Centrifugally Cast Iron Pipe

Our centrifugally cast iron pipes deliver exceptional performance. They ensure superior fluid transport. These pipes resist corrosion effectively. Their long service life reduces costs. Choose our reliable piping solutions.

We use precision centrifugal casting.
This gives you uniform wall thickness.
The internal structure stays dense and strong.
You get better flow and steady performance.

Our pipes resist corrosion very well.
We add custom inner and outer coatings.
They fight chemical damage and wear.
The pipes can last over 50 years.

We use high-quality EPDM or NBR rubber rings.
The flexible joints do not leak.
They allow pipe movement during earthquakes.
This reduces your repair worries.

Our pipes are lighter than old cast iron pipes.
You can install them quickly.
Push-on and flanged joints save labor time.
Your project finishes faster.

Ductile iron pipes handle high pressure easily.
They work up to PN40 rating.
Use them for tall buildings or long water lines.
They stay safe and reliable.

Our pipes are eco-friendly.
We use 100% recyclable raw materials.
This meets green building standards.
You help the environment too.

We mix quality raw materials. The furnace melts everything. Molten iron enters spinning molds. Centrifugal force spreads it evenly. This creates perfect pipe walls. We control cooling speed carefully. This ensures optimal microstructure. Each pipe gets individual inspection.

For city projects, our pipes meet strict standards.
Flexible joints handle ground movement well.
You get fewer leaks and lower maintenance costs.

For factory piping, we use strong coatings like epoxy.
These pipes handle chemical wastewater and cooling water.
They last a long time in tough conditions.

For farms and water conservancy, we offer high pressure pipes.
They resist wear from sand and soil.
Water flows steadily for irrigation.

For sewage treatment plants, we use cement or epoxy coatings.
These coatings fight acid and alkali damage.
Your pipes stay safe in harsh sewage environments.

Standard coating uses zinc-aluminum. Bitumen coating provides extra protection. Polyethylene suits special environments. Epoxy resin linings available. Ceramic epoxy resists abrasion. Coal tar epoxy handles chemicals. We customize for your needs.

We test every pipe with hydrostatic pressure.
Test pressure is at least 1.5 times working pressure.
No leaks are allowed.

We use ultrasonic testing to find internal defects.
We measure wall thickness to ensure uniformity.

We test coating adhesion and hardness.
This ensures long coating life.

We hold ISO 9001, CE, and SGS certificates.
We welcome on-site witness inspections for big projects.

We trace all raw materials.
You can see inspection reports for iron ore and metals.

Thirteen years industry experience. From small workshop to modern factory. Semi-automatic production lines. Large configuration warehouses. Professional management team. Strict quality control systems. Continuous technology innovation.

Base Materials
Ductile iron (EN-GJS-400-15 or ASTM A536) gives high strength.
It has tensile strength over 400MPa and 15% elongation.
This works well for high pressure and earthquakes.

Grey iron (ASTM A48 Grade 30/35) offers high hardness.
It resists wear and costs less.
Use it for low-pressure drainage and irrigation.

Inner Coatings
Cement mortar (C2/C3 grade) works for standard water supply.
Food-grade epoxy resin is safe for drinking water.
PU coating resists abrasion well.

Outer Coatings
Bitumen stops corrosion.
Epoxy zinc-rich paint fights industrial corrosion.
HDPE layer protects against UV and physical damage.

Standards We Follow
EN 545 for water pipelines
EN 598 for sewerage systems
ASTM A795 for cast iron pressure pipe
ISO 2531 for water applications
We can also meet custom standards for your country.

You can use our pipes for:

City water supply and sewage networks
