ANSI/ASME B1.20.1-2013 通用的管螺纹(英制)

Pipe Threads, General Purpose (Inch)

ASME B1.20.1-2013 一般用途用管螺纹 (英制)

ASME?s widely-referenced B1.20.1 Standard on Pipe Threads, General Purpose, Inch covers dimensions and gaging of the world?s most common pipe threads: NPT, NPSC, NPTR, NPSM, and NPSL. This long awaited revision incorporates both subtle and substantive changes, including: Moving of the gaging point of reference of external threads in certain circumstances; A new acceptability section for instances of gaging disputes; A change to parameters, facilitating the calibration of working gages; Guidance for plated or coated pipe threads; Better explanatory language for the lay-user.

JIS B 0255 AMD 1:2008 统一螺纹极限量规(修改件1)

This translation has been made based on the Amendment to the origi- nal Japanese industrial Standard revised by the Minister of Economy, Trade and Industry through deliberations at the Japanese Industrial Standards Committee as the result of proposal for revision of Japanese Industrial Standard with the draft being attached, based on the provi- sion of Article 12 Clause 1 of the Industrial Standardization Law ap- plicable to the case of revision by the provision of Article 14. Consequently, JIS B 0255:1998 is partially replaced with this Amend- ment.

Limit gauges for unified screw threads (Amendment 1)

GSO ISO 263:2008 以英寸为单位测量的螺纹 直径范围为 0.6 至 6.0 英寸的螺纹、螺栓和螺母的总体规划和选择

This International Standard tabulates IS0 inch screw threads (except for pipe threads) having the basic profile for triangular screw threads specified in IS0 68, /SO general purpose screw threads - Basic profile. It comprises both a general plan of the IS0 inch screw threads and the IS0 inch screw threads for screws, bolts and nuts, the latter being a selection from the former. It contains sizes in the diameter range 0.06 to 6 in, comprising a number of series of diameter/pitch combinations, together with a system of thread designations. It remains for each industry to choose for itself, by means of selection among the screw threads of this International Standard, the diameter/pitch combinations appropriate to its own needs.

BS 1580-1:2007 统一标准螺纹.第1部分:直径1/4 in及更大的螺纹.要求

This part of BS 1580 specifies limits of sizes, and tolerances, for single-start, clearance-fit unified screw threads, in inch units, with nominal diameters in and above, having the ISO basic profile as specified in BS ISO 68-2:1998. The part of BS 1580 specifies the following unified thread series as follows: a) standard variable pitch series: • a coarse thread series (UNC) from 1/4 in to 4 in nominal diameter; • a fine thread series (UNF) from 1/4 in to 3/2 in nominal diameter; • an extra fine thread series (UNEF) from 1/4 in to 27/16 in nominal diameter; b) standard constant pitch series: • a 4-threads per inch series (4 UN) from 21/8 in to 6 in nominal diameter; • a 6-threads per inch series (6 UN) from 23/16 in to 6 in nominal diameter; • an 8-threads per inch series (8 UN) from 17/16 in to 6 in nominal diameter; • a 12-threads per inch series (12 UN) from 5/8 in to 6 in nominal diameter; • a 16-threads per inch series (16 UN) from 7/16 in to 6 in nominal diameter; • a 20-threads per inch series (20 UN) from 5/16 in to 3 in nominal diameter; • a 28-threads per inch series (28 UN) from 5/16 in to 3/2 in nominal diameter; • a 32-threads per inch series (32 UN) from 7/16 in to 1 in nominal diameter; c) a special thread series (UNS) with diameter/pitch combinations other than those specified for the standard series.

BS 1580-3:2007 统一标准螺纹.第3部分:直径小于1/4 in的螺纹.要求

This part of BS 1580 specifies limits of sizes, and tolerances, for single-start, clearance-fit unified screw threads, in inch units with diameters 1/4 below in. This part of BS 1580 specifies unified screw threads from Number 0 (0.060 in diameter) to Number 12 (0.216 in diameter), known as the “numbered sizes” in the following standard series: • a coarse thread (UNC) series; • a fine thread (UNF) series; • for Number 12 threads, an extra fine (UNEF) 32 threads per inch diameter/pitch combination. NOTE Unified screw threads below 1/4 in diameter for attachment purposes and for general use in the aircraft industry are specified in Annex A.

BS 84:2007 惠氏螺纹牙样的平行螺纹.要求

This British Standard specifies limits of sizes, and tolerances, for single start parallel screw threads of Whitworth form, for general engineering use. It is not applicable to threads for threaded pipe joints, screw threads associated with interference fits, such as those on the “metal ends” of studs and in the corresponding tapped holes, or to screw threads which are to be subjected to high temperatures. This standard specifies the following thread series: a) a coarse thread series, the British Standard Whitworth (B.S.W.) series, with nominal diameters in the range in to 6 in. b) a fine thread series, the British Standard fine (B.S.F.) series, with nominal diameters in the range in to 4 in. NOTE The tables of limits and tolerances for the B.S.F. series extend up to the 3 in size only, since nominal sizes above 3 in are rarely used. c) a supplementary selected thread (WHIT. S.) series with nominal diameters from in to 7 in. d) a truncated Whitworth form series (specified in Annex A). This British Standard specifies limits of sizes, and tolerances, of uncoated threads and also for metal coated threads (including threads coated with nickel, tin or zinc) with a thickness of coating of the order of 0.000 2 in. It is not applicable to heavily coated threads (i.e. threads with a coating thickness above 0.000 35 in). NOTE Supplementary information is given in Annex B, Annex C and Annex D.
