MAPRESS hose connector Germany MAPRESS model MAPRESS price

MAPRESS hose connectors are components in hydraulic systems that connect high-pressure oil hoses to other high-pressure oil hoses. Hydraulic pipe fittings can be further classified into hydraulic hoses, high-pressure ball valves, quick-connect couplings, compression-type pipe fittings, welded pipe fittings, high-pressure hoses, transition pipe fittings, tee pipe fittings, non-standard pipe fittings, flared pipe fittings, right-angle pipe fittings, rotary pipe fittings, quick-connect couplings, stainless steel pipe fittings, and copper fittings.

MAPRESS hose connector applications

Elbows are commonly used connecting fittings in plumbing installations, used for connections at pipe bends to change the direction of the pipeline. Other names: 90° elbow, right-angle bend, air bend, stamped elbow, pressed elbow, machined elbow, welded elbow, etc. Application: Connect two pipes with the same or different nominal diameters to allow the pipeline to make 90°, 45°, 180°, and turns of various degrees. A bending radius less than or equal to 1.5 times the pipe diameter is classified as an elbow; greater than 1.5 times the pipe diameter is classified as a bend. It is a commonly used connecting fitting in pipeline installation, connecting two pipes with the same or different nominal diameters to allow the pipeline to turn at a specific angle, with a nominal pressure of 1-1.6Mpa.

MAPRESS hose connector classification

Classification by pipe diameter: For equal-diameter tees, the ends of all branch connections are of the same size; for reducing tees, the main pipe connection sizes are identical, while the branch pipe connection size is smaller than the main pipe connection size. Classification by process: 1. Hydraulic bulging: The hydraulic bulging of a tee is a forming process in which the branch pipe is bulged out through axial compensation of the metal material. The process involves using a specialized hydraulic press to inject liquid into a pipe blank with a diameter equal to that of the tee. Two horizontal side cylinders of the hydraulic press move synchronously toward the center to compress the pipe blank. As the pipe blank is compressed, its volume decreases, causing the pressure of the liquid inside to rise. When the pressure required to bulge out the branch pipe is reached, the metal material flows along the mold cavity under the combined action of the side cylinders and the internal liquid pressure, thereby forming the branch pipe. The hydraulic bulging process for tees allows one-time forming with relatively high production efficiency; however, the wall thickness of both the main pipe and the shoulder increases. Since the hydraulic bulging process for seamless tees requires equipment with a large tonnage, it is mainly used domestically for manufacturing standard-wall tees smaller than DN400. Suitable forming materials include low-carbon steel, low-alloy steel, and stainless steel with relatively low tendencies for work hardening, as well as some non-ferrous metals such as copper, aluminum, and titanium. 2. Hot pressing forming: Tee hot pressing forming involves flattening a pipe blank larger than the tee diameter to approximately the tee diameter, and opening a hole at the location where the branch pipe will be drawn. The pipe blank is heated, placed into a forming mold, and a punch for drawing the branch pipe is inserted into the blank. Under pressure, the pipe blank is radially compressed. During radial compression, the metal flows toward the branch pipe direction and forms the branch under the stretching action of the punch. The entire process forms the tee through radial compression of the pipe blank and stretching of the branch area. Unlike hydraulic bulging, the metal for the branch pipe in hot-pressed tees is compensated by the radial movement of the pipe blank, so it is also referred to as the radial compensation process. Because the tee is pressed after heating, the equipment tonnage required for material forming is reduced. Hot-pressed tees have wide material adaptability, suitable for low-carbon steel, alloy steel, and stainless steel; this forming process is typically used for large-diameter tees and those with thicker walls. Classification by material: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon chrome asphalt, pvc, etc. Classification by manufacturing method: top-made, pressed, forged, cast, etc.

MAPRESS hose connector installation

1. Clean impurities: When installing water pipe connectors, thoroughly remove all impurities from inside the pipeline. This helps prevent damage to the valve core, jamming, blockage, and leakage. Also clean the surface to ensure no residual building materials remain. 2. Do not apply excessive force when switching: For any type of household water pipe connector product, excessive force is not required when switching; gentle twisting or toggling is sufficient. Even for traditional household water pipe connectors, significant effort is not needed to tighten them completely. In particular, do not use the handle as a support or handrail. For products equipped with screen filters at the water outlet, disassemble and rinse after a period of use to remove impurities. 3. Regular cleaning: Household water pipe connectors that are unused for long periods may experience incomplete closure, leakage, loose handles, or leaking connections. Typically, consumers can resolve these issues themselves. 4. Keep household water pipe connectors extended: The metal hose of the shower head for household water pipe connectors should remain in a naturally extended state; do not coil it around the faucet when not in use. Additionally, whether in use or not, ensure that the connection between the hose and the valve body does not form dead angles to prevent breaking or damaging the hose.
