NITO hose connector Germany NITO model NITO price

NITO hose connectors are end-fittings, used as straight connectors to attach metal hoses to enclosures; they are detachable connection points between components and pipelines. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic piping. Hose connectors are a type of high-quality flexible piping in modern industrial pipeline systems. They mainly consist of bellows, a wire braid, and fittings. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape, and the outer braid of the bellows is woven from stainless steel wire or steel strip according to specific parameters. The fittings or flanges at both ends of the hose match the fittings or flanges of the customer's pipeline. The bellows of the hose are formed by high-precision plastic working of extremely thin-walled seamless or welded stainless steel pipes. The elastic characteristics of the bellows profile determine that the hose has good flexibility and fatigue resistance, making it easy to absorb cyclic loads from various motion deformations, especially the ability to compensate for large displacements in pipeline systems. Media visualization (media visibility), process automation.

NITO hose connector types

1, classified by pipe fitting diameter, generally includes equal-diameter tees and reducing tees. 2, classified by branch direction, includes straight tees and lateral tees. 3, classified by material, includes carbon steel, alloy steel, stainless steel, copper, pvc tees, etc. 4, classified by connection method, includes standard tees, threaded tees, compression tees, and socket tees. 5, tee designation methods are as follows: for equal-diameter tees, such as "T6" tee, it indicates an equal-diameter tee with an outer diameter of 6 inches. 6, for reducing tees, for example, "T4×4×3.5" indicates a reducing tee with a same diameter of four inches and a reduced diameter of 3.5 inches. The pressure rating is the same as that of elbows, and the specification range is also the same.

NITO hose connector manufacturing process

Tee joint forming involves flattening a pipe blank larger than the tee diameter to approximately the tee diameter size, and opening a hole at the branch location; the pipe blank is heated, placed into a forming die, and a stretching punch for the branch is inserted inside the pipe blank; under pressure, the pipe blank is radially compressed, and 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 shape through radial compression of the pipe blank and stretching of the branch section. Unlike hydraulic bulging tees, the metal for the branch of a tee joint is compensated by the radial movement of the pipe blank, so it is also called the radial compensation process. Since hot pressing is used to form the tee, 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 materials; especially for large-diameter tees with thicker walls, this forming process is typically used.
