Qhov zoo thiab qhov tsis zoo ntawm Socket Weld fittings

TXOJ CAI

1. Cov yeeb nkab yuav tsum tsis txhob beveled rau kev npaj vuam.
2. Ib ntus tack welding tsis tas yuav tsum tau ua kom haum, vim hais tias nyob rau hauv lub hauv paus ntsiab lus qhov haum kom haum haum.
3. Lub vuam hlau tsis tuaj yeem nkag mus rau hauv qhov bore ntawm cov yeeb nkab.
4. Lawv tuaj yeem siv rau hauv qhov chaw ntawm threaded fittings, yog li qhov kev pheej hmoo ntawm kev xau yog me dua.
5. Kev siv hluav taws xob tsis zoo rau ntawm qhov chaw vuam; Yog li ntawd, qhov tseeb haum thiab vuam yog qhov tseem ceeb. Lub fillet weld tej zaum yuav raug tshuaj xyuas los ntawm kev soj ntsuam saum npoo, sib nqus particle (MP), los yog kua penetrant (PT) txoj kev kuaj.
6. Kev tsim kho cov nqi qis dua nrog pob tw-welded pob qij txha vim tsis muaj qhov yuav tsum tau ua kom haum thiab tshem tawm cov tshuab tshwj xeeb rau pob tw weld kawg.

TXOJ CAI

1. Lub vuam yuav tsum xyuas kom meej qhov sib txawv ntawm 1/16 nti (1.6 hli) ntawm cov yeeb nkab thiab lub xub pwg ntawm lub qhov (socket).
ASME B31.1 para. 127.3 Kev Npaj rau Vuam (E) Socket Weld Assembly hais tias:
Hauv kev sib dhos ntawm qhov sib koom ua ntej vuam, cov yeeb nkab lossis lub raj yuav tsum tau muab tso rau hauv lub qhov (socket) mus rau qhov tob tshaj plaws thiab tom qab ntawd tshem tawm kwv yees li 1/16 "(1.6 hli) deb ntawm kev sib cuag ntawm qhov kawg ntawm cov yeeb nkab thiab lub xub pwg ntawm lub qhov (socket).

2. Qhov sib txawv ntawm qhov sib txawv thiab cov crevices sab hauv tshuav nyob rau hauv lub qhov (socket) welded systems txhawb corrosion thiab ua rau lawv tsis haum rau corrosive los yog radioactive daim ntaub ntawv uas cov khoom buildup ntawm cov pob qij txha yuav ua rau kev khiav hauj lwm los yog txij nkawm teeb meem. Feem ntau xav tau pob tw welds hauv txhua qhov ntau thiab tsawg ntawm cov yeeb nkab nrog ua tiav weld nkag mus rau sab hauv ntawm cov kav dej.

3. Lub qhov (socket welding) tsis tuaj yeem lees txais rau UltraHigh Hydrostatic Pressure (UHP) hauv daim ntawv thov kev lag luam khoom noj vim lawv tsis tso cai rau kev nkag mus rau tag nrho thiab tawm hauv qhov sib tshooj thiab cov crevices uas nyuaj heev los ntxuav, tsim kom muaj cov xau virtual.
Lub hom phiaj rau kev tshem tawm hauv qab hauv qhov (Socket Weld) feem ntau yog los txo cov kev ntxhov siab ntawm cov hauv paus hniav uas tuaj yeem tshwm sim thaum lub sij hawm solidification ntawm cov hlau weld, thiab tso cai rau qhov sib txawv ntawm qhov sib txawv ntawm cov khoom sib txuas.
