90° Flanged Elbow
The 90° flanged elbow combines the fluid diverting function of an elbow with the quick-installation structure of a flange. When a pipeline needs a right-angle turn, the flanges at both ends are directly bolted together, eliminating the need for on-site hot work welding, making disassembly, assembly, and later maintenance more convenient. The product we manufacture covers three materials: carbon steel, stainless steel, and alloy steel. The bending curvature is available in long radius (1.5D) and short radius (1.0D). The flange face is precision-machined, and the bolt holes are arranged according to standards, so that after connection the sealing faces fit tightly. The product is manufactured according to general industrial standards such as ASME B16.9, ASME B16.5, GB/T12459, and HG/T20592. It is formed by integral forging, seamless stamping, and CNC precision turning. The inner wall of the flow channel is smooth, which helps reduce medium erosion and pressure loss. For standard DN15–DN200 carbon steel and 304/316L stainless steel stock items, re-inspection and shipment can be completed within 24 hours after order confirmation. Non-standard diameters, special wall thicknesses, thickened high-pressure pipe walls, non-standard bending curvatures, and surface treatments such as hot-dip galvanizing, sandblasting, and mirror polishing can all be customized according to project requirements.

45° Flanged Elbow
The 45° flanged elbow is an angled direction-changing pipe fitting we supply to the pipeline engineering market, integrating a 45° elbow direction-changing structure with flanged quick-installation connections. Compared with 90° elbows, the 45° angled bend is more targeted in fine-tuning pipeline slopes, misaligned connections, and dispersing fluid impact, making it suitable for occasions requiring control of pipeline stress, reduction of scale buildup, or avoidance of installation dead zones. The product is divided into two specifications: long radius 1.5D and short radius 1.0D, with nominal diameters covering DN15-DN2000, and pressure compatibility for national standard PN10-PN160 and American standard Class150-Class2500. Materials cover carbon steel, stainless steel, and alloy steel, and can be selected according to medium type, working temperature, and corrosion conditions. The flange face is precision machined, bolt hole positions are configured according to standards, and both single-flange and double-flange forms are supported. Regular carbon steel and stainless steel stock styles can be quickly arranged for shipment after order confirmation, while non-standard sizes, special materials, and surface processes can be customized according to project requirements.

180° Flanged Elbow
The 180° flanged elbow we provide has the flange ports integrally formed with the elbow, eliminating the need for on-site welding of flanges and reducing defects in the weld heat-affected zone.

Flange equal-diameter elbow
The flanged equal-diameter elbows we supply have flanges of the same diameter at both ends, and are connected to pipelines, valves, or equipment through bolts and sealing gaskets, without the need for on-site welding. The products are manufactured according to standards such as GB/T12459, GB/T9113, ASME B16.9, ANSI B16.5, etc. Materials can be selected from carbon steel, stainless steel, alloy steel, plastics, etc. Pressure ratings cover PN6 to PN100, Class150 to Class1500, and the media are suitable for water, steam, oil products, gas, acid-base chemical fluids. The equal-diameter design means the pipeline bore remains unchanged, with no diameter reduction and no additional throttling, making it suitable for working conditions involving simple direction changes. If you need to confirm the specific angle, diameter, material, or pressure rating, you are welcome to contact us for assistance with selection.

Long radius flanged elbow
Long-radius flanged elbows are among the most commonly used standard elbows in pipeline engineering, with the industry designation LR and a bending radius R=1.5D. Compared with short-radius elbows, their curvature is gentler, resulting in less turbulence and pipe-wall erosion when the medium passes through, which helps reduce scaling, vibration, and local pressure drop, making them suitable for long-distance transportation, high-flow-rate, and continuously operating pipelines. The flanges at both ends can be directly connected to pipes, valves, and pressure vessels via bolts and sealing gaskets, without the need for on-site welding, making later maintenance, cleaning, and modification more convenient. We produce according to standards such as GB/T12459, GB/T9113, ASME B16.9, and ANSI B16.5. Material options include carbon steel, stainless steel, alloy steel, and plastic, among others. Pressure ratings cover PN6 to PN100 and Class150 to Class1500, suitable for media such as water, steam, oil products, gas, acid-base chemical fluids, and sewage.

Integrally Cast Flanged Elbow
Integrally cast flanged elbows, also known as one-piece cast flanged elbows or cast steel flanged elbows, are formed in a single pour using an integral sand mold precision casting process, with no welding, splicing, or secondary assembly between the flange and the elbow body. Compared with ordinary welded flanged elbows, they structurally avoid common problems such as weld slag inclusion, porosity, cracks, and incomplete fusion, featuring high structural density and uniform wall thickness, and can withstand high pressure, high temperature, and continuous medium scouring. The products are available in three angles: 45°, 90°, and 180°, in two curvatures: long radius R1.5D and short radius R1.0D. Materials cover cast steel, ductile iron, stainless steel casting, and alloy casting. The flanges use bolted gasket connections, with flat sealing surfaces and precise bolt hole positions. They are suitable for high-pressure pipeline systems in mining, metallurgy, thermal power stations, high-pressure chemical engineering, oil and gas transportation, shipbuilding and heavy industry, pressure vessels, and special equipment. For specific diameters, pressure ratings, and material configurations, please contact us for confirmation.

Flanged Reducing Tee
A flanged reducing tee is also called a flanged reducing tee; all three ports are equipped with flanges and connect to the pipeline through bolts and sealing gaskets, so no welding is required on site. It combines the two functions of branching and reducing into a single pipe fitting, making it suitable for pipeline systems where the main pipe diameter is large and the branch pipe diameter is small. The internal flow passage transitions smoothly, which helps reduce medium turbulence and pressure loss. The product can be manufactured by hot pressing, forging, or integral casting, and complies with standards such as GB/T12459, GB/T9113, HG/T21635, ASME B16.9, and ANSI B16.5. Materials cover carbon steel, stainless steel, alloy steel, and ductile iron, and pressure coverage includes PN6 to PN100 and Class150 to Class1500. For specific specifications, materials, and flange sealing face forms, please contact us for confirmation.

Flanged Y-type tee
The biggest difference between a flanged Y-type tee and an ordinary right-angle tee lies in the flow passage angle. The medium transitions more smoothly in the Y-shaped inclined flow passage, resulting in less turbulence and smaller local pressure drop, and the pipe wall erosion and pipeline vibration noise are also reduced accordingly. All three ports adopt an integrated flanged structure, and on site they can be connected with bolts and sealing gaskets without welding, making disassembly, assembly, and maintenance convenient, and there is no hidden risk of weld seam leakage. The flanged Y-type tees we produce comply with standards such as GB/T12459, GB/T9113, HG/T21635, ASME B16.9, ANSI B16.5, etc., with pressure coverage from PN6 to PN100 and Class150 to Class1500, and materials covering carbon steel, stainless steel, alloy steel, and ductile iron.
