Red Effective Energy Saving Boiler Manifold Headers For Industry , Long Life

Product Introduction

In order to improve the efficiency of the boiler, tubular boilers are gradually developed into tubular boilers to increase the heat transfer area. The pot water flows from the pot barrel to the lower box through the downward tube, and is distributed to each tube bundle by the box body. The water in these tube bundles continuously absorbs heat energy and collects into the upper box body and then flows back into the pot barrel. We call the upper and lower boxes header or header. Header (also known as header) is an important part of the boiler, which is divided into upper header and lower header.

Functions

Header is a pipe fittings for mixing working substances of boilers and ensuring uniform heating of working substances. Usually, the furnace wall of industrial boiler is composed of rows of tubes (water wall). But the boiler is huge and complex in structure. It can not guarantee that all the working substances in the tubes absorb the same heat. There are many differences in heat absorption in different parts. Installation of header can let the working substances in each tube converge here and distribute to the next level of each tube. Samples can reduce thermal deviation, so that refrigerant heat absorption, flow, boiler cooling, boiler thermal efficiency have been optimized and improved; in addition, the size, number and layout of pipes in the upper, middle and lower parts of the boiler are different, header is responsible for connecting each section to ensure smooth flow of refrigerant.

Features

• The pressures and temperatures that headers have to withstand depend on the component to which they are connected. A header connected to an economizer or to water wall panels is subject to less severe requirements on the material than a header connected to superheaters or reheaters.
• Depending on the temperature and pressure of headers, Vallourec supplies tubes in carbon steel to high-alloy ferritic steels such as T/P91 or T/P92, with sizes ranging from 88.9 mm to 406.4 mm.

Details

1.The necking hinders of the Company are made by hot press and retracting of seamless steel pipes at special hinder necking machine.

2.In this way, the hinders will have thicker walls and cleaner surface. The necking cover will form membrane stress rather than bending stress with desired stress performance under the effect of inner pressure.
