STUCCHI hose fittings Germany STUCCHI model STUCCHI price

STUCCHI hose fittings are straight-through connectors used for linear connections such as instruments. Connection methods include socket welding or threaded connection. They are mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or for final adjustment of pipelines using threaded fittings. Relevant products are all listed in Kuaiyiyou. The structural form should preferably adopt a metal-to-metal contact sealing structure. Gasket sealing structures are generally used in general pipelines transporting water, oil, air, etc., and are made of malleable cast iron. In addition, application requirements and quotation are also factors to consider when selecting. There are numerous types of straight-through hose fittings. Commonly used straight-through hose fittings can generally be divided into two types: hard hose straight-through fittings and soft hose straight-through fittings. If classified according to the connection method between the straight-through hose fitting and the pipeline, hard hose straight-through fittings include flared type, ferrule type, and welded type, while soft hose straight-through fittings are mainly crimped rubber hose straight-through fittings. The connection methods for pipelines and straight-through hose fittings in hydraulic systems also differ; the pipe insertion end uses connecting threads. Tapered threads rely on their conical body to tighten and use materials such as polytetrafluoroethylene for sealing operations, and are mainly used in medium and low-pressure hydraulic systems.

STUCCHI hose fitting cleaning

To ensure the cleanliness of the lubrication system and provide clean grease for the bearings of mechanical equipment, the pre-installed piping must be dismantled and cleaned. Cleaning methods include kerosene cleaning and pickling. 1. Kerosene cleaning objects and methods: (1) Copper pipes and stainless steel pipes; (2) Steel pipes that have been pickled before pre-installation and have no rust or iron oxide scale on the inner wall; (3) Pipe fittings contaminated during pre-assembly; (4) Dismantle the pipes and fittings that need to be cleaned. Wipe the inside of the pipes clean with a cloth (lint-free yarn) dipped in kerosene. Soak both ends and the fittings in kerosene for cleaning. Then coat the inside of the pipes with machine oil or fill them with grease, and seal both ends tightly for installation; (5) There must be no visually visible contaminants (such as iron filings, fibrous impurities, welding slag, etc.) after cleaning. Special attention must be paid to thoroughly cleaning the welding slag on the inner wall of the welds. 2. Pickling objects: (1) Steel pipes that have not been pickled before pre-installation; (2) Steel pipes that have been pickled but are severely corroded. 3. Pickling construction sequence and treatment purposes: (1) Degreasing: Use degreasing agents to remove grease adhering to the piping; (2) Water washing: Use clean water to remove dirt from the pipe material; (3) Derusting: Remove rust spots, rolling iron chips, etc. from the pipe wall in the pickling solution; (4) Water washing and high-pressure water rinsing: Rinse off the attachments generated in the above operations with clean water, and rinse the inside of the pipes with high-pressure water; (5) Neutralization: Neutralize the residual acid liquid on the pipe material with alkaline solution; (6) Drying: To effectively dry, immerse the pipe material in hot water or perform steam drying to ensure the pipe material is completely dry; (7) Rust prevention; (8) Inspection: Inspect the pickled pipe material to check if it is cleaned thoroughly; (9) Packaging and storage: Immediately after pickling, seal the open ends of the pipes with plastic or plastic tape to prevent the intrusion of foreign matter, moisture, etc. 4. Precautions for pickling: (1) Welding operations on the pipes must be fully completed before pickling; (2) During dismantling, transportation, and pickling, take care not to damage the pipelines, threads, and sealing surfaces. Seal the openings with tape or plastic pipes; (3) Before pickling, thoroughly remove welding slag, splashes from welding, and clear lacquer on the pipes; (4) Protect all threaded parts with acid-resistant materials such as plastic tape or rubber tape, or apply dry oil to the threads after degreasing and water washing before derusting in the acid solution to prevent acid erosion; (5) During pickling, take care not to make the matching marks on the pipes disappear or become blurred.

STUCCHI hose fitting applications

A bushing is a component widely used in domestic large-scale power plant supporting projects, seawater, steam, cold water, hot water, oxygen, drinking water, refrigeration, oil, gas, medical gas, sewage treatment projects, municipal engineering, chemical industry, oil refining, metallurgy, fertilizer, papermaking, pharmaceuticals, and other industries. Bushings are used when water pipes need to change diameter. For example, a DN15 water pipe needs to be reduced to a DN20 water pipe. The DN15 water pipe is an external thread pipe, connected to the internal thread end of the bushing. The DN20 water pipe is an internal thread pipe, connected to the external thread end of the bushing. If the DN20 water pipe is an external thread pipe, an internal thread reducer can be connected between the DN20 external thread pipe and the bushing. Threaded connections can be conveniently connected to any water appliances and valve meters. In industrial and domestic applications, they are often used to connect internal and external threads of pipes to change the pipe diameter.

STUCCHI hose fitting precautions

Precautions for using water pipe tees: 1. Clean impurities. When installing water pipe fittings, thoroughly remove all impurities from the pipes to prevent damage to the valve core, clogging, and leakage. Also, clean the surface to avoid residual construction materials. 2. Do not apply excessive force when switching. For any household fixture, do not use excessive force when switching; simply twist or toggle. Even traditional home fixtures do not require much effort to tighten. In particular, do not use the handle as a support or handrail. After a period of use, disassemble and rinse products with outlet filter covers to remove impurities. Products with hoses should be kept in a naturally extended state to prevent breakage. 3. Keep household plumbing fittings flexible. The metal hose of the shower head for household hose connections 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 no dead angles are formed at the connection between the hose and the valve body to prevent hose breakage or damage. 4. Pay attention to regular cleaning. Domestic water pipe fittings that are not used for long periods may result in incomplete closure, water leakage, loose handles, loose joints, and water leakage, which consumers can usually resolve on their own.
