Chemical pipelines thiab li qub yog ib qho tseem ceeb ntawm kev tsim tshuaj lom neeg thiab kev sib txuas ntawm ntau yam khoom siv tshuaj. Yuav ua li cas 5 feem ntau li qub hauv cov kav dej tshuaj ua haujlwm? Lub hom phiaj tseem ceeb? Dab tsi yog cov kav dej thiab fittings li qub? (11 hom kav dej + 4 hom yeeb nkab fittings + 11 lub valve loj) Cov kav dej tshuaj, tag nrho cov khoom no tau ua tiav hauv ib tsab xov xwm!

Chemical pipes thiab fittings li qub

Cov yeeb nkab tshuaj yog cais los ntawm cov khoom siv: cov kav hlau thiab cov kav tsis yog hlau.

Hlau raj

Cam khwb cia hlau kav, seam steel kav, seamless steel kav, tooj liab kav, txhuas kav, thiab txhuas kav.

① Cam khwb cia hlau yeeb nkab:

cam khwb cia hlau yeeb nkab yog ib qho ntawm cov kav dej uas nquag siv hauv cov kav dej tshuaj.

Vim nws brittleness thiab tsis zoo kev twb kev txuas nruj nreem, nws tsuas yog haum rau conveying uas tsis tshua muaj siab media, thiab tsis haum rau conveying high-temperature thiab high-pressure chav thiab tshuaj lom thiab tawg. Feem ntau siv rau hauv cov kav dej hauv av, cov kav dej thiab cov kav dej phwj. Qhov tshwj xeeb ntawm cov kav hlau cam khwb cia yog qhia los ntawm Ф puab txoj kab uas hla × phab ntsa thickness (mm).

② Seamed steel yeeb nkab:

Seam steel kav tau muab faib ua cov kav dej zoo tib yam (siab tsis kam 0.1 ~ 1.0MPa) thiab cov kav dej tuab (siab tsis kam 1.0 ~ 0.5MPa) raws li lawv cov kev ua haujlwm siab.

Nws feem ntau yog siv los thauj cov kua dej xws li dej, roj, cua sov, cua compressed, thiab roj. Galvanized kav yog hu ua galvanized hlau kav los yog galvanized kav. Cov uas tsis yog galvanized yog hu ua cov kav hlau dub. Nws specifications qhia nyob rau hauv cov nqe lus ntawm nominal txoj kab uas hla. Qhov tsawg kawg nkaus nominal txoj kab uas hla yog 6 hli thiab qhov siab tshaj plaws nominal txoj kab uas hla yog 150 hli.

③ Seamless steel yeeb nkab:

Qhov zoo ntawm seamless steel yeeb nkab yog nws cov khoom zoo thiab lub zog siab.

Cov khoom siv yog carbon steel, high-quality steel, low-alloy steel, stainless hlau, thiab kub-resistant steel. Vim muaj ntau txoj kev tsim khoom, muaj ob hom: kub dov seamless steel kav thiab txias-draw seamless steel kav. Hauv kev tsim cov kav dej, cov kav dej kub-dov yog feem ntau siv thaum txoj kab uas hla tshaj 57mm, thiab cov kav dej txias yog feem ntau siv thaum txoj kab uas hla qis dua 57mm.

Seamless steel kav feem ntau siv los thauj txhua yam ntawm cov pa roj, vapors thiab kua, thiab tuaj yeem tiv taus qhov kub thiab txias (txog 435 ° C). Alloy steel kav yog siv los thauj cov xov xwm corrosive, ntawm cov kav hlau uas tiv taus cua sov tuaj yeem tiv taus qhov kub txog li 900-950 ℃. Qhov tshwj xeeb ntawm seamless steel yeeb nkab yog qhia los ntawm Ф puab txoj kab uas hla × phab ntsa thickness (mm).

Qhov siab tshaj plaws sab nraud ntawm cov yeeb nkab txias yog 200mm, thiab qhov siab tshaj plaws sab nraud ntawm cov yeeb nkab kub dov yog 630mm. Seamless steel kav tau muab faib ua cov kav dej seamless thiab tshwj xeeb seamless kav raws li lawv siv, xws li roj av tawg seamless kav, boiler seamless kav, thiab chiv seamless kav.

④ Copper yeeb nkab:

Lub raj tooj liab muaj qhov zoo ntawm cov cua sov.

Feem ntau yog siv rau hauv cov kav dej ntawm cov khoom siv hluav taws xob sib pauv thiab cov khoom siv cryogenic, ntsuas ntsuas ntsuas cov raj lossis xa cov kua dej, tab sis thaum qhov kub siab tshaj 250 ℃, nws tsis tsim nyog siv nyob rau hauv siab. Vim tias tus nqi kim dua, nws feem ntau yog siv rau hauv qhov chaw tseem ceeb.

⑤ Aluminium Tube:

Aluminium muaj zoo corrosion kuj.

Aluminium raj feem ntau yog siv los thauj cov xov xwm xws li concentrated sulfuric acid, acetic acid, hydrogen sulfide thiab carbon dioxide, thiab kuj tseem siv rau hauv cov khoom siv hluav taws xob. Aluminium tubes tsis muaj alkali-resistant thiab tsis tuaj yeem siv los thauj cov tshuaj alkaline thiab cov kev daws teeb meem uas muaj chloride ions.

Raws li cov neeg kho tshuab lub zog ntawm lub raj aluminium txo qis nrog qhov nce ntawm qhov kub thiab txias, kev siv kub ntawm lub raj txhuas tsis tuaj yeem tshaj 200 ° C, thiab kev siv kub yuav qis dua rau cov raj xa dej. Aluminium muaj cov khoom zoo dua qub ntawm qhov kub thiab txias, yog li txhuas thiab aluminium alloy raj feem ntau yog siv rau hauv cov khoom sib cais cua.

⑥ Cov kav dej:

Cov kav dej txhuas feem ntau yog siv los ua cov kav dej rau kev thauj cov kua qaub tawm. Lawv tuaj yeem thauj 0.5% -15% sulfuric acid, carbon dioxide, 60% hydrofluoric acid, thiab acetic acid nrog cov concentration tsawg dua 80%. Nws tsis haum rau thauj nitric acid, hypochlorous acid thiab lwm yam xov xwm. Qhov siab tshaj plaws ua haujlwm kub ntawm cov yeeb nkab txhuas yog 200 ℃.

Lub raj tsis yog xim hlau

Cov yeeb nkab yas, yas yeeb nkab, iav yeeb nkab, ceramic yeeb nkab, cement yeeb nkab.

①Cov yeeb nkab yas:

Qhov zoo ntawm cov kav dej yas yog zoo corrosion kuj, lub teeb yuag, yooj yim molding thiab ua tau yooj yim.

Qhov tsis zoo yog qhov tsis muaj zog thiab tsis muaj cua sov ua haujlwm.

Tam sim no, feem ntau siv cov kav dej yas yog cov kav dej tawv polyvinyl chloride, cov kav dej mos polyvinyl chloride, cov kav dej polyethylene,polypropylene kav, thiab cov kav hlau hlau nrog polyolefin thiab polychlorotrifluoroethylene txau rau ntawm qhov chaw.

② Roj Hmab Tube:

Lub raj roj hmab muaj qhov zoo tiv thaiv corrosion, lub teeb yuag, zoo plasticity, hloov tau yooj yim thiab yooj yim installation thiab disassembly.

Cov raj siv roj hmab feem ntau yog ua los ntawm cov roj hmab ntuj lossis cov roj hmab hluavtaws, thiab tsim nyog rau lub sijhawm uas yuav tsum tsis txhob siab.

③ Lub raj mis:

Lub iav raj muaj qhov zoo ntawm kev tiv thaiv corrosion, pob tshab, yooj yim tu, tsis muaj zog, thiab tus nqi qis. Qhov tsis zoo yog tias nws nkig thiab tsis tuaj yeem tiv taus siab.

Nws feem ntau yog siv rau hauv kev sim lossis kev sim ua haujlwm.

④ Ceramic tube:

Chemical ceramics zoo ib yam li iav thiab muaj corrosion kuj zoo. Ntxiv nrog rau hydrofluoric acid, fluorosilicic acid thiab muaj zog alkalis, lawv tuaj yeem tiv taus ntau yam inorganic acids, organic acids thiab organic solvents.

Vim nws tsis tshua muaj zog thiab brittleness, nws feem ntau yog siv los tshem tawm corrosive media hauv cov kav dej thiab cov kav dej.

⑤ Cement yeeb nkab:

Nws yog tsuas yog siv nyob rau hauv lub sij hawm uas lub siab yuav tsum tau thiab lub sealing ntawm kev twb kev txuas yeeb nkab tsis siab, xws li underground dej phwj thiab cov kav dej.
