Timmer-Pneumatik hose fittings Germany Timmer-Pneumatik model Timmer-Pneumatik price

Timmer-Pneumatik hose fittings are connecting devices used to join metal hoses and pipes. Their models are typically determined by factors such as material, connection method, size, and applicable working pressure. Different models have different characteristics and scopes of application, such as ferrule-type metal hose fittings, flange-type metal hose fittings, and swivel-type metal hose fittings. Selecting the appropriate metal hose fitting model requires consideration of multiple factors, such as the temperature, pressure, fluid medium, service life, and connection method of the working environment. For special operating conditions such as high temperature, high pressure, and strong corrosion, it is necessary to select high-quality metal hose fitting models that can meet the requirements.

Timmer-Pneumatik hose fitting installation

Since the vibration direction of the equipment is mainly vertical up-and-down vibration, the metal hose primarily compensates for axial displacement. We know that metal hoses themselves cannot compensate for axial displacement in their natural state; such installation and usage will inevitably result in the metal hose being unable to withstand strong axial tension, leading to rupture and subsequent pipeline leakage. During installation, relative twisting occurs at both ends of the metal hose. This mainly appears when both ends of the metal hose are connected via flanges. At the installation site on ships, installation errors often cause the flange holes at the two connected ends to misalign, resulting in offset. It is mistakenly assumed that the hose fitting can compensate for torsional displacement, but in reality, the metal hose itself cannot compensate for this torsional displacement, resulting in the metal hose being twisted off and the pipeline leaking. In this case, a metal hose with a loose flange connection at one end can be selected for connection. During installation, there is a large radial offset between the two ends of the metal hose. Although the metal hose itself can compensate for lateral displacement, if there is a large relative radial displacement between its two ends during installation, the actual compensatable amount in that direction will be reduced. This may cause the required compensation in that direction during use to exceed the actual compensatable amount of the hose in that direction, leading to fatigue damage and failure of the metal hose.

Timmer-Pneumatik hose fitting usage

How to ensure sealing in the connection between hose fittings and hoses? The connection between hose fittings and hoses is simple, but ensuring the seal is critical. So, how is the seal achieved in the connection between hose fittings and hoses? Generally speaking, regardless of the variety of hose fittings, the appropriate transition fitting should be selected based on the type of hose fitting. If the hose is an ordinary water pipe, a transition fitting with internal threads on one end and a spigot for inserting the water pipe on the other should be used, secured with a hose clamp. If both ends of the hose have internal threads, the transition fitting should have internal threads on one end and external threads on the other. If both ends of the hose have external threads, a straight-through internal thread fitting should be used. Generally, hydraulic quick-change fittings must withstand high pressure, so high-pressure oil hoses are used in most cases. The two ends of the oil hose are mostly made with internal threads, so they can be connected directly. As for hydraulic fittings, no other rubber rings are needed for sealing; the product itself has one concave end and one convex end, achieving a complete seal upon connection.

Timmer-Pneumatik hose fitting assembly

Pre-assembly is the most important step for ferrule-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 as the base body to press the nut and ferrule onto the pipe. Main types include ferrule-type straight pipe fittings, ferrule-type end straight-through fittings, and ferrule-type tee pipe fittings. The author has found that even within the same batch from the same manufacturer, the depth of the tapered hole in these fitting bodies often varies, resulting in leakage, a problem that is often overlooked. The correct practice is to pre-assemble the corresponding connection end with the same type of fitting as the one used to connect to one end of the pipe, thereby minimizing the risk of leakage. The pipe end face should be flat. After cutting the pipe, it should be ground flat on tools such as a grinding wheel, deburred, cleaned, and blown dry with high-pressure air before use. ③ During pre-assembly, try to maintain the coaxiality of the pipe and the fitting body; excessive deviation of the pipe will also cause sealing failure. The pre-assembly force should not be too great; the inner edge of the ferrule should just embed into the outer wall of the pipe, and the ferrule should not show obvious deformation. During pipeline connection, assemble according to the specified tightening torque. The tightening torque for ф6-1 ferrules is 64-1 15n, for 16фmmr it is 259n, and for ф18mm it is 450n. If the ferrule is severely deformed during pre-assembly, it will lose its sealing function. Do not add sealants or other fillers. Some people apply sealant to the ferrule to achieve better sealing results, but the sealant gets flushed into the hydraulic system, causing failures such as clogging of damping holes in hydraulic components. When connecting pipelines, ensure the pipe has sufficient deformation allowance to avoid subjecting the pipe to tensile forces. When connecting pipelines, avoid subjecting them to lateral forces; excessive lateral forces will cause poor sealing. When connecting pipelines, complete the connection in one go to avoid multiple disassemblies, which will also degrade sealing performance.
