Kerb-Konus hose connector Germany Kerb-Konus model Kerb-Konus price

Kerb-Konus 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 unthreaded steel pipes to hoses, eliminating the threading process; simply screw in the fastener. They feature a compact structure and high strength. Water pipe connectors can connect unthreaded steel pipes or unthreaded equipment cable outlets to hoses, eliminating the threading process; 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 communities.

Quick connectors mainly include brass connectors, plastic connectors, and stainless steel connectors. Pneumatic quick connectors are primarily used for air piping and pneumatic tools, allowing pipeline connection or disconnection without tools. Connector specifications are divided into: PC straight connectors, PL elbow connectors, PB tee center connectors, PD tee side connectors, PXY type center connectors, PE tee reducing connectors, PE tee full-insert connectors, PY tee Y type connectors, PN series Y type reducing connectors, PV straight double-insert connectors, PU straight double-insert connectors, PG straight reducing connectors, PZ cross-type four-way full-insert connectors, PHZ cross-type four-way reducing connectors, ZR four-way threaded connectors, PLL extended right-angle connectors, PLM right-angle panel-mount connectors, PLF right-angle internal thread connectors, etc.

Kerb-Konus hose connector assembly

Pre-assembly is the most critical step for compression tube fittings, directly affecting sealing reliability. Specialized pre-assembly tools are generally required. Fittings with small pipe diameters can be pre-assembled on a bench vise. The specific procedure involves using one fitting body as the base, pressing the nut and ferrule onto the pipe. Main types include compression straight tube fittings, compression end-straight-through fittings, and compression tee tube fittings. It has been observed that even within the same batch from the same manufacturer, the depth of the tapered bore in these fitting bodies often varies, resulting in leaks, a problem that is often overlooked. The correct approach is to pre-assemble the corresponding connection end with the same type of fitting as the one connecting to one end of the pipe, which minimizes the risk of leaks. The pipe end face should be flat. After cutting the pipe, it should be ground flat on a grinding wheel or similar tool, deburred, cleaned, and blown dry with high-pressure air before use. ③ During pre-assembly, maintain coaxiality between the pipe and the fitting body as much as possible; excessive pipe misalignment will also cause sealing failure. Pre-assembly force should not be excessive; the inner edge of the ferrule should just embed into the outer wall of the pipe, and the ferrule should not show significant deformation. During pipeline connection, assemble according to the specified tightening torque. The tightening torque for ф6-1 ferrules is 64-1 15n, 16фmmr is 259n, and ф18mm is 450n. If the ferrule deforms severely during pre-assembly, it will lose its sealing function. Do not add sealants or other fillers. Some users apply sealant to the ferrule to achieve better sealing, but the sealant can be flushed into the hydraulic system, causing faults such as blocked damping holes in hydraulic components. When connecting pipelines, ensure sufficient deformation allowance for the pipe to avoid tensile stress. Avoid subjecting the pipeline to lateral forces during connection, as excessive lateral force can cause poor sealing. Complete the pipeline connection in one go; avoid multiple disconnections, as this will degrade sealing performance.

Kerb-Konus 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, manufactured using a method similar to branch connection by cutting an opening in the main pipe; the hole opened in the main pipe must match the diameter of the connected branch pipe. Welding quality requirements are strict; preheating is usually required before welding, and heat treatment is performed after welding. Their specifications and pressure ranges are the same as those for high-pressure elbows. Integrally forged high-pressure tees generally use threaded flange connections. Their specification range is DN12~DN109mm. Operating temperature: 25# carbon steel high-pressure tees are for use below 200℃, low-alloy and stainless acid-resistant steel high-pressure tees are for use below 510℃, and operating pressure is below 20.?0MPa. Common welded tee pipes have 3 types: bent pipe type, right-angle type, and flat-welded port type. 1) Same-diameter bent pipe welded tee: commonly known as a pants tee, it is made by cutting off half the circumference of the outer arm of two 90° bent pipes, then butt-welding the remaining two bent pipes together to form a same-diameter tee. 2) Right-angle tee fabrication: available in same-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-welded port tee: short tee welds, less deformation, saves pipe material, and is easy to process. 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. Then, the pipe walls on both sides of the elliptical hole are heated to approximately 900℃ and flanged outward to form a round opening.
