Detailed
The tube clearance step is located in the middle and both ends of the connector, as shown in the figure.When used with the stainless steel joint, it can ensure both ends of the concentricity, but also to ensure the determination of capillary size.There should be sufficient area in the step area to withstand the sleeve load due to the different concentricity of the mounting conduit.When designing a sleeve with partial steps, its overall length should be the length of the capillary section of brazing and the total length of each step.The dimensions of the slotted sleeve of the standard copper joint are listed in the table.
The other two different sleeve connectors, shown here, both use pre-installed brazing alloys and alloy retention grooves. The structure shown in the standard plastic joint drawing is generally limited to light conduits and can be manufactured with corrugated brazing alloy grooves.The structure shown in the figure is a machined joint that USES an exothermic cartridge to provide brazing heat.The main advantage of this connection is that it is possible to make a suitable connection using only the reactants and a 6V battery in remote control or limited space.In the brazing of exothermic cartridge, the thermal reaction time is short and the joint heats up quickly, so the workpiece can undergo high temperature for a short time, which can reduce the adverse impact on the heat treatment of the catheter material and the grain size.These connections with a diameter of 1 1/2in are currently commercially available.
