Eco-friendly Energy Saving Industrial Steam Boiler Parts Manifold Header
General Description
In order to improve the efficiency of boilers, cylindrical boilers are gradually developed into tubular boilers to increase the heat transfer area.
The water from the pot barrel flows into the lower box through the downspout, which is distributed to each tube bundle. The water in these tube bundles continuously absorbs heat energy and collects in the upper box before flowing back into the pot barrel.
We call the upper and lower box box or header box.
Header (also known as header), is an important part of the boiler, divided into upper header and lower header.
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.
Parameter
| Material | Carbon steel,Alloy steel,Stainless steel. |
| Length | According to costumes requirements. |
| Temperature Range | 300℃~1500℃ |
| Diameter(OD) | 76mm~914mm |
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.
