(b) It is not permissible to build up or reinforce a grooved or corroded area of unstayed internal surfaces by means of welding, except that widely scattered pit holes may be built up by welding. (c) Where external corrosion has reduced the thickness of flat plates around hand holes to an extent of not more than 40 percent of the original thickness and for a distance not exceeding 2 inches from the edge of the hole, the plate may be built up by welding. (d) Where stayed sheets have corroded to a depth not exceeding 40 percent of their original thickness, they may be reinforced or built up by welding. Where the staybolts are fitted with riveted heads, the staybolts in the reinforced area must be renewed, but where the staybolts are fitted with nuts, the nuts may be removed and after reinforcing has been applied; collars may be welded around the staybolts in lieu of the nuts. Such reinforced areas must not exceed 400 square inches nor more than 30 inches in one direction. Two such areas in any one plate may be reinforced provided that the distance between the reinforced surfaces is not less than 30 inches.

Such rivets or staybolts must be replaced. The seal welding of rivet heads to secure tightness is prohibited. (b) Where leaks develop around staybolts which are otherwise in good condition, the nuts may be replaced with a beveled collar formed around the end of the stay by means of welding. In such cases, the depth of collar measured on the stay and the width measured on the plate, must be equal to one-half the diameter of the staybolt. | ||||

Such plates must have a diameter of at least 2 inches larger than the diameter of the hole and must have a thickness equal to the thickness of the plate to which it is attached. It is not permissible to insert such patches in the shell or head flush with the surrounding plate unless the requirements of this subchapter for Class I welded pressure vessels are met.

If welding is employed on a line of staybolts, the staybolts must be fitted with a welded collar. (b) The edges of wrapper plates riveted to tube sheets and back heads must be removed by cutting out the rivets. (c) The edges of existing plates and new plates must be beveled by chipping, flame cutting or grinding so as to form a suitable groove whereby complete penetration of the weld metal will be obtained. The edge preparation and preheat must comply with the requirements of § 59.10-5(h). (d) The edges of the new plate must be butt-welded, and the plate must be riveted to the flanges of the tube sheet and back heads and the staybolts renewed. (e) Sections of wrapper plates of combustion chambers outside of stayed areas may be repaired by welding provided the welded joints are stress-relieved by means of controlled heat and the joints are nondestructively tested. | ||||
| 46:46:2.0.1.2.16.3.1.1 | 46 | Shipping | I | F | 59 | PART 59—REPAIRS TO BOILERS, PRESSURE VESSELS, AND APPURTENANCES | 59.15 | Subpart 59.15—Miscellaneous Boiler Repairs | § 59.15-1 Furnace repairs. | USCG | (a) Where corrugated or plain furnaces or flues are distorted by 1.5 inches or more, they must be repaired by either of the following methods: (1) The furnace must be forced back to a true circular shape, and the Officer in Charge, Marine Inspection, may require strongbacks or other acceptable means of support to hold the furnace; or (2) The furnace must be adequately stayed as determined by the Officer in Charge, Marine Inspection. (b) Distortion means the difference between any single measured diameter of the furnace and the diameter of a true circle at the same location. (c) Where the distortion does not exceed 1.5 inches it will not be necessary to force the furnace back to a true circle if the allowable pressure is reduced in the ratio of 1.5 percent for each one-tenth of an inch of distortion. However, if the maximum distortion does not exceed 1 inch, the repairs or reduction in pressure will not be required unless considered necessary by the marine inspector. (d) When it becomes necessary to rivet a patch to a furnace or other part of the heating surface, the riveted patch must be placed on the waterside of the plate in order not to form a pocket in which sediment may collect. (e) Furnace crowns which have become distorted, not in excess of the limitations provided in paragraph (c) of this section, may be repaired by forcing back the distorted section to as nearly a true circle as possible and reinforcing the same by means of a ring, arc- or gas-welded to the distorted corrugation as shown in figure 1 to § 59.15-1, the welding to be done by welders and welding processors qualified in accordance with part 57 of this subchapter. | ||||

(b) Where it is desired to rivet a patch to the wall of a stayed furnace or combustion chamber, the defective portion of the plate must be cut away until solid material is reached, the patch must be riveted on the waterside, and the staybolts renewed, and extended through the new plate. | ||||

(b) Where the shell plate is bagged due to overheating, the Officer in Charge, Marine Inspection, may, if in their judgment it is practicable, permit the same to be driven back to its original position. (c) Where the shell plate has blistered, bagged, or bulged to such an extent that there is an appreciable thinning of the plate, the Officer in Charge, Marine Inspection, must require the defective portion to be cut away and the shell repaired by fitting a patch of steel plate conforming to the requirements of § 52.01-90 of this subchapter in place of the defective portion. Care must be taken that the riveting schedule of the patch is so arranged as to give the plate sufficient strength to withstand the stress placed on it in service. | ||||
