Cov yam ntxwv ntawm Cov Qauv Hlau rau Nkoj

Shipbuilding steel feem ntau yog hais txog steel rau cov qauv hull, uas yog hais txog cov hlau siv los tsim cov qauv hull uas ua raws li qhov yuav tsum tau ua ntawm kev faib tawm hauv zej zog kev tsim kho tshwj xeeb. Nws feem ntau xaj, teem sijhawm thiab muag raws li cov hlau tshwj xeeb. Ib lub nkoj suav nrog cov nkoj nkoj, cov hlau zoo li tus, thiab lwm yam.

Tam sim no, ntau lub tuam txhab hlau loj hauv kuv lub teb chaws muaj ntau lawm, thiab tuaj yeem tsim cov khoom siv marine steel raws li cov neeg siv khoom xav tau hauv ntau lub teb chaws, xws li Tebchaws Meskas, Norway, Nyiv, Lub Tebchaws Yelemees, Fabkis, thiab lwm yam. Cov lus qhia tshwj xeeb yog raws li hauv qab no:

(1) Ntau yam specifications

Cov qauv hlau rau cov hulls tau muab faib ua qib zog raws li lawv qhov tsawg kawg nkaus qhov taw qhia: lub zog dav dav hlau thiab lub zog loj cov qauv hlau.

Lub zog ntawm cov qauv hlau tau teev tseg los ntawm Tuam Tshoj Classification Society tau muab faib ua plaub theem zoo: A, B, D, thiab E; lub siab-zog steel qauv teev los ntawm Tuam Tshoj Classification Society muab faib ua peb theem zog thiab plaub theem zoo:

A32 A36 A40
D32 D36 D40
E32 E36 E40
F32 F36 F40

(3) Kev ceev faj rau kev xa khoom thiab kev lees txais cov khoom lag luam marine steel:

1. Kev tshuaj xyuas ntawm daim ntawv pov thawj zoo:

Lub Hoobkas steel yuav tsum xa cov khoom raws li tus neeg siv khoom xav tau thiab cov lus qhia tshwj xeeb tau pom zoo hauv daim ntawv cog lus thiab muab daim ntawv pov thawj zoo. Daim ntawv pov thawj yuav tsum muaj cov ntsiab lus hauv qab no:

(1) Cov kev xav tau tshwj xeeb;

(2) Cov ntaub ntawv pov thawj zoo thiab tus lej pov thawj;

(3) Rauv batch naj npawb, technical level;

(4) Tshuaj muaj pes tsawg leeg thiab txhua yam khoom;

(5) Daim ntawv pov thawj pom zoo los ntawm pawg neeg sib faib thiab kos npe ntawm tus neeg soj ntsuam.

2. Kev tshuaj xyuas lub cev:

Rau kev xa khoom ntawm marine steel, cov khoom siv lub cev yuav tsum muaj cov chaw tsim khoom lub logo, thiab lwm yam tshwj xeeb:

(1) Kev pom zoo ntawm pawg neeg pom zoo;

(2) Siv cov xim pleev xim rau thav duab lossis muab tshuaj txhuam cov cim, suav nrog cov khoom siv xws li: lub tshuab hluav taws xob batch naj npawb, cov qauv kev qhia tshwj xeeb, qhov ntev thiab dav qhov ntev, thiab lwm yam.;

(3) Cov tsos yog du thiab du, tsis muaj qhov tsis xws luag.
