Product Description

 

Steam distribution headers are fabricated out of carbon steel or alloy steel seamless tubes. Customised or tailor made items are offered. Headers, after fabrication, are stress relieved to make the Steam distribution headers free from stresses.They are big pipe headers that transfer water from the downcomers to the risers through a combustion zone where the water gets partially heated to steam from the heat of fuel combustion.

 

The key to the manufacture of the header is the welding of the end cap (or head). When welding, most manufacturers use manual arc welding, because the weld is single-sided welding, the root quality is difficult to guarantee, and because of the huge of welding work, number of repairing times, the production cycle is long which cause the entire production process slow. Our company adopt the advanced production technology, well-equipped instrument and sophisticated technology, and invented a submerged arc welding method during the header and cover welding. The character is: In the submerged arc welding machine head threading mechanism fixed connection welding wire guide, along the wire guide head to set the wire guide hole, the wire lead head has a certain degree of curvature, welding the inner wall, the wire guide head extension Into the inside of the welding. The welding method mainly solves the problem that the existing welding method of the boiler header and the end cap (or the head) has the advantages of low processing efficiency, waste of argon at the time of processing, need to open the groove, have many processes, high processing cost and unsatisfactory welding fabrication.

 

Operation

 

In bringing a boiler on the line with other boilers on a header system,certain precautionss are necessary to avoid water hammer and excessive temperature gradients in the piping.Adequate drainage and warming of the piping will eliminate the risk of water hammer.The judicious use of bypass valves around main header valves will avoid steep temperature gradients.Header drains should be operated.The steam line from the boiler to the header should be brought up to temperature by operationg bypass and drain valves.When up to temperature and line pressure,the header valve may be opened wide and the bypass closed.
