Chongqing stainless steel processing of stainless steel pipe fittings of different connection methods we use stainless steel pipe fittings, in many cases the need to install special technology, for example, be welded parts, etc., depending on the demand, the method may be connected is different, so as to more conducive to the use of stainless steel pipe fittings. 1, Chongqing steel processing stainless steel pipe fittings from the arc using reflow method, using Tan crater filled crater approach. Should be completed within the slope arcing over said, you can not beat the arc in the pipe and fittings busbar surface and arcing. Find cracks, holes and other phenomena in the arcing process, to promptly handle clean. 2, stainless steel pipe fittings in lifting time should be separated from other metals, to avoid direct contact. Padded wood, non-metallic materials such as rubber sheet isolation approach can be used. 3, stainless steel pipe fittings in continuous welding, the temperature should not exceed 60 degrees Celsius. When tack welding, weld the inside should be filled with argon protection. Cutting the time can not use ordinary grinding wheel cutting, you should use stainless steel pipe fittings dedicated grinding wheel or plasma cutting. 4, stainless steel pipe fittings stainless steel piping and non-pipe when the pipe connections, welded butt joint welding before bottoming in the pipeline and the cavity should be filled with argon, before you can make TIG. In connection weld stainless steel welds at the trash later to weld pickling and passivation. Annealing heat treatment and processing of stainless steel Chongqing Chongqing stainless steel processing annealing heat treatment is intended to soften the organization and organizational restructuring carried out, in order to soften enough to easily carry out machining, control, drawing, molding, etc., can be divided into two ... like annealing Method stainless steel door, i.e. the class of stainless steel heated to above the phase transition temperature sufficiently gradual cooling complete annealing, and heated to a temperature below the phase transition point air cooling or slow cooling of the low-temperature annealing. From the point of view of preventing the deformation, not too fast Greek single heating, appropriate heating rate is generally 150 ~ 2000C / hr, holding time of standard material according to the thickness or diameter for every 25 mm, for an incubation for 1 hour meter . When I Division, when fully annealed stainless steel moldings, the cooling method is best to make the slow cooling stainless steel, the cooling rate is good hopes at 20 ℃ / hr or less, when the low-temperature annealing, the heating temperature from the start of continuous air cooling.
