M & C hose fittings, German M & C models, M & C prices

M & C hose fittings are also known as pipe tees, tee fittings, or tee connectors. They are mainly used to change the direction of fluid flow at branch points 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 alloy, 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. Tee pipes are made of plastic, glass, cast steel, cast copper, and cast iron, primarily because the media they transport differ. Tee pipes have equal-diameter ports and reducing ports, mainly used to change the direction of fluid flow. They are applied in fields such as medicine, water conservancy, and construction.

M & C hose fitting installation

Dual-line main and branch pipes: From the lubrication pump to the oil inlet ports of all distributors, these lines withstand relatively high pressure. Cold-drawn seamless steel pipes are usually used, made of 10 or 15 grade steel. Pipes with severe rust must not be used. Oil supply pipes: From the distributors to the oil inlet ports (bearing seat oil holes) of all lubrication points, these lines withstand relatively low pressure. Drawn copper tubes are usually used, facilitating piping when routing involves bends. Cold-drawn seamless steel pipes or stainless steel pipes are also used. Hose fittings are used for connections at moving parts. Piping should avoid areas with high-temperature radiation or cooling water spray, i.e., places with excessively high or low temperatures, especially at hose fittings. Piping layout must not interfere with the operation of the host machine and other equipment; it must be safe, reliable, and convenient for work, observation, and maintenance. Piping should be laid out horizontally and vertically, neatly and aesthetically. Minimize bends or small-angle bends; use large-radius arcs to reduce oil flow resistance. If conflicts occur during installation, smaller pipes should yield to larger pipes, and low-pressure pipes should yield to high-pressure pipes. Crossing pipes must not touch each other and should be separated by a certain distance. Joints of parallel pipes should be staggered to avoid affecting installation and disassembly. To facilitate disassembly and cleaning, union joints should be installed appropriately, but their use should be minimized to reduce the possibility of leakage. Determine the pipe length on-site based on the piping path determined in item 8.2, taking into account the influence of the bending radius. Consider the impact of inserting various pipe fittings into the pipeline. Determine, cut, and pre-install pipe lengths segment by segment to facilitate on-site adjustments according to actual conditions. If all pipes are cut at once, accumulated errors will make piping difficult. Utilize cut short pipes wherever short sections are needed. If necessary, use straight couplings to extend length, but minimize the number of joints on pipe sections.

M & C hose fitting precautions

Do not use quick-release hose fittings for applications other than fluid transfer. Do not use them with fluids other than the specified compatible fluids. Do not exceed the maximum operating pressure during use. Do not use outside the specified temperature range to prevent deformation of sealing materials, which can easily lead to leaks. Do not subject the fittings to artificial impact, bending, or stretching to prevent damage. Do not use in environments contaminated with metal powder, sand, or dust. Using quick-release fittings in such harsh conditions can ensure long service life. Accumulation of debris can cause poor performance or leakage. Do not disassemble the quick-release fittings.

M & C hose fitting selection criteria

1. Type of fluid and temperature (select quick-release fittings with body and sealing materials suitable for the fluid type and temperature). The suitable body and sealing materials vary depending on the fluid. For example, for air, steel quick-release fittings are recommended; for water, choose brass or stainless steel. 2. Fluid pressure (select quick-release fittings with pressure resistance suitable for the fluid pressure). Fluid pressure is also a key factor in selecting quick-release fittings. Hydraulic quick-release fittings are standardized in the range of 5.0Mpa (51kgf/cm&²) to 68.6Mpa (700kgf/cm&²). The structure of the quick-release fitting differs according to its pressure resistance characteristics. 3. Structure of the automatic shut-off valve (select quick-release fittings with valve structures suitable for the piping application). Valve structures include dual shut-off, single shut-off, and dual open types. Note that except for the dual shut-off type, fluid will flow out from the piping upon separation. 4. Operating environment of the quick-release fitting (select quick-release fittings with structures and materials suitable for the operating environment). Consider the humidity, dust conditions, and corrosiveness of the environment when selecting the type, body material, and sealing material of the quick-release fitting. 5. Ensure that the connection threads of the selected quick-release fittings are consistent. When using products from different brands, it is best to use male and female ends from the same brand. If cross-brand usage is necessary, consult the supplier's technical personnel before use to confirm compatibility. 6. Installation shape and dimensions. Determine the model and material of the quick-release fitting, and specify the assembly shape and dimensions corresponding to the piping characteristics. Note that dimensions are related to fluid flow rate.
