1. 동판 및 경판의 두께는 표 5.5.15의 식에 의한 소요두께 이상이어야 하며, 지름, 압력, 온도, 재료 등을 고려하여 우리 선급이 특별히 승인한 경우를 제외하고 5 mm 이상이어야 한다. 다만, 모든 반구형 경판을 제외한 곡면경판의두께는 그 경판이 부착된 동판이 이음매 없는 경우일 때의 그 동판의 소요두께 이상이어야 한다.

2. 보강을 필요로 하는 구멍이 있는 경우의 경판의 소요두께는 다음 각호에 따른다.
(1) 구멍의 보강을 115.의 2항에 의한 경우에는 표 5.5.15에 따른다.
(2) 맨홀 또는 최대치수가 150 mm 를 넘는 구멍으로서 그 주위를 115.의 6항에 규정하는 플랜지형으로 보강하였을경우에는 다음에 따른다.

(가) 접시형 또는 반구형 경판 : 표 5.5.15에 따라서 산정된 값에 그의 15% (3 mm 미만의 경우에는 3 mm) 이상의 값을 더한 두께 이상으로 하여야 한다. 이 경우에 경판의 중앙부에 있어서의 안쪽반지름이 동체의 안지름의80% 미만인 경우에는 경판의 중앙부에 있어서의 안쪽반지름을 동체의 안지름의 80% 로 하여 계산하여야 한다. 또한, 두 개의 맨홀이 있는 경판의 두께를 이와같이 정하였을 경우에는 두 개의 맨홀사이의 거리가 경판 바깥지름의 1/4 이상이어야 한다.
(나) 반타원형 경판 : 표 5.5.15에 따라서 계산하되 이 경우의 R 은 동체의 안지름의 80% 로 하고, E는 1.77 로 한다.

(비고)
(1) 접시형 경판의 중앙부에 있어서의 안쪽반지름은 경판의 플랜지 부분의 바깥지름보다 커서는 아니 된다. 또한, 경판의 모서리에 있어서의 안쪽반지름은 경판의 플랜지 부분의 바깥지름의 6 % 또는 경판 두께의 3 배 중 큰 것 이상이어야 한다.
(2) 반타원형 경판의 안쪽에서의 짧은 반지름은 긴 반지름의 1/2 이상이어야 한다.
(3) 부식 예비두께는 소요두께의 1/6 또는 1 mm 중 작은 것으로 한다. 다만 부식성 액체 또는 가스를 저장하는 압력용기는 부식 예비두께를 증가시킬 수 있으며 부식성이 없는 액체 또는 가스를 저장하는 압력용기 또는 내식성 재료를 사용하는 압력용기는 부식 예비두께를 감소시킬 수 있다. (2021)

3. 볼록면에 압력을 받는 경판의 소요두께는 오목면에 압력을 받는 경우의 경판 소요두께 산정식에서 설계압력의 P 대신에 p 의 1.67 배의 값을 적용하여 산정한 두께 이상이어야 한다.

Notes: [SADDLE STANDARD DWG(pdf)]
　1. All dimensions are in inches unless noted otherwise
　2. All saddles in this size range must be fully designed. The dimensions shown are a starting place or to be used for estimating only!
　3. Assume that anchor bolts diameter is d - 0.125, where d is the diameter of the hole. Assume that slots for sliding saddle are 6 d long.
　4. N = Number of ribs
　5. n = Number of anchor bolts
