1.5-inch And 2-inch Carbon Steel Electrical Conduit Pipes

We specialize in1.5-inch (DN40) and 2-inch (DN50) carbon steel electrical conduit pipes. Made of high-quality Q235/Q195 carbon steel, the pipes are processed through precision welding, rounding, rust removal and galvanized anti-corrosion treatment. They are professional cable protection pipes for building electromechanical projects, fire protection engineering, industrial power distribution and municipal weak current projects.

Complying with national standards and ASTM international specifications, our conduits feature uniform wall thickness, high strength and excellent toughness. They fully protect wires and cables from abrasion, extrusion, moisture and corrosion, suitable for various complex indoor and outdoor construction scenarios.

1. Premium Material & Long Service Life

Adopting national standard carbon steel base material with pure texture and stable mechanical properties, the pipes have excellent compression resistance, impact resistance and bending resistance. They resist deformation and cracking under external pressure such as construction trampling and wall extrusion, ensuring long-term stable service in engineering projects.

2. Superior Anti-corrosion Performance

With hot-dip/cold galvanized double anti-corrosion technology, the uniform and dense internal and external coatings isolate air, moisture and acid-base corrosion. The pipes adapt to harsh environments including damp basements, outdoor open areas, chemical plants and coastal high-salt fog areas, preventing rust and aging effectively.

3. Exquisite Workmanship & Smooth Wiring

The smooth and burr-free inner wall reduces wire threading resistance and avoids damaging cable insulation during construction, greatly improving wiring efficiency. The high-precision pipe body perfectly matches elbows, joints and junction boxes, ensuring easy and tight installation.

4. Standard Sizes & Wide Versatility

1.5-inch and 2-inch are mainstream engineering specifications with accurate dimensions. The 1.5-inch (DN40) conduit is ideal for high-current power cables and multi-group weak current lines; the 2-inch (DN50) conduit is suitable for main power distribution in factories, main wiring of large buildings and fire linkage lines, covering civil, industrial and municipal engineering needs.

5. Flame Retardant & Safe Compliance

Made of non-combustible carbon steel with high temperature resistance and leakage prevention, the pipes isolate safety hazards caused by short circuits and wire fires. They fully comply with fire protection and electrical construction codes, being the preferred compliant choice for commercial and infrastructure projects.
