Threaded (screwed) elbows are forged pipe fittings under the Guojie brand, which achieve pipe direction changes through threads on both ends without welding, making disassembly, installation, and maintenance very convenient. The products are mainly 90° and 45° short-radius elbows, and long-radius as well as non-standard 30°/60° angles can also be customized. Thread types cover NPT, BSPT, BSPP, G, etc., to suit different piping standards. A variety of materials are available, and customization requirements such as reducing sizes, extra thickness, and male/female threads are supported. The products comply with GB/T14383 and ASME B16.11 standards, feature precision thread machining and dense forged structure, and are suitable for small-diameter medium- and low-pressure auxiliary piping, instrument lines, fire protection, HVAC, and other applications. We provide both stock and customization services with flexible lead times; please contact us to confirm the specific configuration.
Overview
A threaded (screw-thread) elbow is a pipe fitting that changes the direction of a pipeline through threaded connection, requiring no welding and offering convenient assembly and disassembly. The product is mainly available in 90° and 45° short-radius types, is forged, and is suitable for small-diameter low-pressure pipelines. It complies with Chinese national standards and American standards, supports multiple thread standards, has ample stock, and can also be customized as required.
Key Features
No welding required, easy assembly and maintenance; forged construction, dense structure, and precise thread machining; supports NPT, BSPT, BSPP, G and other thread types; 90° and 45° short-radius types are readily available in stock; multiple material options available, supporting reducing, thickened, and internal/external thread customization; complies with GB/T14383 and ASME B16.11 standards, and inspection documentation can be provided.
Applications
Suitable for small-diameter medium- and low-pressure auxiliary pipelines, instrument lines, fire protection, HVAC, equipment auxiliary take-over, pipeline renovation and maintenance, and other scenarios. The main purchasing groups include EPC general contracting engineering companies, pipeline construction units, petrochemical and power industrial/mining enterprises, pipe fitting distributors, complete equipment manufacturers, and overseas foreign trade buyers.
Specifications
Core parameters include bending angle (mainly 90° and 45°, with 30°/60° requiring customization), radius of curvature (mainly short radius SR, with long radius LR available for customization), thread standard (NPT/BSPT/BSPP/G), nominal diameter, wall thickness class, material grade, etc. It complies with GB/T14383 and ASME B16.11 standards. Specific parameters need to be confirmed comprehensively based on the medium, temperature, and pressure; please feel free to contact us.
Procurement & Delivery
Standard stock specifications have a minimum order quantity of 1 piece, while large-diameter, thick-wall, alloy steel, and non-standard customized parts have a minimum order quantity. Standard stock delivery time is 1-3 working days, ordinary non-standard small- and medium-diameter items take 7-15 working days, and large-diameter or special-process items take 15-30 working days. Foreign trade orders reserve time for packing and customs declaration, and the specific delivery time is subject to the contract. Regarding packaging, small-diameter items are wrapped in anti-rust paper, placed in plywood wooden cases with shock-absorbing pads; medium- and large-diameter items are carried on solid wood pallets and wrapped externally with rain-proof stretch film; export packaging is printed with shipping marks, contains desiccant inside, and wooden cases support fumigation.
Service & Support
We provide technical guidance for product selection, helping distinguish connection methods such as butt welding and socket welding, and offer complete documentation for materials, inspection, and export. For non-artificial intrinsic quality issues of the body, we handle them according to the contract terms. We track logistics progress, and for foreign trade orders, we assist in checking the packing list and shipping marks. We also answer questions about storage and usage, but do not assume responsibility for quality issues caused by welding, modification, or misuse in product selection.
FAQ
How to choose between threaded elbows and welded elbows?
For small-diameter, medium- and low-pressure auxiliary pipelines, threaded elbows can be selected; they require no welding and are easy to assemble and disassemble. For high-pressure main lines, butt-welding elbows are recommended as the priority, as the welded integrality is better. Specific selection needs to be confirmed based on working conditions such as medium, temperature, and pressure; you are welcome to contact us for confirmation.
Can NPT, BSPT, BSPP, and G threads be interchanged?
No, they cannot. The thread profile angle, taper, and other parameters of NPT, BSPT, BSPP, and G threads are different and cannot be interchanged. Be sure to confirm the thread standard before placing an order, so as not to affect assembly and sealing.
What standard do threaded elbows comply with?
We comply with the GB/T14383 and ASME B16.11 forged fittings standards, support MT/PT non-destructive testing, and can provide inspection documentation.
Are 90° and 45° threaded elbows in stock? What is the lead time?
90° and 45° short radius threaded elbows are in stock, with a lead time of 1-3 working days. Long radius (LR), 30°/60°, etc. are custom-made items, with a lead time of 7-30 working days depending on the specific case, subject to the contract.
