trumpf hose connector Germany trumpf model trumpf price

trumpf hose connectors are components used to connect water pipes. Connectors can be classified by usage method into: external thread end-connecting water pipe connectors, compression-type water pipe connectors, and self-locking water pipe connectors. External thread end-connecting water pipe connectors are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure, no pores, and high strength. Compression-type water pipe connectors can connect seamless steel pipes to hoses, eliminating the need for threading; simply screw in the fastener. They have a compact structure and high strength. Water pipe connectors can connect seamless steel pipes or unthreaded equipment outlets to hoses, eliminating the need for threading; they are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure and high strength. Widely used in high-end buildings, hotels, hospitals, office towers, stadiums, museums, government agencies, villas, and residential complexes.

trumpf hose connector types

1, classified by pipe fitting diameter, generally includes equal-diameter tees and reducing tees. 2, classified by branch direction, includes straight tees and lateral tees. 3, classified by material, includes carbon steel, alloy steel, stainless steel, copper, and pvc tees. 4, classified by connection method, includes standard tees, threaded tees, compression tees, and socket-weld tees. 5, tee designation methods are as follows: For an equal-diameter tee, such as "T6" tee, it indicates an equal-diameter tee with an outer diameter of 6 inches. 6, for a reducing tee, for example, "T4×4×3.5" indicates a reducing tee with a nominal diameter of four inches and a reduced diameter of 3.5 inches. The pressure rating is the same as that of elbows, and the specification range is also the same.

trumpf hose connector manufacturing process

Stamping forming: Stamping forming of elbows was the earliest forming process applied to the mass production of seamless elbows. In the production of common specification elbows, it has been replaced by hot pushing or other forming processes. However, for certain elbow specifications, due to small production quantities, excessively thick or thin wall thicknesses, or special product requirements, it is still in use. Stamping forming of elbows uses pipe blanks with an outer diameter equal to that of the elbow, which are directly pressed into shape in a die using a press. Before stamping, the pipe blank is placed on the lower die, and the inner mandrel and end die are inserted into the blank. The upper die moves downward to begin pressing, forming the elbow through the constraint of the outer die and the support of the inner die. Compared with the hot pushing process, the surface quality of stamping forming is inferior. During the forming of stamped elbows, the outer arc is in a tensile state, with no excess metal from other areas to compensate, so the wall thickness at the outer arc is reduced by approximately 10%. However, due to its suitability for single-piece production and low cost, the stamped elbow process is mostly used for small-batch, thick-walled elbow manufacturing. Stamped elbows are divided into cold stamping and hot stamping, with the choice typically based on material properties and equipment capabilities. The cold extrusion forming process for elbows uses a specialized elbow forming machine. The pipe blank is placed in the outer die, and after the upper and lower dies close, the blank moves through the gap reserved between the inner and outer dies under the push of a push rod, completing the forming process. Elbows manufactured using the internal and external mold cold extrusion process have an attractive appearance, uniform wall thickness, and small dimensional deviations. Therefore, this process is often used for forming stainless steel elbows, especially thin-walled stainless steel elbows. This process requires high precision for the internal and external molds and has strict requirements for the wall thickness deviation of the pipe blanks.

trumpf hose connector advantages

Compression-type copper tube fittings—Advantages: simple structure, reliable sealing performance, ease of use, fine manufacturing, and lightweight, attractive appearance. No gaskets required, no welding needed, material savings, and good performance in repeated assembly and disassembly. Since stainless steel compression tube fittings cannot be welded, this reduces the impact of pipeline impurities on system performance. Therefore, stainless steel compression tube fittings are increasingly widely used in hydraulic and pneumatic equipment pipelines using oil and gas as media, particularly suitable for environments with fire hazards, high-altitude operations, and frequent assembly/disassembly. They are currently being vigorously promoted and used in China. Compression-type copper tube fittings—Structure and principle: The basic structure of this type of fitting is relatively simple, consisting of only three basic parts: the fitting body, the ferrule, and the nut. The main component is the ferrule, which is a metal ring with a cutting edge at the front. International standard GB3764-83 recommends a unified I type shape for the cutting edge.
