EM-TECHNIK hose connectors Germany EM-TECHNIK model EM-TECHNIK price

EM-TECHNIK hose connectors are components used to connect water pipes. Connectors can be classified by usage method into: external thread end-connecting water pipe connectors, ferrule-type water pipe connectors, and self-locking water pipe connectors. External thread end-connecting water pipe connectors are die-cast from zinc alloy material, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure, no pores, and high strength. Ferrule-type water pipe connectors can connect threaded-less steel pipes to hoses, eliminating the threading process; simply screw in the fastener. They feature a compact structure and high strength. Water pipe connectors can connect threaded-less steel pipes or threaded-less equipment cable outlets to hoses, eliminating the threading process; they are die-cast from zinc alloy material, 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.

EM-TECHNIK hose connector cleaning

To ensure the cleanliness of the lubrication system and supply clean grease to mechanical equipment bearings, pre-installed piping must be dismantled and cleaned. Cleaning methods include kerosene cleaning and pickling. 1. Kerosene cleaning objects and methods: (1) Copper pipes, stainless steel pipes; (2) Steel pipes that have undergone pickling treatment before pre-installation, with no rust or iron oxide scale on the inner wall; (3) Pipe joints contaminated during pre-assembly; (4) Dismantle the pipes and joints requiring cleaning. Wipe the inside of the pipes clean with a cloth (lint-free yarn) soaked in kerosene. Soak both ends and joints in kerosene for cleaning. Then apply machine oil or fill with grease inside the pipes, and seal both ends tightly for installation; (5) No visually visible contaminants (such as iron filings, fibrous impurities, welding slag, etc.) should remain after cleaning. Special attention must be paid to thoroughly cleaning the welding slag on the inner wall at weld seams. 2. Pickling objects: (1) Steel pipes not pickled before pre-installation; (2) Steel pipes that, although pickled, suffer from severe corrosion. 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) Rust removal: Remove rust spots, rolling iron chips, etc., from the pipe wall using pickling solution; (4) Water washing and high-pressure water rinsing: Rinse off attachments generated during the above operations with clean water, and flush the inside of the pipes with high-pressure water; (5) Neutralization: Neutralize 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 until the pipe material is completely dry; (7) Rust prevention; (8) Inspection: Inspect the pickled pipe material to verify cleanliness; (9) Packaging and storage: Immediately after pickling, seal the pipe openings with plastic or plastic tape to prevent intrusion of foreign matter, moisture, etc. 4. Precautions for pickling: (1) All welding operations on the pipes must be completed before pickling; (2) During dismantling, transportation, and pickling, take care not to damage the piping, threads, and sealing surfaces. Seal openings with tape or plastic tubes; (3) Before pickling, thoroughly remove welding slag, spatter, and clear varnish from the pipes generated during welding; (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 rust removal in acid solution to prevent acid erosion; (5) During pickling, ensure that matching marks on the pipes do not disappear or become blurred.

EM-TECHNIK hose connector material classification

High-pressure tees. There are two common types of high-pressure tees: welded high-pressure tees and integrally forged high-pressure tees. Welded high-pressure tees are made from high-quality high-pressure steel pipes. The manufacturing method is similar to branch connection by cutting an opening; the hole opened on the main pipe must match the diameter of the connected branch pipe. Strict welding quality requirements apply; typically, preheating is required before welding, and heat treatment is performed after welding. Their specifications and pressure ranges are the same as high-pressure elbows. Integrally forged high-pressure tees generally use threaded flange connections. Their specification range is DN12~DN109mm. Service temperature: 25# carbon steel high-pressure tees are for use below 200℃, low-alloy and stainless acid-resistant steel high-pressure tees are for use below 510℃. Service pressure is below 20.?0MPa. Common welded tee pipes include 3 types: elbow type, right-angle type, and flat-weld opening type. 1) Same-diameter elbow welded tee: Commonly known as pants-shaped pipe, it is made by cutting half the circumference of the outer arm from two 90° elbow pipes, then butt-welding the remaining two elbow sections to form a same-diameter tee. 2) Right-angle tee fabrication: Available in same-diameter and reduced-diameter types. During fabrication, development drawings are drawn based on two intersecting cylindrical surfaces. Oxy-acetylene flame cutting tools are generally used for cutting, followed by welding. 3) Flat-weld opening tee: The tee weld seam is short, deformation is minimal, pipe material is saved, and processing is simple. The fabrication method involves cutting an elliptical hole in a straight pipe. The minor axis of the ellipse equals 2/3 of the branch pipe's outer diameter, and the major axis equals the branch pipe's outer diameter. Then, heat the pipe walls on both sides of the elliptical hole to approximately 900℃, and flare them outward to form a round opening.

EM-TECHNIK hose connector classification

Hose connector types include: one-piece hose connectors, crimped hose connectors, internal-lock hose connectors, reusable hose connectors, etc. One-piece hose connectors are a type of high-quality flexible piping in modern industrial pipeline systems, mainly composed of bellows, wire braid, and fittings. Hose connectors are mainly applied in gas distribution systems and gas pressure regulating stations. Their function is to electrically insulate and isolate sections of gas distribution pipelines and between gas pressure regulating stations and distribution pipelines, protecting them from electrochemical corrosion and extending service life.
