WIDOS hose connector Germany WIDOS model WIDOS price

WIDOS hose connectors are end-type straight fittings used to connect metal hoses to enclosures; they are detachable connection points between components and pipelines. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic piping. Hose connectors are high-quality flexible pipes in modern industrial piping systems. They mainly consist of bellows, a wire braid, and connectors. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape, and the outer braid of the bellows is woven from stainless steel wire or steel strip according to specific parameters. The connectors or flanges at both ends of the hose match the connectors 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.

WIDOS hose connector material classification

High-pressure tee. There are two common types of high-pressure tees: welded high-pressure tees and integrally forged high-pressure tees. Welded high-pressure tees use high-quality high-pressure steel pipes as material, with a manufacturing method similar to branch connection by cutting an opening; the hole opened on the main pipe must match the diameter of the connected branch pipe. Welding quality requirements are strict, usually requiring preheating before welding and heat treatment after welding, with specifications and pressure ranges similar to high-pressure elbows. Integrally forged high-pressure tees generally use threaded flange connections. Their specification range is DN12~DN109mm, operating temperature for 25# carbon steel high-pressure tees is below 200℃, for low-alloy and stainless acid-resistant steel high-pressure tees is below 510℃, and operating pressure is below 20.?0MPa. There are 3 types of commonly used welded tee pipes: elbow type, right-angle type, and flat weld mouth type. 1) Same-diameter elbow welded tee: commonly known as pants tee, it is made by cutting off half the circumference of the outer arm of two 90° elbows, then butt-welding the remaining two elbows together to form a same-diameter tee. 2) Right-angle tee fabrication: available in same-diameter and reducing types; during fabrication, development drawings are drawn based on two intersecting cylindrical surfaces, generally cut using an oxy-acetylene flame cutter, and finally welded. 3) Flat weld mouth tee: the tee weld seam is short, deformation is small, saving pipe material and simplifying processing. The fabrication method involves cutting an elliptical hole on a straight pipe, where 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 heating the pipe walls on both sides of the elliptical hole to around 900℃ and flanging them outward to form a round mouth.

WIDOS hose connector precautions

Before installation, all steel pipes can be pickled according to the requirements of Chapter 9, especially steel pipes connected with compression fitting connectors should be pickled first, and then the compression ring is pre-tightened on the pipe end; (2) All pipe connectors should be cleaned with kerosene before installation, and the o type O-rings inside should be temporarily removed and stored, to be placed back during formal installation; (3) During construction, keep the oil ports of pumps, distributors, and other equipment, as well as the openings of pipe connectors and pipe ends, clean, preventing water, dust, and other foreign matter from entering; (4) Pipelines should be laid in a free state, and excessive radial force should not be applied to forcibly fix and connect pipelines after welding; (5) Check the oil holes of bearing housings in advance to ensure internal oil passages are unobstructed and that the oil port threads match the connectors.

WIDOS hose connector classification

Different names for the same type of pipe connector are easy to remember: internal connectors have external threads; external connectors have internal threads. Threaded connectors are generally used for pipelines to provide connection. External thread: refers to threads on the outside of pipelines, etc., which can generally be touched directly. Internal thread: refers to threads on the inside of pipelines, etc., which generally require reaching inside to touch. In industry, you may also encounter right-hand and left-hand threads. Right-hand thread: threads that tighten in the clockwise direction (righty-tighty), commonly encountered in daily life, with screws being the most common example. Left-hand thread: threads that must be tightened in the reverse direction, less common in daily life but frequently seen in specialized fields such as ventilation.
