Drumag hose connector Germany Drumag model Drumag price

Drumag hose connectors consist of a nut, metal ring, sealing ring, and the body. They offer waterproofing, dirt resistance, explosion-proof protection, and corrosion resistance, becoming an essential part of industrial piping. In general, each pipeline has different requirements for metal hoses; plastic-coated metal hose tee connectors and corresponding bimetallic composite pipes are used for different materials and construction environments.

Drumag hose connector features

Female straight connector, a terminal fitting commonly used for directional connections in plumbing installations. Male straight connector, a fitting commonly used for connections in plumbing installations. Its external thread is on the outside, opposite to the internal thread elbow. Internal threads are classified by angle, including 45° and 90°, and also include other non-standard angle elbows such as 60° according to engineering needs. Materials for internal thread elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. External thread elbows are formed by hot pushing or stamping: 1. The hot push elbow forming process uses a dedicated elbow pushing machine, core mold, and heating device to push the blank mounted on the mold forward, where it is heated, expanded, and bent into shape during movement. 2. Stamped forming of elbows was 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 Currently, it has been replaced by hot pushing or other forming processes in the production of common specification elbows, but for certain specifications, due to small production quantities or wall thicknesses that are too thick or too thin.

Drumag hose connector selection

Y type tee metal hose connector, with one end connecting to thin-wall steel electrical conduit and the other two ends connecting to metal hoses via metal connectors. The metal connectors are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated. The structure is compact, pore-free, and high-strength. It provides reliable connection with metal hoses and has an attractive appearance. Non-standard metal hose connectors and special metal connectors can be customized. T type tee metal hose connector, with one end connecting to thin-wall steel electrical conduit and the other two ends connecting to metal hoses via metal connectors. The metal connectors are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated. The structure is compact, pore-free, and high-strength. Reliable connection with metal hoses and attractive appearance. 90 degree elbow connector: Thread specification: After engagement with imperial threads, it forms a 90 degree angle with the enclosure box. Made of thickened zinc alloy, with attractive appearance, compact structure, and high strength. In addition to the standard specifications below, sizes and thread standards can be arbitrarily changed according to requirements.

Drumag hose connector classification

Connector structures are generally divided into three main categories: screw-type, flange-type, and quick-release type. 1. Screw-type: For metal hose connectors with nominal diameters below 50 mm operating under higher working pressures, screw-type is predominantly used. After tightening the threads, the internal and external tapered surfaces of the two connectors fit tightly to achieve sealing. The cone angle is generally 60 degrees, though 74 degrees is also used. This structure offers good sealing, but concentricity of the two mating parts must be ensured during installation. To address issues frequently encountered in practical engineering, such as repeated disassembly/assembly and difficulty in achieving concentricity, the connector can be designed with a tapered surface mating with a spherical head. 2. Flange-type: For metal hose connectors with nominal diameters above 25 mm operating under general working pressures, flange-type is predominantly used. It seals via a tongue-and-groove fit. A loose flange, capable of radial rotation and axial sliding, connects the two bodies under the tension of tightening bolts. This structure offers good sealing performance but is difficult to manufacture, and the sealing surface is prone to damage. For special occasions requiring quick release, the holes for the tightening bolts can be slotted to create a quick-release flange. 3. Quick-release type: For various metal hose connectors with nominal diameters below 100 mm, quick-release type is generally used under conditions requiring rapid assembly and disassembly. It commonly uses an "O"-shaped sealing ring made of fluoroplastic or special rubber for sealing. When the handle is moved by a certain angle, it acts like the claws of a multi-start thread being locked; the tighter the "O"-shaped sealing ring is compressed, the better the sealing performance. This structure is most suitable for fire scenes, battlefields, and other occasions requiring rapid assembly and disassembly. A set of connectors can be joined or disconnected within seconds without any special tools.
