Built for Field Welding and Export Transit
Bevel-End Preparation to ANSI B16.9Every elbow end is machined on our dedicated bevel end line, holding land thickness and bevel angle within ANSI B16.9 tolerance. This matters most on multi-source projects - a bevel that's out of spec forces your site welders to re-grind before they can run a root pass, adding time to every joint. Consistent bevel geometry lets your welding crew move straight to fit-up on delivery. |
Shot Blasting + Anti-Corrosion CoatingBefore coating, inner and outer surfaces pass through our shot blasting equipment, which strips mill scale and surface oxide down to bare metal. We then apply anti-corrosion paint in black or color finish. This two-step process is standard on every carbon steel and alloy steel fitting we export - skipping it is what leads to rust bleeding through paint within months of installation in humid or coastal sites. |
Export Packaging Sized to Protect Bevel EndsSizes 8" and below ship in plywood cases, capped at roughly one metric ton per case so a single box stays within standard forklift and manual handling limits. From 10" up, elbows go on plywood pallets; from 24" up, each piece is individually crated to keep bevel faces and coating from contacting adjacent fittings during transit. Every case carries a label with size, steel grade, and batch number for traceability at your yard. |

Elbows are formed on our medium-frequency pushing lines and finished on the equipment shown above - see the full line-up on our production equipment page. Manufacturing quality is verified under three certified management systems, detailed on our certificate page:
| System | Standard | Certificate No. | Valid Through |
| Quality Management | ISO 9001:2015 | 1952024Q0837R0S | Sep. 9, 2027 |
| Environmental Management | ISO 14001:2015 | 1952024E0437R0S | Sep. 9, 2027 |
| Occupational Health & Safety | ISO 45001:2018 | 1952024S0379R0S | Sep. 9, 2027 |
All three certificates carry the same unified social credit code (91120116MA06U54G6F), issued Sep. 10, 2024, covering sales and manufacturing of steel pipe and pipe fittings.

Frequently Asked Questions
We produce weld on pipe elbows from 1/2" to 36" in seamless construction and 5" to 110" in welded construction, across 45°, 90°, and 180° angles in both long radius (LR) and short radius (SR). Wall thickness runs from Sch10 through Sch160, plus Std, XS, and XXS.
A234 WPB is forged carbon steel for general pressure piping at moderate to high temperature, produced per ASTM A234. API 5L grades (GR B through X70) are line pipe grades with defined yield strength, used on oil and gas transmission lines. We manufacture both grade families across the same 1/2"–110" size range - tell us your line pipe spec and we match elbow grade to it.
Manufactured as per ANSI B16.9, MSS SP 75, EN10253-2, and JIS B2313, covering US, European, and Japanese piping code references on the same physical elbow - useful when your project mixes documentation standards.
MOQ starts at 1 piece. Standard lead time is 15 working days for stocked sizes and grades; peak season (Q3–Q4) runs up to 30 days for larger or custom orders. Submit your quote request with size and quantity for an exact date.
Inner and outer surfaces are shot-blasted to remove mill scale, then coated with anti-corrosion paint in black or color finish. This two-step process is standard on every carbon steel and alloy steel fitting we export.
8" and below ship in plywood cases, capped around one metric ton per case; 10" and above ship on plywood pallets; 24" and above is individually crated. A 20GP holds roughly 20 standard cases (18–22 tons); a 40HQ holds roughly 40 (26–28 tons), depending on size mix.
Yes. Send us your drawing or line spec - bevel angle, land thickness, coating color, or export marking - and we quote against a sample confirmation before batch production.
