1. Kev tsim thiab kev tsim cov yeeb nkab steel seamless tuaj yeem muab faib ua cov kav dej kub dov, cov kav dej txias, cov kav dej txias, cov kav dej extruded, thiab lwm yam raws li cov txheej txheem ntau lawm.

1.1. Kub dov seamless kav feem ntau yog tsim los ntawm cov yeeb nkab tsis siv neeg dov. Cov khoom siv lub raj tsis muaj raug tshuaj xyuas thiab qhov chaw tsis xws luag raug tshem tawm, txiav rau hauv qhov ntev uas yuav tsum tau ua, nyob rau ntawm qhov kawg ntawm lub raj perforated, thiab tom qab ntawd xa mus rau lub qhov cub cua sov rau cua sov thiab tho rau ntawm lub tshuab xuas nrig ntaus. Nws txuas ntxiv tig thiab nce mus thaum lub qhov tho qhov. Nyob rau hauv kev cuam tshuam ntawm cov chais thiab qhov kawg, lub raj khoob yog hollow maj mam, uas yog hu ua tag nrho cov yeeb nkab. Tom qab ntawd nws raug xa mus rau lub tshuab tsis siv neeg cov yeeb nkab dov mus txuas ntxiv dov. Thaum kawg, phab ntsa thickness yog evened los ntawm lub tshuab leveling, thiab txoj kab uas hla yog txiav txim los ntawm lub sizing tshuab kom tau raws li specification yuav tsum tau. Kev siv cov yeeb nkab txuas txuas ntxiv los tsim cov kav dej kub dov seamless steel yeeb nkab yog ib txoj hauv kev zoo dua.

1.2. Yog tias koj xav tau cov kav dej seamless nrog qhov ntau thiab tsawg thiab zoo dua, koj yuav tsum siv cov khoom siv txias txias, kos duab txias, los yog ua ke ntawm ob. Txias dov feem ntau yog ua los ntawm ob-yob zeb, thiab cov yeeb nkab steel yog dov nyob rau hauv ib qho annular pass uas muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txuas thiab lub taub hau conical. Kev kos duab txias feem ntau ua rau ntawm 0.5 mus rau 100T ib leeg-chain lossis ob-chain txias tshuab kos duab.

1.3. Txoj kev extrusion yog muab lub raj cua sov tso rau hauv lub tog raj kheej kaw, thiab tus pas nrig perforation thiab tus pas nrig extrusion txav ua ke kom cov extrusion feem extruded los ntawm qhov me me tuag qhov. Txoj kev no tuaj yeem tsim cov kav hlau nrog cov kab me me.

2. Siv seamless steel kav

2.1. Seamless kav yog dav siv. General-purpose seamless kav yog dov los ntawm cov pa roj carbon zoo tib yam steel, uas tsis muaj alloy structural steel, los yog alloy structural steel, nrog rau qhov loj tshaj plaws tso zis ntau lawm, thiab tsuas yog siv raws li cov kav dej los yog cov khoom siv rau thauj cov kua.

2.2. Nws tau muab rau hauv peb pawg raws li kev siv sib txawv:

ib. Muab raws li tshuaj muaj pes tsawg leeg thiab txhua yam khoom;

b. Muab khoom raws li cov khoom siv kho tshuab;

c. Muab khoom raws li kev ntsuas hydraulic. Yog tias cov kav dej steel muab raws li pawg a thiab b tau siv los tiv thaiv cov kua siab, lawv yuav tsum tau kuaj xyuas hydrostatic.

2.3. Cov kav dej tshwj xeeb seamless muaj xws li cov kav dej seamless rau boilers, seamless kav rau geology, thiab seamless kav rau roj av.

3. Hom seamless steel kav

3.1. Seamless steel kav yuav muab faib ua cov kav dej kub dov, cov kav dej txias txias, cov kav dej txias, cov kav dej extruded, thiab lwm yam raws li cov txheej txheem ntau lawm.

3.2. Raws li cov duab, muaj cov raj puag ncig thiab cov raj tshwj xeeb-puab. Ntxiv rau cov raj square thiab cov kab plaub hau, cov raj tshwj xeeb zoo li muaj xws li cov raj oval, cov raj semi-circular, daim duab peb sab, raj hexagonal, convex-shaped leeg, plum-puab raj, thiab lwm yam.

3.3. Raws li cov ntaub ntawv sib txawv, lawv tau muab faib ua cov kav dej carbon zoo tib yam, cov kav dej tsis tshua muaj hlau, cov kav dej zoo carbon zoo, cov kav dej hlau alloy, cov kav hlau stainless, thiab lwm yam.

3.4. Raws li lub hom phiaj tshwj xeeb, muaj cov kav dej boiler, geological kav, roj kav, thiab lwm yam.

4. Cov lus qhia tshwj xeeb thiab cov tsos zoo ntawm cov kav dej seamless yog los ntawm GB / T8162-87.

4.1. Specifications: Sab nraud txoj kab uas hla ntawm cov yeeb nkab kub dov yog 32 ~ 630mm. Phab ntsa thickness 2.5 ~ 75mm. Sab nraud txoj kab uas hla ntawm txias dov (txias kos) yeeb nkab yog 5 ~ 200mm. Phab ntsa thickness 2.5 ~ 12mm.

4.2. Cov tsos mob zoo: Sab hauv thiab sab nrauv ntawm cov yeeb nkab steel yuav tsum tsis txhob muaj cov kab nrib pleb, folds, yob folds, sib cais txheej, kab plaub hau, los yog caws pliav tsis xws luag. Cov kev tsis xws luag no yuav tsum tau muab tshem tawm tag nrho, thiab cov phab ntsa tuab thiab sab nraud yuav tsum tsis txhob dhau qhov tsis zoo sib txawv tom qab tshem tawm.

4.3. Ob qhov kawg ntawm cov yeeb nkab steel yuav tsum raug txiav ntawm txoj cai kaum thiab burrs yuav tsum tau muab tshem tawm. Cov kav hlau uas muaj phab ntsa thickness ntau dua 20 hli raug tso cai txiav los ntawm cov roj txiav thiab kub sawing. Nws tseem tuaj yeem tsis txiav lub taub hau tom qab kev pom zoo ntawm cov khoom siv thiab cov neeg xav tau.

4.4. "Nto zoo" ntawm txias-draw los yog txias-dov precision seamless steel kav hais txog GB3639-83.

5. Tshuaj muaj pes tsawg leeg tshuaj xyuas ntawm seamless steel kav

5.1. Cov tshuaj muaj pes tsawg leeg ntawm cov kav dej seamless hauv tsev tau muab los ntawm cov khoom siv tshuaj lom neeg thiab cov khoom siv kho tshuab, xws li No. 88. Imported seamless kav raug tshuaj xyuas raws li cov qauv tsim nyog tau teev tseg hauv daim ntawv cog lus. Cov tshuaj muaj pes tsawg leeg ntawm 09MnV, 16Mn, thiab 15MnV steel yuav tsum ua raws li cov cai ntawm GB1591-79.

5.2. Rau cov txheej txheem kev tshuaj xyuas tshwj xeeb, thov xa mus rau qhov cuam tshuam ntawm GB223-84 "Kev Tshuaj Ntsuam Xyuas Tshuaj rau Hlau thiab Alloys".

5.3. Rau kev tsom xam deviations, xa mus rau GB222-84 "Kev tso cai sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm cov qauv thiab cov khoom tiav rau kev tshuaj ntsuam xyuas ntawm cov hlau".
