Detailed Information:

RatnaExports.com produces a wide range of APH Tubes from premium raw materials from reliable suppliers. We manufacture these Tubes using state-of-the-art equipment in compliance with national and international quality standards. We can offer various shapes, widths, thicknesses, and customised specifications for our APH Tubes to meet our customers at competitive prices.

APHs (APHs) are Shell and Tube Heat Exchangers designed to heat the air before it is introduced into the boilers or furnaces/kilns to burn the fuel. The primary function of an APH is to take heat from the flue gases that come from the boilers.

By reducing the amount of usable heat lost in the flue gas, the APH increases the boiler’s thermal efficiency by recovering heat from the flue gas. For the combustion of fuel, shell, and tube heat exchangers known as APHs (APH) are used to pre-heat the air supplied to boilers, furnaces, and kilns.

A primary objective of an APH is to gather waste heat from flue gases leaving the boiler. APH Tubes must also meet elongation, hardness, yield strength, and tensile strength requirements.

In addition to collecting waste heat from the fuel gases leaving the boiler, the main objective of the Air Pre Heater is to ensure that the Tubes satisfy the requirements for elongation, hardness, yield strength, and tensile strength of the tube seizures and needed steam volume.

Chemical, sugar, power, steel, cooling towers, superheaters, paper, and air heater industries regularly use our ERW Tubes in boiler construction and maintenance.

Testing our products is also a priority to ensure they meet or exceed industry standards. APH Tubes undergo several inspections, including third-party inspections, PMI inspections, raw material inspections, intergranular corrosion tests, pitting resistance tests, flaring/flattening tests, etc.

APH Tubes Pros

It is possible to extract the maximum amount of waste heat from flue gases using a two-pass design.
It captures waste heat from flue gases expelled from boilers, increasing boiler efficiency by 2% to 3%.
This system improves the boiler’s efficiency by warming up the fuel before it enters the boiler.
The payback period is shorter, so there is a quicker return on investment.
