This standard (HG 20592~20635-97) is formulated by revising the primary standard HGJ 44~76-91 as well as HG 20527-92 and HG 20529-92 by reference to ISO 7005-1 (1992), ANSI B16.5 and DIN standards. The new standard after revision includes the international current European and American systems and forms a set of standard in allusion to pipe flange, gasket and bolting which has intact contents and clear system and is suited for Chinese conditions and gears to the international conventions. The new standard will improve the current situations of standards in this field such as disordered system, poor matchability and obsolete contents.
Thereinto, HG 20592~20614-97 belongs to European system and is formulated by revising and combining HGJ 44~76-91, HG 20527-92, HG 20529-92 and HG 5001~5028-58. Compared with the former standard, the newly revised standard has the following changes:
1. Applicable to outside diameter of steel tube, extending to international current series (A) and domestic following series (B) from domestic following series;
2. Supplemented threaded flange and integral flange and cancelled flanging ring loose flange;
3. Adjusted the pressure class range of slip-on hubbed flange and slip-on-welding flange
Slip-on hubbed flange PN0.6~4.0MPa DN≤600mm
Slip-on-welding flange PN0.25~0.6MPa DN≤2000mm
PN1.0~2.5MPa DN≤600mm
4. Revised sealing face dimensions and flange technical conditions;
5. Increased material varieties such as cast steel material and low temperature steel forging;
6. The pressure-temperature table of stainless steel was revised on the basis of 1% yield strength;
7. Adapting to two sets of steel tube outside diameter series, and adjusted and supplemented the gasket dimension;
8. Supplemented rubber, synthetic rubber and non-asbestos rubber pressboards as well as modified (filled) polytetrafluoroethylene flat washer material; revised the asbestos rubber gasket standard as standard for flat washer made of various nonmetallic materials;
9. Increased bolting length matching for various flange joints;
10. Marked the pipe flanges with the standard No. in HG 20592.
HG 20615~20635-97 belongs to American system and its compilation principles are as follows:
1. Took ANSI B16.5 and B16.47 as reference standard for the part of pipe flange; the SI system of parameters and dimensions is based on ISO 7005-1 (1992) and ISO 7483 (1991);
2. Adopted the marking pressure class of ISO 7005-1 (1992) (cancelling Class 75 and Class 400) so that the pressure classes of pipe flanges in European system and American system will not be mixed up.
PN(MPa) Class
2.0 150
5.0 300
11.0 600
15.0 900
26.0 1,500
42.0 2,500
3. Restricted the applicable PN-DN range of threaded flange and loose flange:
Threaded flange PN2.0~5.0MPa DN15~150mm
Loose flange PN2.0~11.0MPa DN15~600mm
4. Incorporated welding neck-collar (ANSI B16.9 and MSS SP43) into loose flange standard;
5. Incorporated Series B large-diameter flange of in ANSI B16.47 (API 605), and cancelled Series A large-diameter flange;
6. Increased DN 550mm (PN 2.0~11.0MPa);
7. Two sealing face types, i.e., small male and female face and small tongue and groove face, were not listed;
8. Restricted the flange types applicable to ring-joint face (integral flange, welding neck flange, socket welding flange and flange cover);
9. Compiled the pressure-temperature table according to ISO 7005-1 (1992) and ANSI B16.5 (1988); the applicable pressures of 20# steel and 15CrMo were properly adjusted due to the difference of mechanical property at normal temperatures, and the corresponding material classification of 16Mn is Class 1.3;
10. Compiled gasket standard on the basis of ANSI B16.20 (1993) and B16.21 (1992);
11. Increased the table of bolting length matching various flange joints;
12. Determined standard system and standard constitution of the part of American system by reference to HG 20592~20614-97 (European system).
This standard was proposed and organized for preparation by the Equipment design technology center station of Ministry of Chemical Industry and the chemical process piping design technique center of Ministry of Chemical Industry.
Chief drafters of this standard: Ying Daoyan, Yu Jun and He Anliang.

前 言
本標準(HG 20592~20635—97)是在原標準HGJ 44~76—91,以及HG 20527—92、HG 20529—92標準的基礎上,參照ISO 7005—1(1992)標準和ANSI B16.5、DIN標準修訂而成的。修訂后的新標準包括國際通用的歐洲和美洲兩大體系,形成了一套內(nèi)容完整、體系清晰、適合國情,并與國際接軌的管法蘭、墊片、緊固件標準。修訂后的新標準將改變這一領域內(nèi)標準體系零亂、配套性差、內(nèi)容陳舊的現(xiàn)狀。
其中HG 20592~20614—97屬歐洲體系,是對HGJ 44~76—91、HG 20527—92、HG 20529—92、HG 5001~5028—58進行修訂、合并而成。新修訂的標準和前標準比較有如下改變:
1.適用鋼管外徑,由國內(nèi)沿用系列擴展到國際通用系列(A)和國內(nèi)沿用系列(B);
2.補充螺紋法蘭和整體法蘭,取消了翻邊環(huán)松套法蘭;
3.調(diào)整帶頸平焊法蘭和板式平焊法蘭的壓力等級范圍
帶頸平焊法蘭PN0.6~4.0MPa DN≤600mm
板式乎焊法蘭PN0.25~0.6MPa DN≤2000mm
PN1.0~2.5MPa DN≤600mm
4.修訂密封面尺寸及法蘭技術條件;
5.增加鑄鋼材料和低溫鋼鍛件等材料品種;
6.不銹鋼材料以1%屈服強度為基礎修訂壓力—溫度表;
7.適應兩套鋼管外徑系列,對墊片尺寸進行調(diào)整、補充;
8.補充橡膠、合成橡膠、非石棉橡膠壓制板、改性(填充)聚四氟乙烯等平墊片材料,將石棉橡膠板墊片標準修訂為包括各種非金屬材料的平墊片標準;
9.增加各種法蘭接頭配用的緊固件長度表;
10.管法蘭統(tǒng)一以HG 20592標準號標志。
HG 20615~20635—97屬美洲體系,其編制原則如下:
1.以ANSI B16.5、B16.47為管法蘭部分參照標準。參數(shù)、尺寸的SI制以ISO 7005—1(1992)、ISO 7483(1991)為依據(jù);
2.按ISO 7005—1(1992)標志壓力等級(取消了Class 75和Class 400),使歐洲、美洲兩大體系管法蘭的壓力等級互不混淆。

5.0 300
11.0 600
15.0 900
26.0 1500

3.限制螺紋法蘭和松套法蘭適用PN—DN范圍:
螺紋法蘭PN2.0~5.0MPa DN15~150mm
松套法蘭PN2.0~11.0MPa DN15~600mm
4.將對焊環(huán)(ANSI B16.9和MSS SP43)納入松套法蘭標準;
5.納入ANSI B16.47中B系列大直徑法蘭(API 605),取消了A系列大直徑法蘭;
6.增加DN550mm(PN2.0~11.0MPa);
7.未列入小凹凸面及小榫槽面兩種密封面型式;
8.限制了,環(huán)連接面適用的法蘭型式(整體法蘭、帶頸對焊法蘭、承插焊法蘭、法蘭蓋);
9.按ISO 7005—1(1992)和ANSI B16.5(1988)編制壓力—溫度表。20鋼、15CrMo由于常溫機械性能的不同,對適用壓力進行適當調(diào)整,16Mn對應1.3級材料分類;
10.以ANSI B16.20(1993)、B16.21(1992)為依據(jù)編制墊片標準;
11.增加各種法蘭接頭配用的緊固件長度表;
12.參照HG 20592~20614—97(歐洲體系)確定美洲體系部分的標準體系及標準組成。
本標準由化工部設備設計技術中心站和化工部化工工藝配管設計技術中心站提出并組織編制。
