Carbon Steel Flanges & Bolts
Heavy-Duty Carbon Steel Flanges & High-Tensile Bolts for Pipeline Integrity
Ensure a secure, rigid connection for your high-pressure piping systems with Luoyang Zhengju’s industrial-grade carbon steel flanges and bolts. Designed to bridge the gap between steel and polymer pipelines, our joining components are precision-engineered to provide a leak-proof seal under extreme mechanical stress, vibration, and thermal fluctuations in mining, energy, and infrastructure projects.
Precision Engineered Joining Components for Global Standards
We offer a complete suite of hardware designed for seamless integration with our HDPE, UHMWPE, and steel-lined pipes:
Carbon Steel Flanges: Available in Slip-on, Blind, and Weld-neck configurations. Our flanges are CNC-machined for perfect flatness, ensuring a uniform gasket compression that eliminates potential leak paths in high-pressure slurry or gas lines.
High-Strength Bolts & Nuts: Manufactured from premium alloy steels, our bolts provide the necessary clamping force to maintain joint integrity. We offer various grades (including 8.8 and 10.9) to match your specific torque and safety requirements.
Corrosion Protection: Choose from Galvanized, Epoxy Coated, or Zinc-plated finishes to ensure your hardware survives buried installations and corrosive mine water environments.
Reliability That Meets International Engineering Standards
In heavy industries like mining and oil transport, a single bolt failure can cause massive downtime. Our flanges and bolts offer:
Standard Compliance: Fully compliant with ANSI, ASME, DIN, and JIS dimensions, making them universally compatible with international pipeline equipment.
Ready-to-Ship Inventory: We maintain bulk stock of standard sizes to support rapid deployment and project continuity for EPC contractors worldwide.
