What factors affect the polishing of stainless steel elbow a steel hot pressing or forging process to form the elbow for stainless steel elbow, stainless steel elbow through the elbow and steel pipe butt welding, two workpieces by resistance heating along the entire end face welded together, resistance butt welding and flash butt welding usually have two methods, high productivity, easy to achieve automation, so it is widely used.

Stainless steel elbow not only saves space and reduces weight, but also ensures that the joint will not leak, good sealing performance, stainless steel elbow also has corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and wear resistance, usually used in power stations, chemical industry, petroleum and other industries, stainless steel stamping elbow poor weldability, attention should be paid to the welding process, the premise of heat treatment and the selection of suitable electrodes. Performance?

Stainless steel elbow is widely used, universal is made of ordinary carbon structural steel, low alloy structural steel or alloy structural steel rolled stainless steel elbow, it has a large yield, mainly used as a pipeline or structural parts for conveying fluids, the use of ball valves with stainless steel elbow, globe valves and gate valves, not allowed for flow regulation, only fully open or fully closed to avoid corrosion and accelerated wear of the sealing surface, gate valves and threaded globe valves inside With reverse sealing device, handwheel rotated to the upper position and tightened to prevent media leakage from the packing.

Factors affecting the polishing performance of stainless steel elbow, raw material surface defects (scratches, pockmarks, pickling), after deep punching, the surface of the large deformation area will appear small black spots, affecting the performance of BQ, the material of raw materials, the hardness is too low, not easy to polish, the hardness is too low, the surface is easy to appear orange peel when drawing deep, affecting the performance of BQ, high hardness BQ is better.

Most stainless steel elbow fittings for welding, in order to improve the quality of welding, a certain angle and edge groove at both ends, this requirement is also very strict, the side of the thickness, angle, deviation range are specified, geometric dimensions than pipe fittings, elbow surface quality and mechanical properties and pipe basically the same, in order to facilitate welding, the steel to be connected to the pipe should be the same, stainless steel elbow in addition to a few hydrogenated Can resist the erosion of various chemical media, with excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no breeding bacteria, no electrochemical corrosion.

Long-term storage of stainless steel elbow should be regularly inspected, the exposed processing surface should always be kept clean, remove dirt, and neatly stored in a dry indoor ventilation, stacking or open storage is strictly prohibited, always keep the stainless steel elbow dry and ventilated, keep the guard ring clean and tidy, and stored in accordance with the exact storage method.
