As a high-volume manufacturer specializing in grooved pipe connection systems, we supply 2 inch rigid pipe couplings designed for large project requirements in fire protection, HVAC, industrial water networks, and general mechanical pipelines. Our production system supports stable bulk orders, consistent quality, and global compliance standards.
Our 2" rigid couplings lock the pipe ends firmly, ensuring a solid and vibration-resistant connection suitable for fixed piping applications.
They are widely used in:
Fire sprinkler systems (wet / dry / pre-action / deluge)
HVAC chilled water and cooling water loops
Industrial circulating systems
Water supply and general utility pipelines
OEM prefabricated modules and skid-mounted systems
The rigid design ensures precise alignment and effectively controls axial displacement, making it ideal for systems that require structural stability.
We produce the 2" rigid pipe couplings using ductile iron ASTM A536, providing excellent strength and durability.
Key technical advantages include:
Ensures long service life and supports high-pressure conditions required in firefighting and industrial systems.
EPDM for water-based systems (fire, HVAC)
NBR for oil, fuel, or chemical-related pipelines
Fusion-bonded epoxy (FBE)
Hot-dip galvanization
Custom colors for project or branding needs
Each product undergoes pressure, torque, hardness and sealing tests to ensure long-term stability.
For engineering contractors and system integrators handling regulated projects, our 2" rigid couplings can be supplied with:
UL Listed / FM Approved options
CE / UKCA for Europe
ISO 9001 quality system
Compliance with AWWA, EN 10242, ASTM standards
These certifications help your projects pass inspection smoothly, especially in the fire protection sector.
