BAND-IT hose fittings Germany BAND-IT model BAND-IT price

BAND-IT hose fitting is a hose connector mainly composed of three components. Metal hose fittings are used in many applications. The main component of the metal hose fitting, the bendable part, is made of braided metal wire. Metal hose fittings offer excellent performance and come in a wide variety. Different types of metal hose fittings have different characteristics, structures, and maximum temperature ratings.

Key points for BAND-IT hose fitting fabrication

Stainless steel elbows, 1. Electrodes should be kept dry during use; titanium-calcium type electrodes should be dried at 150℃ for 1 hours, and low-hydrogen type electrodes should be dried at 200-250℃ for 1 hours (do not repeat drying multiple times, otherwise the coating may crack and peel). Prevent electrode coatings from contacting oil and other contaminants to avoid increasing carbon content in the weld seam and affecting weld quality. During elbow welding, repeated heating causes carbide precipitation, reducing corrosion resistance and mechanical properties. Post-weld hardening is significant, making cracks likely. If using similar type electrodes for welding, preheating above 300℃ and post-weld slow cooling around 700℃ are required. If post-weld heat treatment cannot be performed on the weldment, chromium-nickel stainless steel electrodes should be selected. 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, resulting in better weldability. When using similar chromium stainless steel electrodes, preheating above 200℃ and post-weld tempering around 800℃ are required. If the weldment cannot undergo heat treatment, chromium-nickel stainless steel electrodes should be selected.

BAND-IT hose fitting examples

Geka coupling. Application: "Geka" couplings are specifically designed for low-pressure water pipes, serving as quick-connect fittings for spray hoses in gardening and irrigation. Structure: "Geka" quick-connect couplings have no male/female distinction and consist of left and right completely symmetrical "claw" structures. Sealing is achieved via rubber gaskets. The serrated tail design significantly increases friction with the water pipe, offering simple and durable design. Pull-type coupling. Application: Designed and manufactured according to US military standards, suitable for quick connection of various fluid flexible and rigid hoses. Composed of internal/external threads and male/female components. Wide material selection includes reinforced aluminum alloy, copper alloy, stainless steel, nylon plastic, etc., widely used in petrochemical and chemical transport fields. Structure: Pull-type quick-connect couplings consist of male and female parts. The male part has an arc shape to fit into the female part, which has a gasket at the bottom. Sealing is formed by squeezing the male part onto the gasket by pulling or pressing the levers on both sides of the female part (small sizes have a lever on only one side). Tanker truck coupling. Application: Quick-connect fittings, threaded connectors, and clamps for tanker trucks and container vehicles, developed entirely based on the German DIN series. Used at the end of tanker oil delivery pipes. Due to their simple and rapid operation design and zero-leakage stability, the tanker truck series has been popular in the European market for over fifty to sixty years. Instrumentation quick-connect coupling. Leak-free O-ring sealing can be used in vacuum and pressure systems and is interchangeable with others. Push-in connection enables quick and convenient operation, while the large-area locking device ensures a firmer grip on the hose stem. Full-flow quick-connect coupling. Maximum working pressure 414 bar (6000 psig). Made of stainless steel, carbon steel, and brass. Smooth, open bore, valve-free at both ends to minimize pressure drop and facilitate cleaning.

BAND-IT hose fitting manufacturing process

Includes a sealing ring, a connecting part, and a union nut for connecting the pipe. Therefore, the sealing ring is designed as a ring cutter with one or more cutting edges. By screwing the union nut onto the connecting part, the ring cutter can be inserted into the cavity of the connecting part, which has a conical surface. The outer side of the sealing ring has an annular reinforcement on the nut side. This annular reinforcement forms an annular surface at its transition zone towards the narrow ring section. The inclination of this annular surface, formed by the reinforced part of the ring cutter, relative to the pipe axis is 45°-90°. When fully assembled, the axial length of the annular reinforcement allows the transfer element located on the annular surface to transfer its own negative image structure or itself onto the end face of the connecting part. The transfer element has a three-dimensional profile, whose negative image can be transferred onto the surface of the connecting part. Similar to die pressing, the assembler applies pressure to imprint the negative image onto the surface of the connecting part.
