Umehluko phakathi kwepayipi lensimbi elingenamthungo le-ASTM A53 nepayipi lensimbi elingenamthungo le-ASTM A106

Ububanzi be-ASTM A106 ne-ASTM A53:

Ukucaciswa kwe-ASTM A53 kuhlanganisa izinhlobo zokukhiqiza amapayipi ensimbi ngendlela engenamthungo futhi eshiselwe, impahla eyi-carbon steel, insimbi emnyama.Indawo engaphezulu yemvelo, emnyama, futhi eshisiwe, ipayipi lensimbi elihuqwe ngezinki.Ububanzi busuka ku-NPS 1⁄8 ukuya ku-NPS 26 (10.3mm ukuya ku-660mm), ukujiya kodonga okuzisholo.

Ukucaciswa okujwayelekile kwe-ASTM A106 kuhlanganisa i-ipayipi lensimbi engenamthungo, isicelo samasevisi wezinga lokushisa eliphezulu.

Izinhlobo ezihlukene kanye namabanga kukho kokubili okujwayelekile:

Ku-ASTM A53 kukhona i-ERW namapayipi ensimbi angenamthungo Uhlobo F, E, S amboza iBanga A no-B.

I-A53 Type F, i-furnace butt eshiselwe, iBanga A le-weld eqhubekayo

Uhlobo lwe-A53, olushiselwe ukumelana nogesi (ERW), eBangeni A naseBangeni B.

I-A53 Type S, ipayipi lensimbi engenamthungo, kuBanga A kanye neBanga B.

Uma impahla yensimbi eluhlaza yamabanga ahlukene isaqhubeka nokusakazwa, umphumela wento yoshintsho uzokhonjwa.Futhi umkhiqizi kufanele asuse okokusebenza kwenguquko ngezinqubo ezingahlukanisa amamaki kahle.

Uma kwenzeka i-ASTM A53 Grade B kupayipi le-ERW (elishiselwe ukumelana nogesi), i-weld seam kufanele yenziwe ukwelapha ukushisa okungenani okungu-1000°F [540°C].Ngale ndlela i-martensite engapheli ihlala.

Uma kwenzeka ipayipi le-ASTM A53 B emakhazeni linwetshiwe, ukunwetshwa akufanele kudlule u-1.5% we-OD edingekayo.

Okwepayipi lensimbi le-ASTM A106, ukukhiqiza Uhlobo olungenamthungo kuphela, lucubungula ukushisa okugoqiwe kanye nokubanda okudonswe.IBanga ku-A, B kanye no-C.

I-ASTM A106 Ibanga A: Ingxenye Ephezulu Yekhabhoni engu-0.25%, Mn 0.27-0.93%.Amandla amancane okudonsa 48000 Psi noma 330 Mpa, khiqiza amandla 30000 Psi noma 205 Mpa.

I-A106 Ibanga B: Isilinganiso esiphezulu C ngaphansi kuka-0.30%, Mn 0.29-1.06%.Amandla amancane okudonsa 60000 Psi noma 415 Mpa, khiqiza amandla 35000 Psi noma 240 Mpa.

IBanga C: Ubukhulu C 0.35%, Mn 0.29-1.06%.Amandla amancane okudonsa 70000 Psi noma 485 Mpa, khiqiza amandla 40000 Psi noma 275 Mpa.

Ngokuhlukile ngeI-ASTM A53 GR.B amapayipi ensimbi angenamthungo,I-ASTM A106 GR.B amapayipi ensimbi angenamthungoine-Si min 0.1%, i-A53 B ino-0, ngakho i-A106 B inokumelana nokushisa okungcono kune-A53 B, njengoba i-Si ithuthukisa ukumelana nokushisa.

Izindawo zohlelo lokusebenza zombili:

Womabili amapayipi afaka isicelo semishini kanye nezinhlelo zokucindezela, ukuthutha umusi, amanzi, igesi, nokunye.
