Flange shall be inspected regularly

Stainless steel flange connection is the two pipes, pipe fittings or equipment, first each fixed in a flange, between the two flange, plus pad, bolted together to complete the connection. Some pipe fittings and equipment has its own flange, also belongs to flange connection. Stainless steel flange has threaded connection flange and welding flange, it is a kind of disk parts, in pipeline engineering the most common, flange are used in pairs. In pipeline engineering, flanges are mainly used for connecting pipes. In the need to connect the pipeline, all kinds of installation of a flange, low-pressure pipeline can use wire flange, 4 kg above the use of pressure welding flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter are using welding flange, flange thickness of different pressure and connection bolt diameter and number is different. Stainless steel flange will not produce corrosion, pitting, corrosion or wear, is one of the highest strength materials used in the construction of metal materials. Because of its excellent corrosion resistance, stainless steel enables structural components to maintain the integrity of the engineering design permanently.

Flange can not be stored for a long time, should make regular inspection, often on the surface of the exposed processing must be kept clean, remove dirt, neatly stored in the indoor air dry place, do not pile or open storage. Flange ball valve, globe valve, gate valve use, only for full open or full closed, do not allow to do regulating flow, so as to avoid sealing surface erosion, accelerated wear. Flange materials convenient, simple manufacturing, low cost, widely used; But the rigidity is poor, therefore must not be used for supply and demand, flammable, explosive and high vacuum requirements of chemical process piping system and high, extremely harmful occasions. Sealing surface type has plane and protruding surface. Flange simple structure, small size, light weight; Close and reliable, the sealing surface material of the ball valve is widely used plastic, good sealing, and has been widely used in the vacuum system. Easy maintenance, ball valve structure is simple, the sealing ring is generally mobile, disassembly and replacement are more convenient; In fully open or fully closed, the sealing surface of the ball and seat is isolated from the media.
