Double H Fin Tube Carbon Steel Economizer First class product Petroleum Economizer Natural Gas Industry
Description
1.Petroleum Economizer Natural Gas Industry can be made of alloy steel, carbon steel or other kind of material as per the customer’s requirements. It conforms to the standard of ASTM, EN, DIN, GB.
2.The manufacturing equipment is 30~185MN hydraulic press, the forging ratio >3, the technical condition is in accordance with the standard of ASTM, EN, DIN, GB.
Hot-rolled steel plate produce
1.Hot-rolled plate, hot-rolled steel plate.
2.Complete raw materials after the formation of smelting steel ingot, through the press forming process of ingot steel rolling heating.
3.Width is larger than 600mm(≥600mm), thickness is 0.35-200mm.
Applications
The main Petroleum Economizer Natural Gas Industry is Widely used for power plant, power station, etc.
Introduction
1.Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2.H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
3.With straight channel to gain the best ash-blowing effect.The compact structure to reduce the weight and reduce the manufacturing cost.
4.Hot rolled seamless steel tubes and cold rolled seamless steel tubes for steam boiler systems
5.Implementation of the same standard, medium and low pressure boiler tube standards can be used. Hot rolled or cold-rolled (drawn) seamless steel tubes with high quality carbon structural steel.
6.The 2 main 10, 20 steel manufacturing, in addition to ensure the chemical composition and mechanical properties of things do pressure test, curling, flaring and flattening test.
7.Hot rolling in hot rolling, cold rolling (DIAL) in heat treatment delivery.

Features
1.Because the spiral finned province coal equipment has high heat intensity per unit length, compact structure, material saving, wear and corrosion resistance, prevent ash performance is good, safe operation cycle is long, maintenance costs, high running economy etc.
2.So both boiler economizer replace the generation of a structure, promoting technical progress, a new type of heating equipment, energy saving and emission reduction is worth popularizing vigorously .
