Haihao Group Supplies Custom 316L Stainless Steel Counter Flanges to Spain
Haihao Group recently completed the production and shipment of a batch of custom 316L stainless steel counter flanges for a client in Spain. These products were manufactured strictly according to the customer’s engineering drawings and tolerance requirements, ensuring accurate installation and reliable sealing performance in demanding piping systems.
The order included several large-diameter counter flanges with the following specifications:
| Product | DN Size | Material |
| Counter Flange | DN300 | AISI 316L |
| Counter Flange | DN600 | AISI 316L |
| Counter Flange | DN900 | AISI 316L |
All products were produced based on customer drawings, with dimensional tolerances and drilling requirements carefully controlled throughout manufacturing and inspection.
Why 316L Stainless Steel Counter Flanges Are Widely Used
The main keyword for this project is 316L stainless steel counter flanges, which are commonly used in industries requiring excellent corrosion resistance, dimensional stability, and long-term reliability.
Compared with standard carbon steel flanges, 316L stainless steel counter flanges provide better resistance to:
- Chloride corrosion
- Humid marine environments
- Chemical processing media
- Low-temperature operating conditions
- Oxidation and rust formation
Because of these advantages, 316L stainless steel counter flanges are frequently selected for offshore projects, desalination plants, water treatment systems, food processing pipelines, and chemical installations across Europe.

Manufacturing According to Customer Drawings
One of Haihao Group’s core strengths is custom manufacturing based on technical drawings and project specifications.
For this Spanish project, the counter flanges required:
- Precise drilling positions
- Strict flatness tolerance
- Accurate bolt hole alignment
- Smooth machined sealing surfaces
- Large-diameter dimensional control
Our engineering and QC teams carefully reviewed every production step to ensure the final products matched the customer’s design requirements.
The drilling layout and machining accuracy are especially important for large-size custom stainless steel counter flanges, because even small dimensional deviations can affect installation and sealing performance.
