steel-in-steel pipe

The use sphere of S-I-S system and application are vast, especially the most ideal under ground piping system to the transfer the high temperature and pressure and the low temperature liquid. The spec of the inner pipe, width of insulation and the outer are most safe and economically designed and produced by the operating conditions and environments conditions. Especially, in case that form a air between the inner pipe and the outer pipe to a vaccum to 1mBar, the moisture of the air is removed and rise the thermal efficiency, so not only reduce the energy but also reduce the period of construction as a method of direct sales, it is easy to construct, so we reduce the cost of construction differently You can reduce the cost of maintenance by additianally equiping the protection of corrosion and sensing of water leakage systems, and can design and manufacture all conditions following the engineering spec.
