A 45° elbow is a commonly used directional pipe fitting in pressure piping systems, used to achieve a smooth 45° directional change in the pipeline. Compared with a 90° elbow, it offers lower fluid resistance, which helps reduce system energy consumption. The product is available in two curvature types: long radius (LR) and short radius (SR), and supports multiple connection forms including butt welding, socket welding, threaded, and flanged connections. Materials cover carbon steel, stainless steel, alloy steel, and more, and the product can be manufactured to Chinese national standards, American standards, and European standards. It is widely used in projects such as petrochemical, electric power and thermal energy, oil and gas transmission, municipal fire protection, and wastewater treatment, and is suitable for pipeline obstacle avoidance and smooth transition layouts.
Our 45° elbows come in a complete range of specifications, covering the full bore range of DN15-DN1200 and multiple SCH wall thickness grades to meet different pressure level requirements. Both long radius and short radius curvature types are available to suit different spatial and fluid requirements. Materials can be selected from carbon steel, stainless steel, and alloy steel, suitable for working conditions involving high temperature, high pressure, and corrosive media. Mature hot pushing and extrusion forming processes are adopted, resulting in uniform wall thickness and high dimensional accuracy, and non-destructive testing can be carried out. Multiple standards are supported, including Chinese national standards, American standards, and European standards, and special customization such as reducing, thickened wall, thermal insulation, and wear-resistant types can be provided to meet project-specific needs.
45° elbows are widely used in pressure pipeline projects such as petrochemical, oil and gas transmission, thermal power generation, coal chemical industry, seawater desalination, new energy projects, municipal fire protection, water supply and drainage, and wastewater treatment. They are suitable for smooth pipeline directional changes and for avoiding building structures and equipment facilities, and are mostly used for process pipeline layout adjustment, new construction of plant pipe networks, and retrofitting, repair, and maintenance of old pipelines. They can be adapted to above-ground process pipelines, buried pipe networks, and inlet and outlet connections of equipment units, meeting diverse working conditions such as high temperature, high pressure, and partially corrosive media.
The product is available in two curvature types: long radius LR and short radius SR. Connection forms include butt welding, socket welding, threaded, and flanged. Materials include carbon steel, stainless steel, alloy steel, and more. The bore range is DN15-DN1200. Standards implemented include Chinese national standards, American standards, and European standards. Specific parameters such as wall thickness and pressure rating can be confirmed based on project requirements. Please feel free to contact us with detailed specifications for quotation.
For regular in-stock 45° elbows, orders starting from just 1 piece are accepted, suitable for project material replenishment and small-batch procurement. For non-standard custom products such as large-diameter, thick-wall, and alloy steel types, minimum order quantities apply, and the specific quantity depends on the actual specification. In-stock orders will be shipped within 1-3 working days after confirmation. Ordinary custom products have a production cycle of 7-15 working days. Complex custom products such as large-diameter and thick-wall types have a delivery cycle of 15-30 working days. Foreign trade orders require additional time for packing, booking, and customs declaration. Mixed container loading of multiple types of pipe fittings is supported, and full-container orders offer price advantages.

Exported products are printed with shipping marks and include desiccant, and fumigation treatment can be provided.
We provide professional selection and technical consultation services to assist customers in verifying parameters such as curvature, bore size, wall thickness, and material. Products undergo dimensional and appearance inspection before leaving the factory. If non-artificial quality issues arise, after-sales handling will be provided in accordance with the contract terms. Technical documents such as material certificates, non-destructive testing reports, and export documentation can be provided upon request, and logistics shipping status is tracked in parallel. Online technical support is available to answer questions regarding product use and storage.
For normal working conditions, long radius (LR) elbows are preferred as they offer lower fluid resistance; short radius (SR) elbows can be selected when space is limited; for high-pressure working conditions, a design review is required. It is recommended to provide parameters such as nominal diameter, wall thickness, material, medium, and pressure, and we can assist in confirmation.
We can execute standards such as national standards (GB), American standards (ASTM/ANSI), European standards (EN), and others, and can perform non-destructive testing (NDT) as required, issuing documents such as material test reports (MTR). Specific testing requirements can be confirmed in the order.
For regular in-stock items, shipment will be made within 1-3 working days after order confirmation; for ordinary customized items, the production cycle is 7-15 working days; for complex customized items such as large-diameter and thick-wall products, the delivery lead time is 15-30 working days. For foreign trade orders, additional transportation and customs clearance time must be considered.
