Yeeb Nkab lub cev roj pipeline

Niaj hnub no nws yog ib qhov nyuaj rau xav txog tej yam lub ntiaj teb no thiab lawv tus kheej lub neej tsis muaj tus ua tau ntawm science thiab technology. Muaj coob tus ntseeg hais tias lub ntsiab tau yog txoj kev loj hlob ntawm cov ntaub ntawv. Tab sis cia li xav txog tej yam koj lub neej tsis muaj muaj chaw! Nyob rau hauv txhua txhua hnub lub neej, tag nrho cov txaus siab rau cov kev pab cuam ntawm kev vam meej: dej, hluav taws xob, gas, cua sov - thiab yuav tsis xav txog tej yam ib tug nyiam lub neej tsis tau lawv. Nyob rau hauv thiaj li yuav xa dej thiab nkev, dej thiab nkev pipelines yog tab tom ua mus ua hauj lwm raws li lub tsheb.

Thaum mounting builders siv rau roj mains kav. Nws yog ib qho tseem ceeb yuav tau nco ntsoov hais tias lawv yog ib feem ntawm peb lub neej txhua hnub thiab nyob ib qho tseem ceeb rau txoj hauj lwm raws li ib tug uas tsis muaj nqi txhais tau tias tus me nyuam ntawm haus dej thiab roj cua.

Yuav ua li cas yog ib cov yeeb nkab?

Thaum lub caij, muaj yog tsis muaj ib qho lus teb rau lo lus nug no. Nyob rau hauv kev peb yuav hais tias cov yeeb nkab - nws yog ib tsab xov xwm uas siv hollow profile, uas yog siv rau cov thauj ntawm nkev, roj, ntau yam kua, rwb thaiv tsev, qhov cuab lub zog.

kev faib ntawm cov kav dej

Seamless kav yog mus dov (kub thiab txias ntxuag), nias (inch 820 hli) thiab cam khwb cia (hlau thiab hlau, txoj kab uas hla 900 hli).

Nyob rau hauv profile seem txawv daim, puag ncig:

• Square.

• lub.

• Oval.

• Ya.

• ribbed.

• teardrop-puab.

• six-, peb- thiab octagonal.

txawv los ntawm longitudinal seem:

• tapered.

• tshaj nrog chim siab xaus.

Qhov no tsis yog tag nrho daim ntawv teev cov hlab uas txawv nyob rau hauv lub longitudinal dav hlau. Nyob rau hauv ib tug nyias muaj nyias ib pab pawg neeg yog bimetallic, trimetallic, muaj raws ntawm ob peb hlau khaubncaws sab nraud povtseg, uas yog kev cob cog rua ua ke los ntawm welding, fusing los yog cog.

Kev siv ntawm seamless kav

Nyob rau lub hauv paus ntawm lub sij hawm yog muaj rau:

• roj thiab cov nkev kev lag luam;

• siv cov kev faib;

• piping;

• Mechanical Engineering;

• hlab ntsha thiab tso tsheb hlau luam.

Kav rau roj thiab cov nkev kev lag luam ua los ntawm cov pa roj carbon thiab hlau steels. Laum yeeb nkab yog siv rau zoo drilling thiab ua hauj lwm zoo txawj ntse. Casings yog siv rau kev tiv thaiv ntawm cov phab ntsa ntawm roj, roj zoo xeb ingress ntawm kua sib cais los ntawm txhua lwm yam thiab roj reservoirs. Kav rau pipelines siv rau qhov tus me nyuam ntawm nkev, roj, roj av, dej, acids. Tubing siv nyob rau hauv drilling qhov dej lag luam thaum lub roj ntau lawm yuav siv sij hawm qhov chaw, thiab tau threaded sib txuas. Boiler hlab siv nyob rau hauv boilers ntawm ntau yam designs. ntsiab yeeb nkab yog manufactured nyob rau hauv raws li GOST 3262-75 thiab yog welded. Yeeb Nkab siv raws li GOST 800-78, 8642-68 yog siv nyob rau hauv qhov siv thiab ua ntau yam tshuab qhov chaw nyob rau hauv aircraft engineering, cov tsheb laij teb. Kav ntes, nyob rau hauv raws li cov GOST 550-75, ua los ntawm steel 10, 20, K5M, K5 12MH thiab lwm leej lwm tus thiab yog siv los mus twj kub siab roj.

yeeb nkab Lub cev

Lub ntsiab feature ntawm lub koob qhia hais tias cov yeeb nkab inch yog loj, vim lawv yog siv rau mounting ntau yam lug nyob rau hauv lub tsev, kev mus los rau roj, roj av, chav, roj, roj thiab dej.

Lub cev steel yeeb nkab thiab muab kauv-welded manufactured, txoj kab uas hla 529-2560 hli thiab ib lub phab ntsa thickness ntawm 8-25 hli. Kav rau roj mains no yog ua los mus ua hauj lwm nyob rau hauv corrosive npuas, thaum tsa tau siab thiab nyob rau hauv nyuaj climatic tej yam kev mob. Yog li, qhov chaw ntawm lub ntsiab qhov chaw ntawm cov roj thiab roj nyob rau hauv Russia lub North yuav tsum tsim kho ntawm haib lub cev pipelines nyob underground.

Nyuaj climatic tej yam kev mob kom tsis tshua muaj neeg siab xav tau nyob rau hauv qhov zoo tshaj ntawm cov kav dej thiab lawv ua hauj lwm zoo zog - lub dag lub zog thiab plasticity yam ntxwv. Tej zaum cov pa roj yeeb nkab lub cev muaj ib tug tshwj xeeb txheej: puas, zinc, bituminous.

National Association ntawm Corrosion Engineers (NACE) tau tsim ib tug standard uas regulates lub xeem thiab cov tswv yim rau cov khoom uas yog resistant rau ntub hydrogen sulfide tej kev kawm. Kev Cai ntsuam xyuas tus ntsuam ntawm cov khoom: lub sij hawm mus ua hauj lwm thiab cov chaw pib voltage.

Rau lub raj cov ntaub ntawv uas, uas yog siv nyob rau hauv mob loj heev climatic tej yam kev mob, nws yog ib qho tseem ceeb thawj ntawm kub uas brittleness ntawm cov hlau tshwm sim, kev txhim kho nws cov khov zog, uas yog txiav txim rau lub nrws nrog ib tug yeej incision nrog ib tug tsawg kawg nkaus kub ntawm -60 ° C thiab rau tus nqi qis tau kuaj nrog ntse thais kev khiav hauj lwm kub -20 ° C. Uas yog vim li cas thiaj li tseem ceeb rau siv cov ntsiab kav ua rau GOST los yog TU.

Qaum raj: Standard thiab Specifications

Paub qhov txawv tseem ceeb yeeb nkab los ntawm:

1. Txoj kev vuam:

• Kuj welding.

• Arc welding.

2. Hom weld:

• Muab Kauv.

• longitudinally welded.

3. Lub hom phiaj:

• Kav rau lub ntsiab pipelines.

• Kav rau roj mains.

• kav rau lub cev pipelines nrog lwm yam xov xwm.

4. Inch:

• kav ntawm loj inch.

• kav me me txoj kab uas hla.

Nws yog ib qho tseem ceeb yuav tau nco ntsoov hais tias tus arc vuam - ib tug universal txoj kev, thiab cov kev sib cuag hom vuam yog tsuas yog siv rau cov ntsiab yeeb nkab nrog ib tug me me txoj kab uas hla. Yeeb Nkab roj pipeline systems loj inch yog tortsovannoy, nrog burrs raug muab tshem tawm. Yog hais tias cov yeeb nkab yog tsis tortsovannaya, burrs tsis muab tshem tawm nyob rau hauv lub Hoobkas.

GOST 20295-85 - yog qhov tseem ceeb ntxawg daim ntawv rau ntawm lub ntsiab kav.

Cov yeeb nkab lub cev: Tag Huv Tibsi

Raws li teb rau zus tau tej cov ib tug yeeb nkab steel qaum sawb steel siv, cov khoom uas protrude heev alloyed carbon (nyob ntsiag to, semi-tua) steel thiab tsawg hlau steel kub dov.

Steels siv rau zus tau tej cov ntsiab yeeb nkab:

• 10;
• 20;
• 09GSF;
• 10G2FBYU.

Yeeb Nkab qaum electrically GOST 20295-85, TU 14-3-1573-96:

Raws li yuav pom, lub ntsiab yeeb nkab siv nyob rau hauv txoj geological thiab climatic tej yam kev mob, corrosive tej kev kawm thiab yog manufactured raws li GOST thiab TU, ib tug loj assortment tsuas ntxiv dag zog rau txoj hauj lwm ntawm cov lwm yam ntsiab yeeb nkab hlau dov.
