Overview
Steam and thermic-fluid lines in NCR process plants are still widely insulated with wool that sags, wets and loses thickness within a few years. Calcium silicate pipe sections are rigid, hold their dimensions under aluminium cladding and can be walked on without damage — which is why refineries, sugar and chemical plants specify them. Wedge Industries Limited makes them to bore at Faridabad from its CalSil650LD board grade, so NCR plants get a made-to-schedule section without import lead times.
The sections suit pharmaceutical and chemical plants in Bhiwadi and Bawal, textile and dyeing units in Faridabad and Ghaziabad, food plants in Kundli and Sonipat, and the hot-water and steam distribution of hospitals and hotels in Delhi, Gurugram and Noida.

Frequently asked questions
Which pipe sizes can you make?
Any bore from NB 15 upwards; large diameters are made as segmented lags. Send the pipe schedule and Wedge confirms section sizes.
Why use calcium silicate instead of mineral wool pipe sections?
Calcium silicate is rigid, does not sag or compress under cladding, tolerates foot traffic and keeps its thickness for the life of the line; wool is cheaper but loses performance when wetted or compressed.
What is the maximum temperature?
650°C for the CalSil650LD grade; higher-temperature grades are available on request.
Do you supply cladding and bands?
Yes. Aluminium or GI cladding, bands and W-CSP joint paste are supplied with the sections, and Wedge crews install across NCR.
What is the lead time for pipe sections in NCR?
Standard NB sizes are produced at Faridabad within a few days of order; large schedules are phased to the site programme.
