Buhler hose connector Germany Buhler model Buhler price

Buhler 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.

Buhler hose connector classification

Connector structures are broadly divided into three categories: spiral, flange, and quick-connect. 1. Threaded type: For metal hose connectors with nominal diameters below 50 mm, threaded types are predominantly used under high working pressure conditions. 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 common issues in practical engineering such as repeated assembly/disassembly 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, flange types are predominantly used under general working pressure conditions. Sealing is achieved via a tongue-and-groove fit. Loose flanges, which can rotate radially or slide axially, connect the two bodies under the tension of tightening bolts. This structure provides good sealing performance but is difficult to manufacture, and the sealing surfaces are prone to damage. For special applications requiring quick release, the holes for the tightening bolts can be slotted to create a quick-release flange. 3. Quick-connect type: For various metal hose connectors with nominal diameters below 100 mm, quick-connect types are generally used where rapid assembly and disassembly are required. They commonly use "O"-shaped sealing rings made of fluoroplastics or special rubber. 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 situations requiring rapid installation and removal. A set of connectors can be joined or disconnected within seconds without any special tools.

Buhler hose connector material classification

High-pressure tees. There are two common types of high-pressure tees: welded high-pressure tees and integrally forged high-pressure tees. Welded high-pressure tees are made from high-quality high-pressure steel pipes, using a manufacturing method similar to branch connection by cutting into the main pipe; the hole opened in the main pipe must match the diameter of the connected branch pipe. Welding quality requirements are strict, typically requiring preheating before welding and heat treatment after welding, with specifications and pressure ranges similar to high-pressure elbows. Integrally forged high-pressure tees generally use threaded flange connections. Their specification range is DN12~DN109mm. Service temperature: for 25# carbon steel high-pressure tees, it is below 200°C; for low-alloy and stainless acid-resistant steel high-pressure tees, it is below 510°C. Operating pressure is below 20.?0MPa. There are 3 common types of welded tee pipes: elbow type, right-angle type, and flat-weld opening type. 1) Equal-diameter elbow welded tee: Commonly known as pants-leg pipe, it is made by cutting off half the circumference of the outer arm of two 90° elbow pipes, then butt-welding the remaining two elbows together to form an equal-diameter tee. 2) Right-angle tee fabrication: Available in equal-diameter and reducing types. During fabrication, development drawings are drawn based on two intersecting cylindrical surfaces, typically cut using an oxy-acetylene flame cutter, and finally welded. 3) Flat-weld opening tee: The tee weld seam is short, deformation is minimal, pipe material is saved, and processing is simple. The fabrication method involves cutting an elliptical hole in a straight pipe, where the minor axis of the ellipse equals 2/3 of the branch pipe's outer diameter, and the major axis equals the branch pipe's outer diameter. The pipe walls on both sides of the elliptical hole are then heated to approximately 900°C and flanged outward to form a round opening.

1. Since most fittings are used for welding, to improve welding quality, the ends are machined with bevels, leaving a specific angle and edge. This requirement is quite strict, with regulations on edge thickness, angle, and tolerance range. Surface quality and mechanical properties are basically the same as the pipe. To facilitate welding, the steel grade of the fittings is the same as that of the connected pipes. 2. All fittings undergo surface treatment, where oxide scale on the inner and outer surfaces is removed by shot blasting, followed by the application of anti-corrosion paint. This is required for export purposes and, domestically, to prevent rust and oxidation during transportation. 3. Packaging requirements: For small fittings, such as those for export, wooden crates are required, approximately 1 cubic meters in volume. Regulations state that the number of elbows in such crates should not exceed one ton. Nesting is allowed (i.e., smaller items inside larger ones), but the total weight generally must not exceed 1 tons. For large items y, individual packaging is required, such as for 24″ items. Additionally, packaging marks must indicate dimensions, steel grade, batch number, manufacturer trademark, etc.
