Stainless steel flange performance
Stainless steel flanges do not cause corrosion, pitting, rust, or wear. Stainless steel is one of the strongest materials in building metal materials. Because stainless steel has good corrosion resistance, it enables structural components to permanently maintain engineering integrity. The chrome-plated stainless steel stamping flange also combines mechanical strength and high extensibility, making it easy to machine parts to meet the needs of architects and structural designers. All metals react with oxygen in the atmosphere to form an oxide film on the surface.
Stainless steel flanges and other steel butt welded pipe fittings, forged pipe fittings and steel flanges are sold. The main products are carbon steel, austenitic stainless steel and alloy steel, and other domestic and foreign high-quality pipe flanges, elbows and tees. Four-way), same (bias) heart reducer (size head), elbow, cap, forged socket weld and threaded pipe fittings. All products adopt American standard ASME (ANSI), German standard DIN, Japanese standard JIS, Chinese GB/T, JB, SH, HG and other standards. At the same time, we can also make various special, non-standard and extra-thick walls according to customer requirements. Series of stainless steel pipe fittings, stainless steel flanges and other pipe joints.
The stainless steel flange connection is to fix two pipes, pipe fittings or equipment to each one on a flange. The two flanges are added with pads and bolted together to complete the connection. Some fittings and equipment have their own flanges and are also flanged. Stainless steel flanges have threaded flanges and welded flanges. They are disc-shaped parts that are most common in plumbing and are used in pairs. In plumbing, flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed, and the low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. Low-pressure small-diameter wire-bonded flanges, high-pressure and low-pressure large diameters are all welded flanges. The thickness of the flanges of different pressures and the diameter and number of connecting bolts are different. Stainless steel flanges are resistant to corrosion, pitting, rust or wear and are among the strongest materials in construction metal materials. Because stainless steel has good corrosion resistance, it enables structural components to permanently maintain engineering integrity.
Flanges can not be stored for a long time, should be checked on time, often the exposed surface must be kept clean, remove dirt, neatly stored in a place where the room is dry and dry, no stacking or open storage. When the ball valve of the flange, the stop valve and the gate valve are used, they are only fully open or fully closed, and do not allow to adjust the flow rate, so as to avoid erosion of the sealing surface and accelerate wear. Flange is easy to manufacture, simple to manufacture, low in cost and widely used; but its rigidity is poor, so it should not be used in chemical process piping systems with high supply and demand, flammability, explosive and high vacuum requirements. The sealing surface type has a flat surface and a convex surface. The flange structure is simple, small in size and light in weight; it is compact and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and has good sealing performance. It is also widely used in the vacuum system; the maintenance is convenient, the ball valve structure is simple, and the sealing ring is generally active. It is convenient to disassemble and replace; when fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium.
