how to maintain Stainless steel threaded flange
Stainless steel flange has threaded flange and welding flange, it is a disk-like parts, in the pipeline engineering most common, flange is usually used in pairs. In pipeline engineering, flanges are mainly used for piping connections. In the pipeline which need be to connected, a flange will be installed, low pressure pipe can use wire flange, pressure above 4 kg will use welding flange. Low-pressure small diameter wire flange, high pressure and low pressure large diameter are used welding flange, different pressure flange thickness and connection bolt diameter and number are different.
Stainless steel threaded flange
Stainless steel Flange plate will not produce corrosion, pitting, rust or wear, is one of the highest strength materials in the building metal materials. Because of the its good corrosion resistance, it enables structural parts to permanently maintain the integrity of the engineering design.
Chromium-containing stainless steel flange tablets also combine both mechanical strength and high extensibility, easily for parts processing and manufacturing, can be satisfied with the needs of architects and structural designers. All metals react with oxygen in the atmosphere to form an oxide film on the surface.
In the maintenance of stainless steel flange is required to pay attention to a number of problems: long time use stainless steel flange need to be checked regularly, often exposed to the processing surface must be kept clean, clean dirt, neatly stored in the room ventilated dry place, is strictly prohibited from piling or open storage. Often keep the stainless steel flange dry and ventilated, keep the device clean and tidy, according to the accurate storage method storage.
When installing, the stainless steel flange can be installed directly on the pipe by the way of connecting, according to the position of use. Under normal circumstances, can be installed in any position in the pipeline, but need to facilitate the operation of the inspection, pay attention to the cut-off stainless steel flange medium flow should be longitudinal disc below to high, stainless steel flange can only be installed horizontally. Stainless steel flange in the installation should pay attention to sealing, to prevent leakage phenomenon, affecting the normal operation of the pipeline.
In order to prolong the service life of stainless steel thread flange, improve the quality of thread processing, in which processing and production should pay attention to a number of considerations: in the tap thread surface coated with titanium nitride coating, can significantly improve the tap wear resistance, heat resistance and lubrication, appropriate increase tap shovel back. However, it should be noted that, such as the shovel back too large, in the back of the knife is easy to plug into the back corner of the tap after the phenomenon, and the thread finish is not good; appropriate to increase the front corner of the tap, but should be noted that, if the tap before the angle is too large, It is easy to cause the taps to be broken and the threads are ribbed when the knife is retract.
