Metric sizes from 4 to 42mm made of carbon steel or stainless steel are most prevalent. Assembly of the system may be repeated without damage to the parts involved. Indicated pressures are for steel tubes only. The plating should also be hard enough to resist abrasive wear and provide good high-temperature stability. Then tighten the nut with a wrench until the cutting edge of the ring is in contact with the tube and prevents rotation of this. Tighten the union nut with screw wrench approx. If this is not available, hardened blocks must be used for manual pre-assembly.
It also allows the pipe exit direction to be adjusted relative to the fitting, allowing the bolt to be tightened independently. Zinc-nickel plated fittings should not exhibit any traces of white or red rust even after 1,000 hours of exposure to salt spray testing. This check is peremptory for the safety of all concerned! Adjustable standpipe fittings facilitate the connection of a metric tube with a 24° conical bore. About 50% of our products are mainly exported to Germany, Japan, France and other countries. Remove any internal and external burrs. At any time, you can exercise your rights by sending information to the Administrator. The larger diameter of the cutting ring must face the nut.
Metal sealing surfaces will typically allow some leakage. The assembly of B3 and B4 rings must be done with the same procedures and tools. A shuttle valve known in Europe as an alternating valve is T-shaped and allows flow to pass from one of two inlets to an outlet port. They are used primarily in medium- to high-pressure applications—up to 800 bar 11,600 psi. The fitting should neither be used to correct a wrong alignment nor to be a support for the tube.
Further inspections are necessary during the pre-assembly every 30-50 tightenings. All values expressed in Kilograms Kg for the linear push on the pre-assembly machine, represent the right strength necessary to have the correct incision of the pre-assembly lifting the required 70% of the front of the edge of the cutting ring. Pressure Rate Reduction The allowed working pressure for stainless steel fittings manufactured with 1. These may vary according to the materials and of the tolerances of the employed components. Operating temperature is between -20°C and +100°C.
The B3 ring helps fast assembly of removable tubes, avoids welding, tapping and flaring, thus assuring maximum simplicity for complex oleo-dynamic systems. Seal on Threaded Ends To obtain the maximum performance, the taper male thread is to be matched with the tapered female thread. The second groove invisible balances the forces on the whole ring, prevents vibrations from reaching the first groove and stops the stapling of the tube at a predetermined value. Material is carbon steel, forged body. The check valve shown here has an arrow to indicate direction of flow. Remember to oil the thread, nut and ring. With this new ring, double clinching of the steel tube is still possible and also, for obvious reasons of safety, visual inspection of correct coupling between the ring and the steel tube, also maintaining the current, perfectly functional system of assembly of the system of assembly that is now widely known to product users.
The first of which is visible due to lifting of an outer edge on the diameter of the tube, allows the water tightness and anti-unthreading of the ring. During tightening by the nut, the ring deforms according to the bore of the 24° cone of the fitting and bites into the steel tube, producing two deep cuts, the first of which is visible due to the lifting of an outer edge on the diameter of the tube, ensuring water tightness and antiunthreading of the ring. Because fluid can flow in only one direction, the outer body usually has an arrow pointing in the direction of flow to aid proper installation. Assembly or pre-assembly operationsdirectly on the fitting are not allowed. For example, Brennan offers a proprietary zinc-nickel plating that far exceeds U.
No O-rings or other elastomeric components are needed to provide a seal. In this case, make sure that the bench and vice in which the block is clamped are firmly fastened to prevent any possibility of movement caused by the twisting moment applied to the nut during the pre-assembly phase. An internal floating ball blocks flow from one inlet port or the other. The data will be processed until the opposition to processing or withdrawal of consent is expressed. John Joyce is director of marketing, Brennan Industries, Cleveland. W ithout the reinforcement it is not possible to operate with the above mentioned materials. This ensures interchangeability among leading brands of fittings.
Typical end connections are 24-deg flareless shuttle valve tube style. Extremely long tubes or tubes undergoing high stress have absolutely to be fixed by using some support to avoid excessive vibrations that could cause damage to the system. B3 Technical Characteristics The Cast fitting assures a perfect seal, independently from the fluid used, provided that no corrosive fluids be employed and the nominal pressures be not trespassed. Standpipe fittings are usually specified for harsh environments, such as high-temperature and aggressive fluids which might destroy soft seals. Carbon-steel fittings may cost less initially, but the long service life of stainless steel provides a significant reduction in total cost of ownership, leading to fewer parts replacement and lower maintenance costs. Finish Treatment Inox All the fittings are treated with steel spheres which eliminate all oxides and burrs due to the machining phase, without altering or damaging the product.
We believe that you should be doing what you love to do. In the case of thin-walled or soft pipes a reinforcing ring must be used. The coupling and uncoupling is done almost without oil leaks. Capable to Produce a 5 Million Pieces per Month With the support of 110 skillful workers, our three factories covering an area of 10,000 square meters in total can reach an output of 5 million pieces per month. The plating thickness is 8 ÷ 12 microns and resistance in saline fog with standard salt concentration is 96 hours before the protective layer begins to wear off. Tighten the nut by hand until the cutting ring rest firmly on the nut. Connection couplings Male couplings Bulkhead couplings Welding couplings Straight male connections 24°-cone sealing or shaft Adjustable connections with 24°-cone sealing or shaft Reduction couplings Female stud couplings Banjo couplings Adjustable W.
The fitting must be replaced at each tightening. The cutting ring, after heat treatment to harden the surface, passivation treatment and ecological zinc-plating, follows a bath which facilitates the assembly. During tightening by the nut, the ring deforms according to the bore of the 24° cone of the fitting and bites into the steel tube, producing two deep cuts, one of which is visible due to the lifting of an outer edge on the diameter of the tube. The sealing of the two components is between the 24-deg seat in the male end and the corresponding female end. The processing of your personal data in the form of an e-mail address is based on Art.
