Historic Machinery Services provides boiler restoration and repair. Although Historic Machinery is not a holder of an R stamp, our boiler work is perfomed following the NBIC (National Board Inspection Code)for repairs and the ASME (American Society of Mechanical Engineers) for new work and designs. Boiler survey's, to determine the MAWP, are performed by us, with the calculation and design aspect usually done or reviewed by an R and S stamp holder with which we have 23 years' association. This provides an independent review of the boiler's condition by a third, neutral party. Whether repair is riveted or welded, or alterations required, Historic Machinery has the experience, capacity and resources to perform not only tradional, but modern repair techniques.
