LMD 25 hose connector German LMD 25 model LMD 25 price

LMD 25 hose connectors are connection tools between pipes, serving as detachable connection points between components and pipes. Main pipe connectors come in a wide variety of types. Commonly used pipe connectors are generally divided into two categories: rigid pipe connectors and hose connectors. Rigid pipe connectors include flared, compression, and welded types, while hose connectors are primarily crimped rubber hose connectors. A compression pipe connector consists of three parts: the connector body, the ferrule, and the nut. When the ferrule and nut are placed on the steel pipe and inserted into the connector body, tightening the nut causes the outer front end of the ferrule to fit against the conical surface of the connector body, and the inner cutting edge uniformly bites into the seamless steel pipe, forming an effective seal. These are sealed pipe connectors suitable for non-corrosive or corrosive media such as oil, water, and gas. The specifications for use with aluminum-plastic pipes are relatively flexible. After connection to the pipeline, they feature reliable connections and good sealing performance.

LMD 25 hose connector manufacturing process

Tee connector forming involves flattening a pipe blank larger than the tee diameter to approximately the tee diameter size, and opening a hole at the branch pipe stretching location; the pipe blank is heated, placed into a forming die, and a punch for stretching the branch pipe is inserted into the pipe blank; under pressure, the pipe blank is radially compressed, and during radial compression, metal flows toward the branch pipe direction and forms the branch under the stretching action of the punch. The entire process forms the shape through radial compression of the pipe blank and stretching of the branch pipe section. Unlike hydraulic bulging tees, the metal for the branch pipe of a tee connector is compensated by the radial movement of the pipe blank, so it is also called the radial compensation process. Since the tee is pressed after heating, the equipment tonnage required for material forming is reduced. Hot-pressed tees have wider adaptability to materials, suitable for low-carbon steel, alloy steel, and stainless steel; especially for large-diameter tees with thicker walls, this forming process is typically used.

LMD 25 hose connector classification

1, DPJ type, also known as DPJ external thread end-connect metal hose connector, is an end-connect type used to connect metal hoses to enclosures as a straight connector. 2, DKJ connector, DKJ compression-type metal hose connector, is a compression type used to connect metal hoses to steel pipes without threads, allowing connection of unthreaded steel pipes to hoses, eliminating the threading process, requiring only screwing in the screw. 3, DGJ connector, DGJ self-fixing metal hose connector, is a self-fixing hose connector used to connect metal hoses to unthreaded steel pipes or unthreaded equipment outlet openings, eliminating the threading process. 4, 90 degree elbow connector, follows the imperial thread standard, A, C, F parts are made of high-quality steel, D part is made of die-cast iron sheet. The color is silver-white metallic, and the operating temperature ranges from -40 degrees to 100 degrees. 5, Y shaped connector, Y shaped tee metal hose connector, its form is one end connector connecting to thin-wall steel electrical conduit, and the other two ends metal connectors connecting to metal hoses. 6, T shaped connector, T shaped tee metal hose connector, similar to the Y shaped tee metal hose connector, its form is one end connector connecting to thin-wall steel electrical conduit, and the other two ends metal connectors connecting to metal hoses. 7, stainless steel connector, stainless steel hose connectors adopt an end-connect type, cast from standard stainless steel, with a compact structure, high strength, and reliable connection to the hose.

LMD 25 hose connector classification

Classification by pipe diameter: The branch connections of equal-diameter tees are all 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: Hydraulic bulging of tees is a forming process in which the branch pipe is bulged out through axial compensation of the metal material. The process involves using a dedicated 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; the wall thickness of both the main pipe and the shoulder increases. Because 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: Hot pressing of tees involves flattening a pipe blank with a diameter larger than that of the tee to approximately the tee's diameter, cutting 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, 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 called the radial compensation process. Since the tee is pressed after heating, the equipment tonnage required for material forming is reduced. Hot-pressed tees have broad material adaptability and are suitable for low-carbon steel, alloy steel, and stainless steel; this forming process is typically used for large-diameter tees with thicker walls. Classification by material: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon-chromium-nickel alloy, pvc, etc. Classification by manufacturing method: top-made, pressed, forged, cast, etc.
