Types and Features of Corrosion-resistant Steel Pipe
| Product name | Features |
|---|---|
| Carbon Steel Pipe for Plumbing (“White Tube”) | This steel pipe, which is galvanized both inside and outside, offers outstanding workability. |
| Galvanized Steel Pipe for Water Piping (SGPW) | This steel pipe, which is thickly galvanized both inside and outside, offers outstanding workability. |
| PFP (Polyethylene-Lined Steel Pipe for Water Supplies) | This corrosion-resistant steel pipe for water supplies is coated on the inside with powdered polyethylene (PE). It boasts excellent quality, hygiene, and corrosion-resistance. It can be used for thread rolling. |
| JLP (PVC-Lined Steel Pipe for Water Supplies) | This corrosion-resistant steel pipe for water supplies is made by lining the inside of steel pipe with PVC pipe using a bonding agent. It is ideal for applications that require a high level of corrosion protection. |
| JDLP (PVC-Lined Steel Pipe for Building Wastewater Services) | This is lightweight steel pipe lined with PVC to address the need for more flexible and lighter structures as a result of the diversification of wastewater services and the increasing height of high-rise buildings. These products are compatible with WSP-042 (PVC-Lined Steel Pipe for Wastewater). |
| PLP-PE2S (Polyethylene-Coated Steel Pipe) | The outside of this corrosion-resistant steel pipe for underground piping is seamlessly coated with polyethylene resin by extrusion, to achieve a high degree of corrosion-resistance. Compatible with JIS G 3477-2 PE2S. |
| PLP-PE1H (Single-Layer Bonded Polyethylene-Coated Steel Pipe) | This single-layer bonded polyethylene-coated steel pipe is made by strongly bonding a polyethylene coating onto steel pipe. It is suitable for laying underground and is compatible with JIS G 3477-2 PE1H. |
| PLS (Small-Diameter Single-Layer Bonded Polyethylene-Coated Steel Pipe) | This small-diameter single-layer bonded polyethylene-coated steel pipe retains the corrosion-resistance of PLP and can be used with its coating for thread cutting and thread rolling. Compatible with JIS G 3477-2 PE1H. |
| PLV (PVC-Coated Steel Pipe) | This is an integrally molded product made by strongly bonding PVC to steel pipe. It can be used for cutting and thread cutting without the coating peeling off and is also suitable for thread rolling. The use of highly weather-resistant PVC enables use for both underground and exposed piping. |
| Fire-Fighting Pipe VS (Exterior PVC-Coated Steel Pipe for Fire Fighting) | Fire-Fighting Pipe VS conforms to WSP-041 (Exterior PVC-Coated Steel Pipe for Fire Fighting). It is used for buried fire-fighting water pipe and interconnected water piping. |

15Ａ～100Ａ | SGP |
| Main features and applications | ||
| 1)This is steel pipe coated on the inside by the fusion of polyethylene powder.This is steel pipe coated on the inside by the fusion of polyethylene powder. 2)Used for water supply piping (including chilled water piping) at temperatures up to 40°C. Not recommended for wastewater. 3)Available in three grades according to the degree of corrosion-resistance of the pipe exterior: PA (primer of rustproof paint), PB (zinc coating), and PD (single-layer PE coating). Generally, PA is used for indoor applications, PB for indoor and outdoor applications, and PD for buried piping. 4)Can be used for rolled thread with excellent earthquake-resistance. 5)Coating thickness is approximately 0.5 mm, resulting in a larger cross-sectional area than other kinds of lined steel pipe, and therefore less pressure drop. 6)Excellent cold resistance. 7)Excellent recyclability (without the need for separated waste collection) |
