Kubota's ductile iron pipes are available in variety of size and for various needs.
Earthquake Resistant Joint
GX-typeDN75-DN400 (3"- 16")
*External coating: C-protect
*Lock ring is preset.
NS-typeDN500-DN1000 (20"- 40")
S-typePipe:DN1100-DN2600 (44"- 104")
US-typePipe:DN800-DN2600 (32"- 104")
UF-typeFitting:DN800-DN2600 (32"- 104")
T-type joint is push-on joint. It has flexibility and excellent water tightness.
K-type joint is mechanical joint. It has flexibility and excellent water tightness.
TLH-type is restrained joint. It is converted from T-type joint by providing the spigot with projection and assembling the special joint accessories. It can be used under high pressure and can be used with deflection.
Kubolock-T is restrained coupling. It can be simply assembled with T-type joint for restrained mechanism.
Kubolock-K is retainer gland. It can be simply assembled with K-type joint for restrained mechanism.
RF type is rigid joint. Generally, it is used to joint valves and other parts.
Jacking method is used to install a pipeline without trench excavation. Pipe is covered with reinforced concrete, which allows the pipe to be jacked directly into the ground without a pipe casing.
PN-typeDN300-DN1500 (12"- 60")
PN-type, earthquake resistant joint is used for trenchless method into the casing pipes, aging pipes. The diameter of casing pipes can be reduced because PN-type is designed to minimize the outside bell diameter.
