PPGI/PPGL(prepainted galvanized steel /prepainted galvalume steel )is also known as pre-coated steel,color coated steel, coil coated steel, color coated steel,pre pianted steel sheet,The PPGI steel coil/sheet made of cold-rolled steel sheet and galvanized steel sheet, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner, and baked and cooled to form a product. Coated steel has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.
Color coated steel coil is mainly divided into three parts: construction, household appliances and transportation. Building is generally used to build the roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport,warehouse and freezer. Household appliances are used in the production of refrigerators and large air conditioning systems, freezers, toasters, furniture, etc. Transportation industry is mainly used for oil pan, automobile interior parts, etc.
PPGI is a product made of cold-rolled steel coil and (aluminum) Galvanized Steel Coil after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials.

Boiler energy-saving transformation parts h-fin tube with ASMEÂ
Specification:
Boiler energy-saving transformation parts h-fin tube with ASME . Boiler pressure replacement parts finned tube with ASME standard designed for use in natural and forced convection space heating, our range of finned air heaters are suitable for increased heat transfer surface area and where higher wattage is required. Featuring rugged construction, these finned heaters can be used in a multitude of industrial environments. Finned tubular heaters are used for forced convection heating, air or gas heating systems. Finned tubular heaters/heating elements are customized to meet your specific application needs.This is the introduction about Boiler pressure replacement parts finned tube with ASME standard. This is the introduction about Boiler energy-saving transformation parts h-fin tube with ASME .
Introduction:
Â
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). HÂ type fin tube can be made to double HÂ type fin tube, high rigidness to fit long tube row.
3). HÂ type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4). With straight channel to gain the best ash-blowing effect.
5). The compact structure to reduce the weight and reduce the manufacturing cost.

Application:
 In boilers, Economical low installation costs better performance boiler economizer for CFB boiler are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economical boiler economizers are so named because boiler economizers for water heating can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. Better performance boiler economizers are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
