Why Buy This Elbow From Us
Four production and service advantages that translate into lower cost and faster delivery for your project
Full-Range Production Equipment
3 push-forming machines cover 3″–24″ elbows, plus 4 precision hydraulic presses for 1/2″–3″ - giving you one factory source for a full-diameter BOM instead of splitting orders across suppliers
Trained QC & Technical Team
Every elbow batch is inspected before shipment by trained technical staff, cutting the risk of dimensional non-conformance reaching your job site.
Year-Round Stock, Faster Dispatch
Common models are kept in stock all year; regular-size orders ship within 7–15 days - useful when your project schedule can't wait on a full production cycle.
Responsive Sales Support
7×12-hour coverage from staff with 2+ years' product experience, with an average response time under 2 hours for quotations and technical questions.
Configuration Options
Angle, radius, size and material combinations available on this product line.
Available in 45°, 90° and 180° bend angles, in both Long Radius (1.5D) and Short Radius (1.0D) configurations, plus 3D and 5D bend radii for specialized routing. Sizes span 1/2″–24″ seamless and 24″–48″ welded, wall thickness 2mm–60mm, in ASTM A234 WPB (20# carbon steel also producible). Not sure which combination fits your drawing? Send us your spec and we'll confirm availability.
Application Scenarios
Where this elbow is typically specified, and why it fits.
Oil & Gas Pipelines
Direction changes on gathering and cross-country lines need full-penetration joints that won't become a pressure-drop or leak point. The long-radius (1.5D) elbow gives a smoother flow transition than short-radius bends at these junctions.
Power Plant Piping
Steam and feedwater lines run at moderate-to-elevated temperatures. ASTM A234 WPB is specified for exactly this service range, so the same elbow grade serves boiler-house and turbine-hall piping without a material change.
Chemical & Petrochemical Processing
EPC specs typically call for ASME B16.9 dimensional compliance and documented QMS traceability. Production under our ISO 9001-certified system supports the paperwork your project documentation requires.
Municipal Gas & Water Supply
Utility branch and main lines cover a wide range of diameters. Our 1/2″–48″ range lets one order cover most of a municipal pipeline BOM instead of splitting across two suppliers.
Shipbuilding & Marine Piping
Engine-room and deck piping often has tight routing constraints. The Short Radius (1.0D) option is available where a long-radius bend won't fit the available space.
OEM / ODM Capability
We support OEM/ODM production on this elbow line: custom sizing within 1/2″–48″, custom wall thickness within 2mm–60mm, material grade switching (WPB / 20# / client-specified equivalent) and custom marking on request. MOQ starts at 1 piece for stock sizes; project-specific custom runs are quoted once drawings/specifications are confirmed.

Frequently Asked Questions
What sizes and wall thicknesses are available for this elbow?
Seamless construction covers 1/2″–24″, welded covers 24″–48″, with wall thickness from 2mm to 60mm. The elbow is available in 45°, 90° and 180°, in Long Radius (1.5D), Short Radius (1.0D), 3D and 5D configurations.
What temperature and pressure range is this elbow rated for?
ASTM A234 WPB is a wrought carbon steel grade intended for moderate-to-elevated temperature piping and pressure-vessel service. For a specific DN/PN or pressure-temperature rating matched to your project, please send us your working conditions for confirmation.
Which quality certifications does Tianjin Baode Steel hold?
ISO 9001:2015 Quality Management (No. 1952024Q0837R0S), ISO 14001:2015 Environmental Management (No. 1952024E0437R0S) and ISO 45001:2018 Occupational Health & Safety (No. 1952024S0379R0S), all issued Sep 10, 2024 and valid through Sep 09, 2027, plus AAA Credit Enterprise status.
What is the MOQ and lead time?
MOQ is 1 piece. Stocked common sizes ship in 7–15 days; standard production orders run 15 days, extending up to 30 days during peak season.
What if I receive a damaged or non-conforming elbow?
Every batch passes factory inspection before shipment, and the product carries a 1-year warranty against manufacturing defects (this excludes damage from improper handling, installation or operation). Contact our sales team with your order number and photos to start a claim; exact claim processing time will be confirmed by our after-sales team.
Can you produce custom sizes or branding for our project (OEM/ODM)?
Yes. We support custom dimensions, wall thickness, material grade and marking. MOQ starts at 1 piece for stock sizes; project-specific custom runs are quoted after your drawing or specification is confirmed.
How are the elbows packaged and shipped?
Small items are packed in wooden boxes, larger items on wooden pallets, then container-loaded: a 20GP holds roughly 20 wooden boxes (≈18–22 tons) and a 40HQ roughly 40 boxes (≈26–28 tons), varying by elbow size and wall thickness. Our factory is near Tianjin sea port with established forwarder relationships.
What payment methods do you accept?
Please confirm accepted payment terms (e.g. T/T, L/C) directly with our sales team when requesting your quotation, as terms can vary by order size and destination.
