CONRAD hose connector Germany CONRAD model CONRAD price

CONRAD hose connectors are also known as pipe fittings tees, tee fittings, or tee joints. They are mainly used to change the direction of fluid flow and are installed where branch pipes diverge from the main pipeline. They can be classified by pipe diameter. They are generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon-chromium alloys, pvc, and other materials. A tee pipe is a type of chemical pipe fitting. It is a pipe connector with three openings: one inlet and two outlets, or two inlets and one outlet. The materials for tee pipes include plastic, glass, cast steel, cast copper, and cast iron, mainly due to the different media they transport. Tee pipes have equal-diameter and reducing ports, primarily used to change the direction of fluid flow. They are applied in fields such as medicine, water conservancy, and construction.

CONRAD hose connector assembly

Pre-assembly is the most critical step for bite-type pipe 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 method involves using one fitting body as the base, pressing the nut and bite ring onto the pipe. Main types include bite-type straight-through pipe fittings, bite-type end-straight-through fittings, and bite-type tee pipe fittings. It has been observed that even within the same batch from the same manufacturer, the depth of the tapered hole 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, thereby minimizing the risk of leaks. The pipe end face should be flat. After cutting, the pipe should be ground flat on tools such as a grinding wheel, deburred, cleaned, and blown dry with high-pressure air before use. During pre-assembly, maintain coaxiality between the pipe and the fitting body as much as possible; excessive pipe skewing will also cause sealing failure. The pre-assembly force should not be too high; the inner edge of the bite ring should just embed into the outer wall of the pipe, and the bite ring should not show obvious deformation. During pipeline connection, assemble according to the specified tightening torque. The tightening torque for ф6-1 bite rings is 64-1 15n, 16фmmr is 259n, and ф18mm is 450n. If the bite ring deforms severely during pre-assembly, it will lose its sealing function. Do not add sealants or other fillers. Some users apply sealant to the bite ring to achieve better sealing, but the sealant can be flushed into the hydraulic system, causing faults such as blockage of damping holes in hydraulic components. When connecting pipelines, ensure sufficient deformation allowance for the pipe to avoid tensile forces. Avoid subjecting the pipeline to lateral forces during connection, as excessive lateral force will cause poor sealing. Complete the pipeline connection in one go to avoid multiple disconnections, which will also degrade sealing performance.

CONRAD hose connector selection

Metal hose connectors consist of a metal hose body, a stainless steel wire mesh braid, and connector fittings. They can compensate for certain relative displacements and provide vibration reduction and noise dampening effects. However, improper selection will not only fail to provide vibration isolation and noise reduction but may also lead to pipeline leaks or even equipment failures due to damage to the metal hose. Selection of metal hoses mainly involves the correct choice of parameters such as nominal diameter, connection type, working pressure, temperature correction, minimum bending radius, and hose length. Nominal diameter, connection type, and working pressure are directly determined by pipeline system requirements and generally do not pose problems. It is worth noting that when selecting the design pressure of the hose (which should be greater than the system working pressure), it should not be set too high, because as the pressure-bearing capacity of the hose increases, its bending capability decreases significantly. Temperature correction and minimum bending radius are fixed for the product and provided by the manufacturer. Problems often arise in the selection of metal hose length; hoses that are too long can cause instability, increase flow resistance, and lead to additional mechanical damage and vibration issues. Hoses that are too short may fail to achieve compensation, vibration reduction, and noise elimination purposes, and may also cause excessive bending stress, affecting service life.

CONRAD hose connector structure

A compression tube fitting consists of three parts: the fitting body, the ferrule, and the nut. When the ferrule and nut are placed on the steel tube and inserted into the fitting body, tightening the nut causes the outer side of the ferrule's front end to seat against the conical surface of the fitting body, while its inner edge uniformly bites into the seamless steel tube, forming an effective seal. Basic description: compression tee terminal fittings, also known as tee terminal fittings, compression reducing tees, and compression equal tees. Common specifications: 10-10, 6-6, 8-8, G1/2-8, 14-14, 22-22, 8-6, 10-8, 14-10. Common materials: 20#, 1Cr18Ni9Ti, 304, 316, 316L. Material information: nominal pressure: 2.5MPa, 16Mpa, 25MPA, 64MPA. Suitable media: oil, water, gas, and other non-corrosive or corrosive media. Tubing: seamless steel tubes with ordinary-grade precision, from Ф4 to Ф42. Tapered pipe threads: ZG, R, G, PT, NPT, etc. Applications: widely used in many industries such as chemical, pharmaceutical, petroleum, scientific experimentation, and electrical engineering.
