LU-EN hose connector Germany LU-EN model LU-EN price

LU-EN hose connectors are components used to connect water pipes. Connectors can be classified by usage method into: external thread end-connecting water pipe connectors, compression-type water pipe connectors, and self-locking water pipe connectors. External thread end-connecting water pipe connectors are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure, no porosity, and high strength. Compression-type water pipe connectors can connect unthreaded steel pipes to hoses, eliminating the threading process; simply screw in the fastener. They have a compact structure and high strength. Water pipe connectors can connect unthreaded steel pipes or unthreaded equipment cable outlets to hoses, eliminating the threading process; they are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure and high strength. Widely used in high-end buildings, hotels, hospitals, office towers, stadiums, museums, government agencies, villas, and residential communities.

LU-EN hose connector functions

It connects the braided sleeve to the entire corrugated pipe. Meanwhile, the connector is also a component that connects metal hoses to other piping accessories and equipment. It ensures the medium operates normally within the piping system. The connector material is usually the same as that of the corrugated pipe and braided sleeve, and most are stainless steel. For transporting non-corrosive media, some larger-diameter metal hoses can be made of carbon steel. Metal hose connectors for corrosive media (if designed accordingly) take appropriate measures to avoid contact with the medium and can also be made of carbon steel. Connector structures are roughly divided into three categories: screw type, flange type, and quick-connect type. Under high-pressure working conditions, connectors for metal hoses (explosion-proof hoses) with a thread diameter less than 50 mm are mostly threaded. After tightening the threads, the inner and outer conical surfaces of the two connectors fit tightly to achieve sealing. The cone angle is typically 60 degrees, while 74 degrees is also effective. This structure offers good sealing performance, but concentricity of the two mating parts must be ensured during installation. To address issues of repeated disassembly, assembly, and concentricity often encountered in actual projects, the connector can also be designed to match a conical surface with a spherical head.

LU-EN hose connector advantages

High strength: Based on the principle of cold work hardening of steel, the strength of straight threads rolled onto rebar is significantly improved, making the tensile strength of straight thread connectors higher than that of the base rebar material. Stable performance: The connection process is not affected by worker skill levels, ensuring stable performance. Fast connection speed: Since off-site prefabrication and on-site assembly are used, rebar with prefabricated threads can be mass-produced and stored at the rebar yard. When schedules are tight, only additional assembly workers are needed at the construction site. Easy management: Mismatches between sleeves and rebar do not occur, and inspection is convenient. Simple operation: Ordinary workers can become proficient after a few hours of training. Significant economic and social benefits: Shortens construction cycles, improves engineering quality, reduces energy consumption, benefits environmental protection, reduces equipment investment, and has low additional costs, offering clear economic and social benefits.

LU-EN hose connector crimping

How to crimp high-pressure pipe connectors: First, the international metric internal thread flat-face connector; second, the international metric compression-type connector; third, the international metric internal thread 74 degree internal conical surface connector; fourth, the international metric internal thread spherical face connector; fifth, the mining hydraulic support connector. There are some points to note when using high-pressure oil pipe connectors: 1. When handling high-pressure oil pipes, care must be taken to avoid surface friction to prevent damage. Although the hose is intended for use, we must not allow leaks to appear on the exterior of the high-pressure oil pipe. 2. Do not bend the high-pressure oil pipe, as this can cause internal damage, creating unnecessary trouble for future use. 3. Do not put the high-pressure oil pipe into immediate use; it is recommended to filter it with water or similar fluids first. Some high-pressure oil pipes are acid and alkali resistant; we must not use test fluids that conflict with the current liquid. 4. When installing high-pressure oil pipe connectors, ensure they are tightened to prevent fluid leaks.
