Natural Circulation Energy Saving Industrial Steam Boiler Parts Manifold Header
Product description
Headers form an important part of all types of boilers. Steam from the generating tubes is collected in headers which are therefore always under pressure. This pressure may vary from 300 psi to 2000 psi. Since headers are always under pressure, the utmost care is taken by us while fabricating them.The necking hinders of the Company are made by hot press and retracting of seamless steel pipes at special hinder necking machine. 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.
