同心和偏心异径管的尺寸公差ASME B16.9

Dimensional Tolerances of Concentric and Eccentric Reducers ASME B16.9

除非另有说明，否则尺寸公差以毫米为单位，除非另有说明否则尺寸公差等于±。

Dimensional tolerances are in millimeters unless otherwise indicated and are equal ± except as noted.

注：MSS SP-43仅包括适用于ASME B36.19中规定的Schedule 5S和10S管道的不锈钢对焊配件以及适用于Schedule40S管道的短端。MSS SP-4 3中规定的尺寸和尺寸公差与NPS 1/2-NPS 24的ASME B16.9规范中的尺寸和公差基本相同。坡口处的外径除外。

Note..MSS SP-43 only covers stainless steel buttweld fittings made for use with Schedule 5S and 10S pipe and Stub Ends suitable for use with Schedule 40S pipe, as defined in ASME B36.19. The dimensions and dimensional tolerances defined in MSS SP-43 are substantially the same as those in ASME B16.9 specifications from NPS 1/2 - NPS 24. Except with regard to the outside diameter at the bevel.
