90° elbows are mainly used in pressure piping systems to achieve a 90-degree right-angle turn in the pipeline, changing the flow direction of the medium being conveyed. They are widely applied in various engineering projects such as chemica
Inquiry
A 90° elbow is a key pipe fitting in pressure piping systems for achieving a 90° right-angle turn in the pipeline. It is available in two mainstream curvature types: long radius and short radius, and supports multiple connection methods such as butt welding, socket welding, and threading. The material coverage includes carbon steel, stainless steel, and alloy steel. It is suitable for engineering projects in chemical, power, oil and gas, municipal, and sewage treatment industries, and is a commonly used pipe fitting for EPC general contracting, pipeline construction, industrial and mining enterprises, and foreign trade procurement. We provide two curvature types: long radius (LR, R=1.5D) and short radius (SR, R=1.0D), as well as multiple connection forms including butt welding, socket welding, threading, and flanging, to meet different space and working condition requirements. The materials cover carbon steel, stainless steel, and alloy steel, and support non-standard customization. Production can be carried out according to standards such as GB, ASME, and EN. The products are manufactured using hot pushing and extrusion forming processes, with uniform wall thickness to ensure reliable quality. We provide complete pre-sales selection guidance, after-sales technical support, and logistics tracking services to ensure smooth procurement and delivery.

A 90° elbow is a commonly used pipe fitting in pressure piping systems. Its main function is to achieve a 90° right-angle turn in the pipeline, changing the direction of the medium flow. According to the radius of curvature, it is divided into long radius (LR, R=1.5D) and short radius (SR, R=1.0D). The long radius elbow has low fluid resistance and is the mainstream choice in engineering; the short radius elbow is suitable for working conditions with limited space. Connection methods include butt welding, socket welding, threaded, and flanged. Materials cover carbon steel, stainless steel, and alloy steel, and can meet the needs of various engineering projects such as chemical, power, oil and gas, municipal, and sewage treatment.
Our 90° elbows have the following core advantages: complete material range, with carbon steel, stainless steel, and alloy steel available, adapting to different working conditions such as high temperature, high pressure, and corrosion; complete specifications, with both long radius and short radius available, full DN nominal diameter coverage, multiple SCH wall thickness options, and support for non-standard customization; reliable process, using hot pushing and extrusion forming, with uniform wall thickness and stable quality; diverse connection methods, with butt welding, socket welding, threaded, and flanged connections all available, adapting to different piping systems; comprehensive implementation standards, complying with domestic and international standards such as GB/T12459, GB/T13401, ASME B16.9; strong customization capability, supporting special requirements such as reducing diameter, thickened wall, wear-resistant lining, and prefabricated insulation.
90° elbows are widely used in pressure piping projects such as petrochemical, oil and gas transportation, thermal and thermal power generation, new energy projects, municipal fire protection, water supply and drainage, sewage treatment, coal chemical, seawater desalination, etc. They are suitable for working conditions such as above-ground pipelines, buried pipe networks, and equipment unit connections, used for right-angle turns in pipelines. Long radius elbows are used for general engineering, while short radius elbows are used in spaces with limited area.
The main specification parameters include: bending radius (long radius LR R=1.5D, short radius SR R=1.0D), nominal diameter DN (full range), wall thickness grade SCH (Sch10-Sch160), material grade (carbon steel, stainless steel, alloy steel, etc.), connection type (butt welding, socket welding, threaded, flanged), implementation standard (GB/T12459, GB/T13401, ASME B16.9), surface treatment (rust removal, black paint, galvanizing, anti-corrosion treatment). Specific dimensions and material grades can be confirmed according to project requirements.
Conventional standard stock specifications support small batch purchasing, and stock items can be ordered starting from a single piece; non-standard, large-diameter, thick-wall, and alloy steel special material orders have minimum order quantity requirements. Batch orders have better pricing advantages, and foreign trade export can be shipped by full container or LCL (less than container load). Conventional standard stock specifications are shipped within 1-3 working days after order confirmation; ordinary standard non-standard customized products take 7-15 working days; large-diameter, thick-wall, alloy steel, and special anti-corrosion and insulation customized products take 15-30 working days. Foreign trade orders are coordinated with production, customs declaration, and packing cycles, and production scheduling can be coordinated according to the project schedule, with specifics subject to contract confirmation.
We provide product technical consultation and selection guidance, assisting customers in verifying the matching of specification parameters with working conditions. Products undergo strict inspection before leaving the factory, and if non-human quality issues occur, after-sales handling is provided according to the contract agreement. Technical documents, material certificates, inspection reports, and other document support can be provided. We follow up on order logistics information throughout the entire process, assist in checking packing and shipping mark documents for foreign trade orders, answer installation and usage questions, and provide supporting technical services for engineering projects and export orders.
The bending radius of a long radius elbow (LR) is 1.5D, offering low fluid resistance and making it the mainstream choice in engineering; the bending radius of a short radius elbow (SR) is 1.0D, suitable for space-constrained working conditions.
We support standards such as GB, ASME, and EN, with materials covering carbon steel, stainless steel, alloy steel, etc. Specific grades can be confirmed based on project requirements.
For regular in-stock specifications, shipment is within 1-3 working days after order confirmation; for ordinary non-standard custom products, 7-15 working days; for custom products such as large diameter, thick wall, and alloy steel, 15-30 working days. The specific timeline is subject to contract confirmation.
