TRANSAIR hose fittings Germany TRANSAIR model TRANSAIR price

TRANSAIR hose fittings consist of a nut, metal ring, sealing ring, and the body. They offer waterproofing, dirt resistance, explosion-proof protection, and corrosion resistance, becoming an essential part of industrial piping. Overall, each pipeline has different requirements for metal hoses; plastic-coated metal hose tee joints and suitable bimetallic composite pipes are used for different materials and construction environments.

TRANSAIR hose fitting precautions

Avoid impact and dropping during handling and storage to prevent damage to interfaces and internal components. When installed on high-temperature fans, ensure concentric alignment to guarantee proper operation of the rotary joint. Connections between compression fittings and pipelines must use flexible hoses; rigid connections are strictly prohibited. The inlet and outlet of compression fittings should connect directly to flexible hoses to reduce auxiliary weight on the fitting and extend service life. For the assembly of the inner tube of the compression fitting, pay attention to dimensional fit and auxiliary support for weight. For the fit between the inner tube of the internal-rotation rotary joint and the joint, a tolerance fit of H8/e7 is recommended. Support and anti-rotation for the compression fitting should be appropriate; generally, the rod diameter should be 2mm smaller than the anti-rotation hole to avoid affecting the free adjustment and compensation of the rotary joint. The perpendicularity of the pipe end face to the axis should be less than 0.50. Remove burrs from the end face and chamfer 0.2×450. Apply an appropriate amount of grease to the threaded part and the contact cone surface. Install the compression fitting and nut, paying attention to direction. Hold the pipe fitting and press the end face against the shoulder of the joint body. Mark the compression fitting and tighten the nut. Ensure the pipe fitting does not rotate, tightening by 1.3~1.5 turns. Remove the nut and check the bite condition of the ferrule.

TRANSAIR hose fitting selection

A tee joint, as the name suggests, is a pipe fitting with 3 openings. This hardware can transport and separate gases and liquids, and its applications are widespread, such as for repairing water pipes without shutting off the water supply and in metal hose pipeline systems. 1. Check suitability: The selection of tee fittings depends first on the actual conditions of the water pipe. The shapes and specifications of three-way fittings vary. They are mainly divided into T shape or Y shape, with equal-diameter and different-diameter nozzles. Equal-diameter nozzles have three holes of the same diameter; the gearbox is generally larger than the main pipe, and 2 pipes are smaller than the main pipe. You can choose according to your actual needs and select accessories compatible with the pipeline, preferably from the same brand. 2. Check material: Materials for water pipe tee joints mainly include carbon steel, cast steel, carbon structural steel, stainless steel, copper, aluminum profiles, plastic, argon arc casting, pvc, etc. Different materials have different prices and applicability; everyone can choose based on their own situation. Buy now, but regardless of the material, first check if it is qualified. Smell for any unpleasant odors, and if purchasing carefully, check for product qualification marks. 3. Check appearance: When purchasing tee fittings, pay attention to their appearance, checking for smoothness, uniform pipe wall thickness, and clean walls. Do not choose "accessory" grade pipes. If it is a threaded tee joint, also pay attention to whether the external thread development and pitch are uniformly distributed. 4. Check performance: Performance is the direct standard for product adoption; too low performance will affect service life. You can soak the tee joint in boiling water. If you find the water pipe lacks initial strength, then its performance is not very good.

TRANSAIR hose fitting structure

When disconnected (both ends closed): When the sleeve of the female body is moved to the other end, the stainless steel balls automatically roll outward. The male body disconnects under the combined spring force of the valves in the female and male bodies. The valves in the male and female bodies close separately, instantly blocking fluid flow. When connected: When the male body is inserted into the female body, the sleeve returns to its original position under the action of the spring, and the steel balls roll to lock the male body tightly. At the same time, the valves in the female and male bodies push against each other to open, allowing fluid flow. The O O-ring completely prevents fluid leakage. When disconnected (both ends open): When the sleeve of the female body is pushed to the other end, the steel balls automatically roll outward, so the male body is removed. Since neither the male nor the female body has valves, fluid flows outward. When connected: When the male body is inserted into the female body, the sleeve is pushed by its spring force to the previous position, causing the steel balls to lock. Fluid flows, and the O O-ring prevents liquid leakage.
