Built for Severe Corrosion Conditions

In highly corrosive environments, standard stainless steel flanges often fail over time. Hastelloy flanges are specifically selected for applications where resistance to acids, chemicals, and extreme conditions is critical.

At Senrui, we supply Hastelloy flanges for projects where reliability is more important than cost — especially in chemical processing, acid handling systems, and high-temperature operations.

  Where Hastelloy Flanges Are Used

Our Hastelloy flanges are commonly used in:

• Chemical processing plants
• Sulfuric acid and hydrochloric acid systems
• Pharmaceutical production lines
• Waste treatment and environmental systems
• High-temperature and corrosive fluid pipelines

These applications require materials that can maintain performance under continuous chemical exposure.

  Common Hastelloy Grades We Supply

Different environments require different alloy grades:

• Hastelloy C276 flange – excellent overall corrosion resistance
• Hastelloy C22 flange – strong resistance to oxidizing chemicals
• Hastelloy B2 flange – suitable for reducing environments (acid systems)
• Hastelloy C2000 flange – enhanced versatility for mixed acid conditions

We can also produce according to specific project requirements or material specifications.

  Size & Pressure Capability

• Size range: 1/2” to 48”
• Pressure class: 150# to 2500#

Custom dimensions and special designs are available for project-based orders.

  Manufacturing & Quality Control

Hastelloy materials are costly, and processing requires strict control.

Our production includes:

• Certified raw material sourcing
• Precision forging and machining
• Heat treatment control
• Dimensional inspection
• Surface quality inspection

Each flange is inspected to ensure it meets project requirements before delivery.

  Export Experience

We have supplied Hastelloy flanges to:

• Chemical plants in Southeast Asia
• European industrial distributors
• Middle East engineering contractors

We understand packaging, documentation, and export requirements for high-value materials.

  What is Hastelloy C276 flange used for

Hastelloy C276 flanges are widely used in chemical processing and acid environments due to their excellent corrosion resistance.

  Why choose Hastelloy instead of stainless steel

Hastelloy offers significantly better resistance to strong acids and corrosive media compared to standard stainless steel.

  Is Hastelloy suitable for sulfuric acid

Yes, certain grades like C276 and C22 perform well in sulfuric acid environments depending on concentration and temperature.

  What industries use Hastelloy flanges

Common industries include chemical processing, pharmaceuticals, environmental engineering, and high-temperature systems.

  Can you supply custom Hastelloy flanges

Yes, we support custom production based on drawings and application requirements.
