Product Introduction

Stainless steel plate flat welding flange is a flange connector made of stainless steel plate, which is a commonly used pipeline connection flange


1. Excellent material: The stainless steel plate flat welding flange is made of high-quality stainless steel plate, which has excellent corrosion resistance and high temperature resistance, and is suitable for conveying various media.
2. Simple structure: The stainless steel plate type flat welding flange has a relatively simple structure, consisting of two flat flange pieces, with no raised threads or screw holes in the middle, making installation and disassembly convenient.
3. Reliable sealing: The stainless steel plate flat welding flange adopts a flat welding method, without the need for sealing gaskets. The sealing is directly achieved through the contact surface of the flange plate, ensuring the airtightness and liquid tightness of the connection.
4. Wide scope of application: stainless steel plate flat welding flange is suitable for connection of various pressure grades and pipe specifications, and is widely used in pipeline systems in petrochemical, Chemical engineering, pharmaceutical, food processing and other industries.
5. High strength: The flange made of stainless steel plate has good strength and stiffness, which can withstand significant pressure and temperature changes, ensuring the safe operation of the pipeline system.

Advantages and disadvantages:

1. Suitable for pipeline connections in high-temperature, high-pressure, and corrosive media, with good corrosion resistance.
2. Convenient and simple production, simple and compact structure, and convenient installation and maintenance.
3. After installation, the pipeline connection is tightened and reliable, and leakage is not easy to occur.
4. It has good sealing performance, which can effectively prevent medium leakage and ensure the normal operation of the system.
5. The flange connection has high load-bearing capacity and can meet the working requirements of the pipeline system.

1.Compared to other connection methods, plate type flat welding flanges need to consider the parallelism between the flange and the pipeline connection surface during installation, which has high process requirements.
2. Due to the susceptibility of welded joints to the influence of heat affected zone (HAZ), there is a possibility of welding deformation and residual stress.
3.When the pipeline system requires frequent disassembly, plate type flat welding flanges are not as convenient as threaded or quick installed flanges.
4. For the connection of large-diameter pipelines, flange connections may require the use of larger loads and the number of fastening bolts.

Overall, stainless steel flat welding flanges have reliable connection performance and good corrosion resistance, making them suitable for occasions with high requirements for pipeline connection safety and sealing. However, there are certain requirements for installation technology, and their applicability is relatively narrow.
