Industrial Steam Boiler Manifold Headers With Longitudinal Welded Pipe ASME Standard

Product Description

Boiler headers, or boiler manifolds are designed to simplify piping near the boiler, reduce installation time, labor costs and parts used. Available in various branch options with threaded inlet and outlet connections. For closed loop heating applications only.

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.

Technical Parameter

Test standard

JB/T3375 Boiler Material Instocking Acceptance Rules.

Product Category

The boiler headers have water wall header,superheater header,economizer header and so on. It acts action of gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders.

Construction

Header construction is basically a miniature version of a simple steam drum (diameters are smaller than the ones of steam drums). However, in headers there are usually no internals except the orifices in forced circulation and once-through principle boilers. Small diameter headers are constructed from a tube with welded front and end plates, whereas the big headers are made of bent steel plates in the same way as steam drums.

Quality Control

1. Impact test and Strength calculation report with applied materials information.

2. 100%NDT(non-destructive inspection) report of steel plate, tube and electrode.

3. X-ray, γ-ray and liquid penetrant test inspection report to ensure the quality of the entire boiler.

4. Hydraulic test report: ensure the standard working pressure and safety.
