zimmer Sommer hose fittings German zimmer Sommer models zimmer Sommer prices

zimmer Sommer hose fittings are high-quality flexible pipes in modern industrial piping systems. They mainly consist of bellows, braided mesh, and fittings. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape. The outer braided mesh 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 processing of ultra-thin-walled seamless or welded stainless steel pipes. Since the elastic characteristics of the bellows profile determine that the hose has good flexibility and fatigue resistance, it can easily absorb cyclic loads from various motion deformations, especially having the ability to compensate for large displacements in piping systems.

zimmer Sommer hose fitting classification

Pipe fittings come in many varieties. Commonly used pipe fittings can generally be divided into hard pipe fittings and hose fittings. If classified by the connection method between the fitting and the pipe, hard pipe fittings include flare type, compression type, and welded type, while hose fittings are mainly crimped rubber hose fittings. Pipe fittings are components used in hydraulic systems to connect pipelines or install pipelines onto hydraulic elements; this is a general term for connectors that can be assembled and disassembled in fluid paths. Types of pipe fittings include: end straight-through fittings, straight-through fittings, tee fittings, elbows, fittings with live nuts, hinged fittings, plugs, transition fittings, double compression fittings, etc.

zimmer Sommer hose fitting installation

Installation is the most critical step, directly affecting sealing reliability. Specialized pre-assembly tools are generally required. Fittings with small pipe diameters can be pre-assembled on a vise. The specific method involves using a fitting body as the base, pressing the nut and ferrule onto the pipe. Main types include compression straight-through pipe fittings, compression end straight-through pipe fittings, and compression tee pipe fittings. The depth of the conical hole on these fitting bodies often varies, which can result in loose spherical contact between the ferrule and the inner conical surface of the fitting body when a pipe pre-assembled for a straight-through fitting is used for a tee fitting connection, causing leakage. This issue is often overlooked. The correct approach is to use the same type of fitting body for pre-assembly on the corresponding connection end as used on one end of the pipe, maximizing the avoidance of leakage. Maintain coaxiality between the pipe and the fitting body as much as possible; excessive pipe deviation will also cause sealing failure. Pre-assembly force should not be too high. The inner cutting edge of the ferrule should just embed into the outer wall of the pipe, and the ferrule should not show obvious deformation. If the ferrule deforms severely during pre-assembly, it will lose its sealing function.

zimmer Sommer hose fitting crimping

How to crimp high-pressure pipe fittings: first, the international metric internal thread flat-face fitting; second, the international metric compression fitting; third, the international metric internal thread 74 degree internal cone face fitting; fourth, the international metric internal thread spherical face fitting; fifth, mining hydraulic support fittings. There are some points to note when using high-pressure oil hose fittings: 1, when handling high-pressure oil hoses, care must be taken to avoid friction on the outer surface to prevent damage. Although the rubber hose is intended for use, we must not allow leaks to appear on the outer surface of the high-pressure oil hose. 2, do not bend the high-pressure oil hose, as this will cause internal damage, adding unnecessary trouble for future use. 3, do not put the high-pressure oil hose into immediate use; it is recommended to filter it with water or similar fluids first. Some high-pressure oil hoses are acid and alkali resistant; we cannot use liquids that conflict with the current fluid for testing. 4, when installing high-pressure oil hose fittings, they must be tightened to prevent fluid leakage.
