High Performance Open Die Forging Flanges For Petrochemical Pipelines And Marine Engineering

High Performance Open Die Forging Flanges for Petrochemical Pipelines and Marine Engineering

Our open die forging flanges are designed to deliver exceptional strength, durability, and sealing reliability in demanding industrial environments. Manufactured from high-grade alloy and carbon steels, these flanges are forged under controlled processes to ensure a dense internal structure, uniform grain flow, and excellent resistance to pressure and corrosion.

Product Features:

• Precision open die forging ensures high structural integrity and long service life

• Superior resistance to stress, impact, and fatigue under continuous operation

• Available in a wide range of sizes, pressure classes, and material grades to meet customer-specific requirements

• Strict inspection and testing, including UT, MPI, tensile and hardness testing, to guarantee performance and safety

Application Fields:

• Petrochemical pipelines and refinery systems requiring leak-proof and high-strength connections

• Offshore and marine engineering projects exposed to harsh environments and high loads

• Shipbuilding, power generation, and heavy industrial equipment connections

• Critical joint applications where reliability and safety are paramount

With proven forging expertise and strict quality control, our flanges provide dependable performance in the world’s toughest working conditions.

Simplified Steel Forging Process

Material inspection and verification → Cutting to size → Controlled and uniform preheating → Open die forging with subsequent heat treatment → Initial inspection of forged blanks → Rough machining to approximate dimensions → Non-destructive testing (UT/MT) and hardness evaluation → Quenching and tempering to achieve desired mechanical properties → Detailed final inspection → Precision finishing as required → Component marking, identification, and protective packaging → Storage and shipment to client
