ASME Carbon Steel Boiler Superheater And Reheater Coils

Superheater Coil Introduction

Superheaters and reheaters are specially designed to increase the temperature of the saturated steam and to help control the steam outlet temperature. They are simple single-phase heat exchangers with steam flowing inside and the flue gas passing outside, generally in the cross flow. Superheaters and reheaters are often divided into multiple sections to help control steam temperature and optimize heat recovery, and their heating surfaces can be arranged either horizontally or vertically. The physical design and location of the surfaces is dependent on the desired outlet temperature, heat absorption, fuel ash characteristics and cleaning equipment. The main components are usually manufactured from steel alloys, as both the superheater and reheaters are operated at high temperature.

The U-shaped tube heat exchanger has the largest heat exchange area; it has simple structure, compactness, high sealing performance, convenient maintenance and cleaning, minimum metal consumption under high temperature and high pressure, and the lowest cost; U-shaped tube heat exchanger has only one tube plate , Good thermal compensation performance and strong pressure bearing capacity, suitable for operation under high temperature and high pressure conditions. Energy conservation and environment protection.

*Note:HD BOILER can bespoke special type of economizer according to customer's requirement.

Test

1	Latest type of 'U' bending machine is used for precision cold bending of tubes.
2	Bending is done for all kind of heat exchanger, condenser, economizer, boiler tubes in Stainless Steel Seamless as well as welded.
3	Subsequent to 'U' bending tubes are hydro tested & stress relieved if asked for.
4	Also mock-up pieces are prepared for determining thickness reduction on the bend portion.
5	Dye penetrant testing on the bend portion is done ro detect cracks, flaws or any type of defect.
6	Special packing is provided to prevent any damages during transit.
