Anxexure -VIII

Inspection of Steam Pipes 

(a) Steam pipes shall be inspected and hydraulically tested before erection in place, in test pressure to be that prescribed in the standard conditions for steam pipes. A certificate from the Inspecting Authority in Form III A, stating that this has been done by him may be accepted. If the Inspector is satisfied with the test, the pipes may be erected in position. The Chief Inspector shall intimate his approval to the owner regarding the suitability of the pipe line for use at the pressure and temperature to be specified. 

*(b) At subsequent inspections of the boiler or at any other time, the Inspector may make an external inspection of the steam-pipes and for this purpose may require a part of the lagging at the flanges to be removed, and the pipe made bare. If as a result of this inspection the inspector is of opinion that the pipes or any positions of then are in an unsatisfactory condition he shall report the matter to the Chief Inspector, who may require the whole of the lagging to be removed and may require any pipe or pipes to be hydraulically tested. The test pressure at such hydraulic test shall be not less than one and half times, the working pressure of the boiler of the intended working pressure of pipe as the case may be. 

*(c) A memorandum of Inspection Book shall be prepared in respect. of steam-pipe and fittings in Form No. XIV. In this book, the Inspector shall enter in ink all particulars and dimensions of the steam pipe and fitting with calculations for the various parts in detail, particulars of hydraulic test and his inspection notes. At subsequent inspection, the Inspector shall enter the date of the inspection and hydraulic test together with notes thereon. The Inspector shall also enter in the Memorandum of Inspection Book remarks regarding the general condition of the steam-pipes and fittings, and repairs, replacements of alterations, if any, and the extent to which the steam pipes have been cleaned of lagging and covering so that the book provides a useful record of the steam-pipes and fittings for the information and guidance of Inspectors at subsequent inspection. In the event of an accident to a pipe line or its fittings, necessary remarks shall also be entered in the book. The Memorandum Book shall be submitted to the Chief Inspector, who will check all particulars and calculations and approve the working pressure and temperatures that are to be permitted for the various parts of the pipe line and fittings. The pressure and temperature once approved for the particular steam pipe line shall not be altered except on a written authority from the Chief Inspector.

Submission of Plans of Steam-Pipes 

(a) Plans of steam pipes shall be submitted with the prescribed fee to the Chief Inspector before construction or at the time of the boiler for his decision whether the pipes and their arrangement comply with the Regulations. 

** (b) (i) The fees for examination of plans and the particulars of materials, design and construction of steam pipes before the commencement of manufacture of the steam pipes shall be at the rate of Rs. 30/- for 30 meters of piping or part thereof, subject to a minimum of Rs. 50, inclusive of all fittings excepting the fittings like de-super heaters, steam receivers, feed heaters and separately fired super heaters. For any fittings like de-super heaters, steam receivers, separators and flanges, the fees shall be Rs. 150.00 for each category of such identical fittings. 

(ii) The fees for examination of layout plans of steam pipes shall be Rs. 20/- per 30 meters of piping or part thereof, subject to a minimum of Rs. 50/- inclusive of all fittings, except fittings like de-super heaters, steam receivers, feed heaters and separately fired super heaters. For any fittings like de-super heaters, steam receivers and separators, the fee shall be Rs. 150.00 for each such fitting.
