Ukucubungula
Ipayipi le-A106 GR B NACE lizosetshenziswa izimo zensiza emuncu, lapho ukuvezwa kwe-hydrogen sulfide (H₂s) noma ezinye izinto ezilonakalisayo zikhona. I-Wovic Steel yenza amapayipi eNac Nace aklanyelwe ukuhlinzeka ngokumelana okuhlukile kokuqhekeka kwe-sulfide tracting (SSC) kanye nokuqhekeka okubangelwa yi-hydrogen (hic) ngaphansi kwengcindezi ephezulu, izindawo zokushisa eziphakeme. Lawa mapayipi ahlangabezana namazinga we-nace kanye nama-Mnu 0175 amazinga, aqinisekisa ukuthi alungele izinhlelo ezibucayi ezimbonini ezifana namafutha negesi, ukucubungula amakhemikhali, i-petrochemical, kanye nesizukulwane samakhemikhali.
Ukwakheka kwamakhemikhali
Ukwakheka kwamakhemikhali kwepayipi le-A106 GR B Nace kwenzelwe amandla nokuphikiswa kokugqwala, ikakhulukazi ezindaweni ezihlonishwayo zensiza.
| Isithako semvelo | Ama-min% | UMax% |
| I-Carbon (C) | 0.26 | 0.32 |
| IManganese (MN) | I-0.60 | 0.90 |
| Silicon (si) | 0.10 | 0.35 |
| Phosphorus (p) | - | 0.035 |
| Isibabule (s) | - | 0.035 |
| I-Copper (CU) | - | 0.40 |
| Nickel (NI) | - | 0.25 |
| Chromium (cr) | - | 0.30 |
| Molybdenum (mo) | - | 0.12 |
Lokwakheka kwenzelwe ukunikeza amandla ngenkathi kuqinisekisa ukuthi ipayipi limelana nezimo zensiza emuncu kanye nezimo ezilinganiselayo ze-acidic.
Izakhiwo zemishini
I-A106 GR B NACE PIP yakhelwe ukusebenza okuphezulu ezimweni ezimbi kakhulu, ukuhlinzeka ngamandla ashubile kanye nokuqhamuka ngaphansi kwengcindezi kanye nokushisa.
| Impahla | Thanda |
| Amandla Okuthela (σ₀₀.₂) | 205 MPA |
| Amandla we-Tensile (σb) | I-415-550 MPA |
| I-Elongation (El) | ≥ 20% |
| Ubunzima | ≤ 85 HRB |
| I-Impact Glounced | ≥ 20 j at -20 ° C |
Lezi zakhiwo zemishini ziqinisekisa ukuthi ipayipi le-NECE liyakwazi ukumelana nokuqhekeka nokucindezelwa ngaphansi kwezimo ezinzima njengokucindezela okukhulu, okushisa okuphezulu kanye nezindawo ezimuncu.
Ukuphikiswa kokuphikiswa (ukuhlolwa kwe-HIC & SSC)
I-A106 GR B NACE PIP yakhelwe ukubekezelela izimo zensiza emuncu, futhi ihlolwe ngokoqobo ukuqhekeka kwe-hydrogen (HIC) kanye ne-sulfide ukucindezela ukuqhekeka (i-SSC) ngokuhambisana namazinga ka Mnu 0175. Lezi zivivinyo zibalulekile ekuhlolweni kwamandla wepayipi lokwenza ezindaweni lapho i-hydrogen sulfide noma ezinye izivumelwano ze-acidic zikhona.
Hic (hydrogen kuncenge ukuqhekeka) ukuhlolwa)
Lolu vivinyo luhlola ukumelana kwepayipi emiqhekene ye-hydrogen-elenziwe nge-hydrogen eyenzeka lapho kuvezwa ezindaweni ezimuncu, njengalezo eziqukethe i-hydrogen sulfide (H₂s).
I-SSC (SULFIDE STRESTRING CRUPLIng) Ukuhlola
Lokhu kuhlola kuhlola amandla wepayipi lokumelana nokuqhekeka ngaphansi kwengcindezi lapho kuvezwa i-hydrogen sulfide. Kulingisa izimo ezitholakala ezindaweni ezihlonishwayo zensiza efana nezinsimu zamafutha negesi.
Zombili lezi zivivinyo ziqinisekisa ukuthi ipayipi le-A106 GR B NACE lihlangabezana nezidingo eziqinile zezimboni ezisebenza ezindaweni ezihlonishwayo, futhi insimbi iyamelana nokuqhekeka nezinye izindlela zokugqekeza.
Izakhiwo Ezibonakalayo
I-A106 GR B NACE Pipe inezakhiwo ezilandelayo ezibonakalayo eziqinisekisa ukuthi zenza ngokuthembekile ngaphansi kwamazinga okushisa asezingeni elibi kakhulu:
| Impahla | Thanda |
| Incekusana | 7.85 g / cm³ |
| Ukuvuselelwa okushisayo | 45.5 w / m · k |
| I-Elastic modulus | 200 gpa |
| I-coefficient of thermal expression | 11.5 x 10⁻⁶ / ° C |
| Ukumelana kagesi | 0.00000103 ω · m |
Lezi zakhiwo zivumela ipayipi ukuba lilondoloze ubuqotho bezinhlekelele ngisho nasezimweni ezimbi kakhulu nasekuhlukaneni kwezinga lokushisa.
Ukuhlola nokuhlola
I-Wovic Steel isebenzisa isethi ephelele yezindlela zokuhlola ukuqinisekisa ukuthi ipayipi ngalinye le-A106 GR B NACE lihlangana namazinga aphesheya kwekhwalithi nokusebenza. Lezi zivivinyo zifaka:
● Ukuhlolwa okubukwayo nokwangempela:Ukuqinisekisa amapayipi avumelana nokucaciswa kwezimboni.
● Ukuhlolwa kweHydrostatic:Kusetshenziselwe ukuhlola ikhono lepayipi lokumelana nengcindezi ephezulu yangaphakathi.
● Ukuhlolwa okungeyona eyonakalisayo (NDT):Amasu anjenge-Ultrasonic Testing (UT) kanye nokuhlolwa kwamanje kwangaphambi kwesikhathi (ect) asetshenziselwa ukubona iziphambeko zangaphakathi ngaphandle kokulimaza ipayipi.
● Ukuhlolwa kwe-Tensile, umthelela, kanye nokuhlola kanzima:Ukuhlola izakhiwo zemishini ngaphansi kwezimo ezahlukahlukene zokucindezela.
●Ukuhlolwa kokumelana ne-acid:Kubandakanya ukuhlolwa kwe-hic kanye ne-SSC, ngokwezindinganiso ze-MR 0175, ukuqinisekisa ukusebenza enkonzweni emuncu.
Ubuchwepheshe be-boblic bensimbi
Amakhono okwenziwa wensimbi wensimbi yensimbi ayakhiwe azungeze izikhungo zokukhiqiza ezisika-onqenqemeni nokuzibophezela okuqinile ekulawulweni kwekhwalithi. Ngeminyaka engu-19 yesimo sezimboni, i-Wovic Steel isebenza ngokukhiqiza amapayipi aphezulu we-nace ahlangabezana nezidingo zezindawo ezisebenzayo kakhulu ezisebenzayo.
●Ubuchwepheshe Bokukhiqiza Okuthuthukile:I-Wovic Steel isebenza izindawo zokukhiqiza zombuso ezihlanganisa ukukhiqiza amapayipi angenamthungo, ukwelashwa okushisa, kanye nezinqubo ezithuthukile zokuhlanganisa.
●Ukwenza ngokwezifiso:Ukunikeza izixazululo zangokwezifiso, kufaka phakathi amamaki ahlukene amapayipi, ubude, ukumboza, kanye nokwelashwa okushisa, i-womc yensimbi eyisihambi ipayipi le-nace kwizidingo ezithile zamakhasimende.
●Ukuthekelisa Okugcwele Umhlaba Wonke:Ngokuhlangenwe nakho kokuthumela kwamanye amazwe emazweni angaphezu kwekhulu, i-womelic iqinisekisa ukulethwa okuthembekile futhi okufika ngesikhathi kwamapayipi asezingeni eliphakeme emhlabeni jikelele.
