Signature Heat Insulation Cover · Visakhapatnam
Removable heat covers for Visakhapatnam steel, refinery and power shutdowns
Maintenance buyers on a Visakhapatnam turnaround put a removable cover back over hot pipes, valves, flanges and equipment shells once inspection is finished. Signature Heat Insulation Cover, model DSZHIC, is that cover. You order it by the square metre. The listing leaves working temperature, fabric, colour, coating, thickness and weight open, so the quotation carries the surface temperature and the area. We make the line in Ahmedabad and dispatch it to the site address.
What DSZHIC lists for a shutdown cover
One model sits in Insulation Cloths. You specify DSZHIC and the square metres the job needs. HSN 70191900 places the line in the glass-fibre goods heading. That heading does not name a face fabric or a coating, and the product page does not either. Darshan Safety Zone holds ISO 9001:2015 for the company quality system. The cover listing carries no separate product standard.

Narrow runs take the insulation tape
DSZHIC is the cover for a wider surface: a valve body, a flange, a pipe run or an equipment shell. Signature Insulation Tape, model DSZSFG0.6, is the wrap for a narrow run, a joint, or the finish beside the cover. The tape is silicone-coated fiberglass, gray, 0.6 mm, 25 mm wide by 20 m, 1 kg a roll, listed at 550 °C to 900 °C, and sold by the kilogram. That temperature belongs to the tape. The cover listing stays blank on °C.
Cover — DSZHIC
Pipes, valves, flanges and equipment shells. Quote the square metres. Fasteners, layers and a custom outline are unlisted, so the site insulation procedure decides how the cover is held.

25 mm wide, 20 m on the roll, 1 kg, sold by the kilogram. Use it where a cover is too wide for the run. Quote the kilograms on the same shutdown enquiry.

Shutdowns that put this cover back on
These are working industrial places in and around Visakhapatnam. We do not keep a counter in any of them, and naming the place is not a supply claim. Match DSZHIC to the body you are covering, then add tape only where the run is narrow.
| Place | Setting | Cover job | Start with |
|---|---|---|---|
| Ukkunagaram steel works | Integrated steel works at Ukkunagaram, Gajuwaka. | A shutdown opens steam and utility valves, flanges and equipment shells around the works. The cover goes back on those bodies by the square metre. | DSZHIC by the square metre |
| Malkapuram refinery | Fuel refinery in Visakhapatnam, with planned unit turnarounds. | Inspection lifts insulation off valves, flanges and equipment shells. The cover is ordered as the area of each body that goes back into service. | DSZHIC for the bodies on the turnaround list |
| Parawada thermal station | Coal-fired super thermal station at Parawada, 4 × 500 MW. | A unit overhaul exposes main-steam and feed-water valves and flanges. Send the square metres and the metal temperature, because the cover lists no working temperature. | DSZHIC, with the surface temperature on the enquiry |
| Palavalasa coastal station | 1,040 MW coal-fired station (2 × 520 MW) at Palavalasa, Pedagantyada, on the Bay of Bengal. | Steam-generator and auxiliary piping. Covers for valve bodies and equipment shells are quoted by the square metre and kept dry between outages. | DSZHIC, stored dry |
| Port oil terminal and LPG jetty | Outer-harbour oil tanker terminal for crude and petroleum products, plus an LPG berth. Pipelines run from the berths toward the refinery tanks. | Valve stations on those lines. The cover sits on the valve body and the equipment shell. The 25 mm tape finishes the narrow run beside it. | DSZHIC on the body, DSZSFG0.6 on the narrow run |
Fit it dry, and retire a damaged cover
On the job
Fit DSZHIC over a clean, dry surface. Close edges and joints the way the site insulation procedure requires, so heat does not leak through gaps.
Before refit
Check for tears, burn marks, worn edges or oil. A cover soaked in oil can smoke when the line heats. Retire a damaged cover.
Between outages
Store covers dry, away from oils and sharp edges, including at the Palavalasa station where the next outage may be months away.
What the quotation needs
Prices stay on the product cards. The quotation is where we confirm DSZHIC area, any DSZSFG0.6 kilograms, and dispatch from Ahmedabad.
Line 1
Model
DSZHIC. One cover is listed. Name it on the quotation.
Line 2
Square metres
The area the cover has to sit on. There is no length and width box on the product.
Line 3
What it covers
Pipe, valve, flange or equipment shell, and how many of each are on the shutdown list.
Line 4
Surface temperature
The metal temperature at the job. The cover listing has no °C figure, so this line is how we confirm the duty.
Line 5
Narrow runs
Kilograms of DSZSFG0.6 if joints and small-bore lines need the 25 mm tape as well.
Line 6
Site
Ukkunagaram, Malkapuram, Parawada, Palavalasa, the port, or another Visakhapatnam address.

Questions from shutdown buyers
Which heat insulation cover fits a Visakhapatnam shutdown valve?
Signature Heat Insulation Cover, model DSZHIC, in Insulation Cloths. It is the removable cover for hot pipes, valves, flanges and equipment shells. One model is listed, and it is sold by the square metre.
How do I order DSZHIC by the square metre?
Measure the surface the cover has to sit on and send that area with the quotation. The listing has no length box, no width box and no thickness. It is not a made-to-measure jacket, so a valve drawing does not create a custom size on this model.
What working temperature does DSZHIC list?
The cover listing is blank on temperature. Send the surface temperature with the enquiry and we confirm the duty on the quotation. The 550 °C to 900 °C band is listed on Signature Insulation Tape DSZSFG0.6, which is a separate product. Our guide on reading temperature ratings explains how to use a band when a product lists one.
When should the shutdown also order insulation tape?
Use the cover on the valve body, the flange face and the equipment shell. Use Signature Insulation Tape DSZSFG0.6 where the run is narrow: a joint, a small-bore line, or the finish beside the cover. The tape is silicone-coated fiberglass, gray, 0.6 mm, 25 mm wide by 20 m, 1 kg a roll, sold by the kilogram. It has its own product page.
Does DSZHIC come with Velcro, zippers or a set number of layers?
Those details are unlisted. Secure the cover the way your site insulation procedure requires. Company catalogues that mention industrial Velcro or high-temperature zippers describe other jacket work. They do not apply to this model.
What fabric, colour, coating, thickness and weight are published?
None of those fields are filled for DSZHIC. The customs heading is HSN 70191900, glass-fibre goods. That heading does not name the face fabric or a coating. We will not guess a colour, a thickness or a weight on the quotation.
How do we fit a cover and when do we take it out of service?
Fit it on a clean, dry surface and close the edges so heat does not leak at the joints. Before you refit it, look for tears, burn marks, worn edges or oil. Oil on a cover can smoke when the line heats up. Store covers dry, away from oils and sharp edges, and retire a damaged one.
Is the same model used at the steel works, the refinery and the power stations?
Yes. DSZHIC is the one cover. What changes is the square metres, the surface temperature you send, and the site: Ukkunagaram steel works, the Malkapuram refinery, the Parawada thermal station, the Palavalasa coastal station, or the port oil terminal and LPG jetty. We do not keep a different cover code for each plant.
Is there a Visakhapatnam counter or a shelf of covers?
We manufacture DSZHIC in Ahmedabad and dispatch from there. Ukkunagaram, Malkapuram, Parawada, Palavalasa and the port have no Darshan Safety Zone counter, dealer or shelf. The quotation confirms dispatch. This page does not state an arrival day.
What should a maintenance buyer send for the quotation?
Model DSZHIC, the square metres, whether the cover sits on a pipe, valve, flange or equipment shell, the surface temperature, and the site address. Add kilograms of DSZSFG0.6 if narrow runs need tape. Use the contact form when the area is still being measured.
