What is your delivery time?

Standard parts take 7-15 days, while non-standard parts take 15-25 days.

How to custom-made (OEM/ODM)?

Send us a new product drawing or sample, and we can custom-make the hardware as required while providing professional advice to maximize performance.

Which mode of transport would be better?

In general, sea freight is recommended as production is heavy, but we respect your views on other transportation modes as well.

Key features

Ultimate Heavy-Duty Large Diameter Capability: Specialized in manufacturing oversized sizes up to 3-5/8"

demonstrating advanced hot-forging and heavy rolling capabilities essential for massive pressure vessel and heat exchanger flanges.

Certified ASTM A193 B7 High Tensile Strength: Crafted from premium chromium-molybdenum (AISI 4140/4142) alloy

delivering a verified minimum yield strength of 105 ksi and tensile strength of 125 ksi to withstand extreme pipeline pressures.

Precision Black Oxide Finish for Smooth Assembly: The dark oxide coating provides excellent corrosion resistance and absorbs lubrication, dramatically reducing galling (cold welding) risks

Full Thread Design for Maximum Shear Resistance: Continuous full-body threading ensures uniform load distribution and high shear strength, minimizing stress concentration at the shank

eliminating installation failures in high-vibration environments.

Absolute Project Safety & Traceability: Each batch is supplied with a complete EN 10204 3.1 Mill Test Certificate, guaranteeing full chemical composition and mechanical property compliance
