, installation shape and dimensions. Determine the model and material of the quick coupling, and specify the assembly shape and dimensions corresponding to the piping characteristics. Note that dimensions are related to fluid flow rate.

AFLEX hose fitting characteristics

Female straight connector, a terminal pipe fitting commonly used for directional connections in plumbing installations. Male straight connector, a pipe fitting commonly used for connections in plumbing installations. Its threaded port is on the outside, opposite to the female elbow. Female elbows are classified by angle into 45° and 90°. Additionally, other non-standard angle elbows such as 60° are included based on engineering requirements. Materials for female elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. Male elbows are formed by hot pushing or stamping: 1, the hot push elbow forming process uses specialized elbow pushing machines, mandrels, and heating devices to push the blank mounted on the mold forward, where it is heated, expanded, and bent into shape during movement. 2, stamping is the earliest forming process applied to mass production of seamless elbows. Currently, it has been replaced by hot pushing or other forming processes in the production of common specification elbows, but it is still used for certain specifications due to small production quantities or excessively thick or thin wall thicknesses.

AFLEX hose fitting manufacturing points

Stainless steel elbows. 1, keep welding rods dry during use. Titanium-calcium type rods should be dried at 150℃ for 1 hours, and low-hydrogen type rods should be dried at 200-250℃ for 1 hours (do not repeatedly dry, otherwise the coating may crack and peel). Prevent the rod coating from sticking to oil and other contaminants to avoid increasing carbon content in the weld and affecting weld quality. During elbow welding, repeated heating precipitates carbides, reducing corrosion resistance and mechanical properties. Post-weld hardening is significant, making cracks likely. If welding with similar types of rods, preheating above 300℃ and slow cooling after welding at around 700℃ are required. If post-weld heat treatment cannot be performed, use chromium-nickel stainless steel welding rods. 2, to improve the corrosion resistance and weldability of stainless steel elbows, appropriate amounts of stabilizing elements such as Ti, Nb, and Mo are added. Weldability is somewhat better. When using similar chromium stainless steel welding rods, preheating above 200℃ and tempering after welding at around 800℃ are required. If the weldment cannot undergo heat treatment, use chromium-nickel stainless steel welding rods.
