Key Deliverables and Features

1.Custom Manufacturing and Compliance

All components were produced according to the client’s construction drawings, ensuring precise dimensions and design requirements.

The flange and coupling were treated with hot-dipped galvanization for enhanced corrosion resistance and durability in harsh environments.

2.Assembly and Certification

The components were pre-assembled to simplify installation at the client’s site.

An EN 10204-3.1 material certificate was provided for all parts to ensure traceability and compliance with international standards.

3.Tailored Materials for Performance

The use of ASTM A105 steel with galvanization for key components ensures strength and durability.

Brass material for the threaded adapter offers excellent corrosion resistance, particularly in marine and offshore applications.

Non-asbestos fiber gaskets with NBR binder provide effective sealing for fluid transfer under moderate pressure.
