Notes:
1）當短型翻邊短節用于PN 50和PN 110(300和600級）的較大法蘭以及大于等于PN 150(900級）的大部分規格的法蘭時，或當長型翻邊短節用于PN 260和PN 420(1500和2500級）的較大法蘭時，為了避免法蘭可能影響焊接，或許需要增加筒體的長度。長度增加量由制造商與采購方雙方協商。
When the short type is used on the larger flanges with PN 50 and PN 110(300 and 600 LB) and on flanges with PN 150(900 LB) and above, or the long type is used on the larger flange with PN 260 and PN 420(1500 and 2500LB), the length of the cylinder may be added to be feasible the welding, the adding length shall be negotiated by manufacturer and purchaser.
2）當采用榫槽面和凹凸密封面 時，必須增加搭接邊的厚度。增加厚度應附加（不包括）在基本長度F上。
The thickness of joint shall be added if the TG and MFM contact surface of flange are used, and the adding thickness shall increase (not be in-cluded in) the base length F.
3) A型圓角半徑R與GB/T 9118.1-9118.2或ASME B16.5中的松套法蘭的圓角半徑相符合。B型的圓角半徑 R僅用于MSS SP 43標準中，其長度F為短型。
The radius of fillet R(type A) shall conform to the ones of loose flanges according to GB/T 9118.1-9118.2 or ASME B16.5. The radius of fillet R (type B) is only applied for the standards of MSS SP-43 with short length F.
4)搭接直徑G與ASME B16.5中表示的標準機加工面相符合。搭接邊的背面應進行機加工，使其與安裝表面一致。當采用環連接密封面時，使用ASME B16.5中給出的尺寸K。
The lap joint diameter G shall conform to the standard machined face indicated in ASME B16.5, and the back of joint shall be machined to conform to the surface of installation.When RJ used, the size K specified in ASME B 16.5 Shall apply.
5）搭接厚度t應不小于管子的公稱壁厚。
The minimum lap joint thickness t shall not be less than the nominal pipe wall thickness.
