Table 9.2.1-1 Testing Coverage試驗覆蓋
Type of Fitting Tested [Note (1)] 測試的管件類型 注[ (1)] |
Qualifies the Following If the Same Design Thickness Is Used 如果采用相同的設計厚度,則可以按以下進行覆蓋
|
Short radius elbow [Note (2)] 短半徑彎頭[注(2)] |
Short radius, long radius, reducing long radius, or 3D radius elbow 短半徑彎頭,長半徑彎頭或 3 倍彎曲半徑彎頭 |
Long radius elbow [Note (2)] 長半徑彎頭[注(2)] |
Long radius, reducing long radius, or 3D radius elbow 長半徑彎頭,縮徑彎頭或 3 倍彎曲半徑彎 頭 |
3D radius elbow [Note (2)] 3 倍彎曲半徑彎頭[注(2)] |
3D radius elbow 3 倍彎曲半徑彎頭 |
Straight tee 等徑三通 |
Straight or reducing tees of any reduction 等徑三通或異徑三通(支口任意變徑級別) |
Reducing tee 異徑三通 |
Reducing tees with the same or more reduction in outlet size 異徑三通(支口變徑級別相同或支 口縮徑級別增大) |
Straight cross 等徑四通 |
Straight or reducing crosses of any reduction 等徑四通或異徑四通(支口任意變徑級別) |
Reducing cross 異徑四通 |
Reducing crosses with the same or more reduction in outlet size 異徑四通(支口變徑級別相同或 支口縮徑級別增大) |
Cap 管帽 |
Caps of the same configuration 相同類型的管帽 |
Eccentric reducer [Note (3)] 偏心異徑管[注(3)] |
Eccentric or concentric reducers with the same or lesser included transition angle 偏心異徑管或 同心異徑管(相同的過渡角或較小的過渡角) |
Concentric reducer [Note (3)] 同心異徑管[注(3)] |
Concentric reducers with the same or lesser included transition angle [Note (4)] 同心異徑管 (相同的過渡角或較小的過渡角)[注(4)] |
Lap joint stub ends 翻邊 |
Lap joint stub ends are exempt from proof 翻邊不需要進行驗證性試驗 |
NOTES 注:
(1) Paragraph 9.4 applies to as-tested and qualified fittings. 第 9.4 段適用於經測試合格的配件。
(2) A test of any angle elbow covered in Tables 6.1-1 through 6.1-6 will qualify any other angle.A factory-made segment elbow that has a proof test on a geometrically similar 45-deg or 90-deg elbow need not be tested separately.表 6.1-1 至6.1-6 中所涉及的任何角度彎頭進行測試,可以覆蓋其他角度。工廠草莓福利视频的彎管,如果在幾何上相似的 45 度或 90 度彎管進行了驗證試驗,則不需要單獨再進行試驗。
(3) Straight conical (no tangent) and bell-shaped reducers are considered different design configurations and require separate testing. 直錐型異徑管(無切線)和鍾形異徑管被認為是不同的設計配置,需要單獨測試。
(4) “Transition angle” is defined as the angle of the conical section and is calculated as the [arc tan (difference of
diameters/twice the length)] for concentric reducers or [arc tan (difference of diameters/length)] for eccentric reducers.
“過渡角”定義為圓錐截麵的角度,計算為同心異徑管的[arc tan(直徑差/長度的兩倍))]或偏心異徑管的[arc tan (直徑差/長度)]。
Table 9.3.1-1 Test Factor, f, Determination試驗因子 f 測定

Test Factor, 試驗因子 f |
One 一次 |
1.10 |
Two 兩次 |
1.05 |
Three or more 三次及以上 |
1.0 |
GENERAL NOTE: Tolerances are equal plus and minus except as noted 通注:公差除注釋外為正負偏差。注:
(1) The inside diameter and the nominal wall thicknesses at ends are to be specified by the purchaser 端部內徑和公稱壁厚由采購方指定:
(2) A minimum wall thickness of 87.5% applies unless the purchaser specifies a different wall thickness tolerance. See Figure 8-1, Note (1)(a)除非采購方規定不同的壁厚公差,否則,使用 87.5%作為最小壁厚。見圖 8-1,注(1)(a);
(3) Out-of-round is the sum of absolute values of plus and minus tolerances 圓度為正偏差和負偏差絕對值之和;
(4) This tolerance may not apply in localized areas of formed fittings where increased wall thickness is required to meet design requirements of para. 2.2。在成型管件的局部,當需要增加壁厚以滿足 2.2 條的設計要求時,該項公差不可以使用。
(5) Unless otherwise specified by the purchaser, these tolerances apply to the nominal inside diameter, which equals the difference between the nominal outside diameter and twice the nominal wall thickness.除非采購方另有要求,這些公差適用於公稱內徑等於公稱外徑減兩倍公稱壁厚的場合;
(6) See Table 6.1-9 for limiting dimensions of outside diameter of barrel.見表 6.1-9 筒體外徑尺寸限定。
