TECNIFUELLE hose fittings Germany TECNIFUELLE model TECNIFUELLE price

TECNIFUELLE hose fittings are end-type straight connectors used to connect metal hoses to enclosures; they are detachable connection points between components and pipes. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic piping. Hose assemblies are high-quality flexible pipelines in modern industrial piping 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 made of stainless steel wire or steel strip woven 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 give the hose good flexibility and fatigue resistance, allowing it to easily absorb cyclic loads from various motion deformations, especially providing the ability to compensate for large displacements in piping systems.

TECNIFUELLE hose fitting installation

Cut pipes using a sawing machine or specialized pipe cutting equipment; flame cutting or grinding wheel cutting is strictly prohibited. The cut surface must be flat, with a plane flatness no greater than 1 mm and perpendicularity to the pipe axis no greater than 1 degrees. Remove burrs and chips using files or scrapers. Clean debris and floating rust from inside the pipe using clean compressed air or other methods. Use a pipe bender for cold bending; hot bending is not allowed (for large-diameter pipes, right-angle fittings can be used instead of bending). The bending radius must be more than 4 times the pipe diameter. The ovality (change in major/minor axes) at the bend must be less than 10% of the pipe diameter, and no wrinkling is allowed. If there is a fitting at the bent end, a straight section of pipe must connect the end to the fitting to avoid affecting installation. Use tungsten inert gas (TIG) welding for root pass followed by arc welding for filling. When pressure exceeds 21mpa, purge the inside of the pipe with 5l/min argon gas simultaneously. When the pipe wall thickness is greater than 2mm, cut a 35° bevel on the outer circumference and leave a 3mm gap at the joint. When the wall thickness is ≤ 2mm, do not cut a bevel, but leave a 2mm gap at the joint. During alignment, the pipe axes must coincide; misalignment must be less than 15% of the wall thickness, and the deviation rate must be less than 1:200. Pipe clamp backing plates are generally welded directly or via angle iron brackets to structural members; for concrete floors or walls, brackets are fixed with expansion bolts. Ensure pipe clamps are leveled, meaning the mounting surfaces are at the same height. Pipe clamp spacing: for pipe diameters ≤ φ10, approximately 0.5–1 meters; for pipe diameters φ10–25, approximately 1–1.5 meters; for pipe diameters φ25–50, approximately 1.5–2 meters. At right-angle bends, use one pipe clamp on each side. Connect pipe fittings to equipment and pipes to fittings segment by segment until all pre-installation is complete. For pipe fitting installation methods, see Chapter 4. Weld pipe clamp backing plates to structural members or brackets; do not weld pipes to clamps or brackets. After pre-installation and inspection, mark matching numbers on the piping, assign a unique number to each piece, and list them in a table for reference. After dismantling and cleaning, reassemble according to the numbers.

TECNIFUELLE hose fitting selection

How to select three-way water pipe fittings: 1. Check suitability: The selection of three-way fittings depends first on the actual conditions of the water pipes. Three-way fittings come in different shapes and specifications, mainly divided into T-shape or Y-shape, with equal-diameter and reducing nozzles. Equal-diameter nozzles have three holes of the same diameter; reducers are generally larger than the branch pipes but smaller than the main pipe. Choose according to your actual needs and select accessories compatible with the pipes, preferably from the same brand. 2. Check material: Materials for water pipe three-way fittings mainly include carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon-cast, pvc, etc. Different materials have different prices and applicability; users can choose based on their own situations. Regardless of the material, check for compliance first. Smell for pungent odors, and for careful purchasing, check for product certification marks. 3. Check appearance: When buying three-way fittings, observe the appearance for gloss, uniform wall thickness, and clean, tidy pipe walls. Do not choose substandard "accessory" grade fittings. For threaded three-way fittings, also check if the thread pitch and spacing are evenly distributed. 4. Check performance: Performance is the direct standard for product use; poor performance affects service life. You can soak the three-way fitting in hot water. If the water pipe loses its original hardness, its performance is not good.

TECNIFUELLE hose fitting common issues

1. Remove residue: When installing water pipe connectors, completely remove various residues from the pipeline to prevent valve core damage, blockage, clogging, and leakage. Also, clean the surface to prevent residual construction materials. 2. Do not use excessive force during switching: For any household accessory, do not apply excessive force when switching; simply shake or rotate. Even traditional home fixtures do not require excessive effort to tighten. In particular, do not use handles as railings for support. After a period of use, disassemble and clean products with outlet filter covers to remove residue. Products with plastic hoses should remain naturally extended to avoid rupture. 3. Keep household three-way fittings extendable: The shower metal bellows of household hose fittings should remain in a naturally extended state. Do not coil it around the faucet when not in use. Also, whether in use or not, ensure no dead angles form at the connection between the plastic hose and the valve body to prevent hose rupture or damage. 4. Pay attention to regular cleaning: Domestic water pipe connectors that are not used for long periods may lead to incomplete closure, leakage, loose handles, loose connections, and dripping. Customers can often handle these issues themselves.
