Why Buyers Choose This Elbow
 |
01
Dual Radius Options on One Production LineWe produce both Long Radius (R=1.5D) and Short Radius (R=1.0D) elbows on the same pushing and forming equipment - this means mixed-radius orders do not add a separate tooling changeover or extend your lead time. For layouts with tight fitting-to-fitting clearance, SR elbows reduce installed length; for flow paths where turbulence and pressure drop matter more, LR is the standard choice. |
|
02
Manufactured to Four International StandardsProduction drawings can follow ASME/ANSI (US), DIN (Germany), JIS (Japan), or GB (China) dimensional and tolerance requirements. For multinational EPC projects with mixed piping specs, this means one supplier can cover fittings destined for different regional code compliance without re-sourcing. |
 |
 |
03
Grade Range Beyond Standard 304/316In addition to the common WP304/304L and WP316/316L, we carry WP304H, WP316Ti, WP321/321H and WP347/347H for high-temperature or titanium/niobium-stabilized applications, plus low-temperature A402 WPL3/WPL6 and high-performance A860 WPHY grades for pipeline service. Tell us your service temperature and media, and we will confirm the correct grade before quoting. |
|
04
Every Batch Ships With Verifiable PaperworkEach order includes an EN 10204 3.1 mill test certificate covering chemical composition and mechanical properties. We also accommodate pre-shipment inspection by SGS, TÜV or BV when your project requires independent verification - see our certification page for our ISO 9001/14001/45001 credentials. |

Oil & Gas / Petrochemical PipingRefinery and gathering-line piping deals with corrosive media and cyclic pressure loads, so buyers need fittings verified against batch-level material data. Our WP316/316L elbows come with an EN 10204 3.1 MTC per batch, and higher schedules (XS through XXS) are available for elevated-pressure segments. This traceability is what most petrochemical QA departments ask for before approving a supplier. |

Inspection & Documentation

QC
Four Checks Before Every ShipmentStainless steel elbows fail in service for predictable reasons - wrong grade, undersized wall after forming, or out-of-tolerance center-to-end dimensions. Each of those is checked before the fitting leaves the floor.

Established in 2006 and renamed Tianjin Baode Steel Co., Ltd. in 2019, we produce seamless, ERW, LSAW and SSAW steel pipe alongside stainless steel, alloy steel and carbon steel elbows, tees, reducers and flanges. Fittings are exported to more than 40 countries and regions across North America, South America, Southeast Asia, the Middle East and Africa.
Production & Test Capability
|
Forming by size and grade
Pushing, pressing, forging or casting - the method is selected by diameter, wall thickness and grade, so a 3" Sch40s elbow and a heavy-wall 24" fitting do not share the same route. |
 Dimensional inspection
Center-to-end, ovality and post-forming wall thinning are measured against the governing standard - the three checks that decide whether a fitting welds in cleanly on site. |
Documentation
EN 10204 3.1 mill test certificate issued per batch, with SGS, TÜV and BV pre-shipment inspection supported when your project requires independent sign-off. |
