Flanges, also known as raised face plates or flanged disks, are components used to connect shafts or to join pipe ends. They are also used on equipment for connections between two devices, such as reducer flanges. A flange connection or flange joint refers to a removable connection formed by the combination of a flange, a gasket, and bolts. Pipe flanges are those used in piping systems, while equipment flanges refer to the inlets and outlets of equipment. Flanges have holes and bolts that secure them tightly together, with gaskets used to seal the spaces between them. Flanges come in threaded (screwed) connections, welding flanges, and clamp flanges. Flanges are typically used in pairs; low-pressure pipelines can use threaded flanges, while those above 4 kg pressure require welding flanges. Two flange disks are joined with a sealing gasket and then bolted together. Flanges of different pressures have different thicknesses and require different bolts. In the case of pumps and valves, the parts that connect to pipes are also made in flange shapes, known as flange joints. Any connection that uses bolts to join two flat surfaces and is sealed is generally called a "flange," such as the connections in ventilation ducts. These components can be referred to as "flange-type parts." However, such connections are only part of a device, like the connection between a flange and a pump, so it's not appropriate to call the pump a "flange-type part." Smaller items like valves can be called "flange-type parts."

The company continuously absorbs and digests technology during its development process, mainly producing: glass fiber reinforced polypropylene (FRPP) pipes, polypropylene (PP) pipes, high-density polyethylene (HDPE) pipes, PPH pipes, PVDF pipes, glass fiber reinforced polypropylene (FRP/PP) composite pipes, high-density polyethylene (HDPE) double-wall corrugated pipes, as well as a series of accessories such as elbows, tees, reducers, flanges, valves, plates, welding rods, and instrument pipeline valves. The company owns 4 sets of domestic production lines, 2 sets of German production lines, and produces pipes with diameters ranging from 15 to 900mm. It also imports 2 sets of Austrian installation equipment, 10 sets of domestic equipment, and establishes a department for engineering plastic pipeline installation to ensure the quality of after-sales service. The products feature corrosion resistance, light weight, high strength, anti-seepage, anti-aging, tensile and bending resistance, wear resistance, low flow resistance, low cost, long lifespan, and easy installation and maintenance. They are now widely used in engineering fields such as oil, chemical fiber, chemical industry, pharmaceuticals, papermaking, textiles, food, light industry, fire protection, environmental protection, metallurgy, mining, sewage treatment, and landfill.
