ETP-HYLOC hose connector Germany ETP-HYLOC model ETP-HYLOC price

ETP-HYLOC hose connectors are fittings that allow connection or disconnection of pipelines without tools. Exchange function: accessories for pneumatic and hydraulic tools, cylinders, hydraulic cylinders, and machinery related to metal molds. Maintenance function: cooling devices for computers, maintenance of oil cylinders in die-casting machines. Test function: testing for vacuum, pressure resistance, leakage, operation, etc. Conveying function: conveying and handling of solids such as bolts and nuts, as well as electrical conductivity. Filling function: inert gases, nitrogen, PG, carbonic acid. Time and labor saving: when disconnecting and connecting oil lines via quick connectors, the operation is simple, saving time and manpower. Oil saving: when the oil line is disconnected, the check valve on the quick connector can close the oil line, preventing oil from flowing out and avoiding loss of oil and oil pressure. Environmental protection: when quick connectors are disconnected and connected, oil does not spill, protecting the environment. Equipment modularization for convenient transport: large equipment or hydraulic tools that need to be portable can be disassembled using quick connectors for transport, and then assembled for use at the destination.

ETP-HYLOC hose connector functions

The function of a rotary joint is to serve as a sealing device for connecting pipes to input liquid into rotating or reciprocating equipment and discharge it from there. In the case of bent pipes, especially metal hoses, a considerable total length is required for the stroke due to the large bending radius. By installing a rotary joint at the root, it can be completed with the shortest hose length, which not only saves space but can also be used to absorb hose twisting depending on the method of use. Hydraulic and water piping systems can use entire sets of rotary joints to accommodate complex movements. They can be used with confidence in locations where hoses are difficult to install or where significant leakage is a concern, and under harsh environmental conditions such as high temperature and high pressure. For example, when a boiler burner is ignited, rotary joints installed for inserting oil and steam piping can be used without problems even under harsh conditions of high temperature, high pressure, and complex movements. In summary, rotary joints can be equipped on cylindrical, drum-shaped, frustum-shaped, and spherical rotating equipment, as well as equipment that reciprocates or oscillates at any angle, using gases and liquids such as steam, water, oil, gas, air, brine, and ammonia for heating, drying, and cooling, as well as pneumatic and hydraulic equipment used for clamping, braking, and gripping.

ETP-HYLOC 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 tee branch 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 the manufacture of standard-wall tees with diameters less 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: Tee hot pressing involves flattening a pipe blank with a diameter larger than that of the tee to approximately the tee's diameter, then opening a hole at the location where the branch will be drawn. The pipe blank is heated, placed into a forming die, and a punch for drawing the branch is inserted into the blank. Under pressure, the pipe blank is radially compressed. During radial compression, the metal flows toward the branch 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 of a hot-pressed tee 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 and are suitable for low-carbon steel, alloy steel, and stainless steel; this forming process is typically used for tees with large diameters and thicker walls. Classification by material: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon-chromium alloy, pvc, etc. Classification by manufacturing method: top-made, pressed, forged, cast, etc.

ETP-HYLOC hose connector manufacturing points

Stainless steel elbows, 1, welding rods should be kept dry during use; calcium-titanium type should be dried at 150℃ for 1 hours, and low-hydrogen type should be dried at 200-250℃ for 1 hours (cannot be repeatedly dried, otherwise the coating is prone to cracking and peeling), preventing the welding rod coating from sticking to oil and other dirt, to avoid increasing the carbon content of the weld and affecting the quality of the welded piece. During elbow welding, repeated heating precipitates carbides, reducing corrosion resistance and mechanical properties. Post-weld hardening is significant, making cracks easy to produce. If welding with similar types of welding rods, preheating above 300℃ and post-weld slow cooling around 700℃ must be performed. If post-weld heat treatment cannot be performed on the welded piece, chromium-nickel stainless steel welding rods should be selected. 2, to improve the corrosion resistance and weldability of stainless steel elbows, appropriate amounts of stabilizing elements such as Ti, Nb, Mo are added, resulting in better weldability. When using similar types of chromium stainless steel welding rods, preheating above 200℃ and post-weld tempering around 800℃ should be performed. If heat treatment cannot be performed on the welded piece, chromium-nickel stainless steel welding rods should be selected.
