Product Description
Flange
A flange, also known as a flange plate (or connecting plate), is the most commonly used method for joining rail tracks to one another. When using bracket connections, all you need to do is weld a bracket onto the end of each of the two rails that are to be joined, and then connect the two brackets together with bolts. (Threaded flanges are not included.) Another method for connecting rails is to use rail joints. When using rail joints, after aligning the rails, countersinks should be drilled on both sides of the rails to accommodate tapered heads, and then the joints should be secured with set screws and nuts.
Product Features: Beautiful appearance, smooth surface, acid and alkali resistance, corrosion resistance, and excellent texture performance. Technical Parameters: Please refer to the technical white paper for pipe fittings. Packaging Method: Wooden crate with shock-absorbing film packaging or other methods. Surface Finish: Both inner and outer surfaces have mirror-like finish with Ra ≤ 0.8 μm; the inner wall undergoes mechanical polishing and electro-polishing with Ra ≤ 0.2 μm; the outer surface is either polished to a glossy or matte finish.
Product Application: The product undergoes high-grade polishing both internally and externally using advanced polishing equipment to meet stringent surface precision requirements. This product is widely applicable to stainless steel piping systems in industrial sectors such as food, beer, beverages, pharmaceuticals, and chemicals. We offer custom fabrication services based on customer-provided drawings or samples, enabling us to produce non-standard products tailored to specific customer needs.
Fluoroplastic-lined flange
Fluoropolymer-lined flanges: Connection fittings used in industrial applications for acid and corrosion resistance, suitable for handling toxic gases, corrosive gases, and corrosive liquids. Operating temperature: t ≤ 150°C. These flanges are not suitable for welding and typically employ screw connections. The inner lining material includes PO, PTFE, FEP, and PFA, offering a 99% resistance to acid and corrosion. They are commonly used for handling sulfuric acid, carbonic acid, chlorine gas, highly corrosive liquids, and toxic corrosive gases.
Welding flange
A butt-welding flange is a flange in which the pipe is inserted into the inner ring of the flange and then welded. Flat-welding flanges are divided into two types: flat-welding flanges with a neck and plate-type welding flanges.
Flat-welded flange
The advantages of flat-welded flanges are their simple manufacturing process and low cost; however, they require substantial welding effort, consume a large amount of welding rods, and cannot withstand high temperatures, high pressures, repeated bending, or temperature fluctuations. They are generally used in pipelines with PN ≤ 2.5 MPa, at ambient temperature, and operating temperatures t ≤ 0℃.
