Hlau hluabraiding ntev yuav tsum tau raws li nram no.

1. Lub tes tsho ntev yog 15-20 npaug ntawm cov hlua hlau txoj kab uas hla, lub tes tsho me me feem ntau yog 40 ~ 50 npaug ntawm txoj kab uas hla.

2. Rau qhov tseem ceeb ntawm txoj hlua, qhov sib koom ua ke ntev tuaj yeem nce mus rau 80 ~ 100 zaug, yog li txoj hlua khawm pob tw tseem hu ua luv ntxig.

3. Feem ntau ib leeg-stranded sib koom ua ke ntawm lub pob tw loj (txoj kev sib txuas loj) ntev yog 180 npaug ntawm txoj kab uas hla ntawm txoj hlua hlau, uas yog, ib lub taub hau hlau hlua, raws li peb strands suav, qhov ntev ntawm kev txiav yuav tsum tau lav ntau dua 3X180d. ob kawg ntev ntawm 2X3X180d.Piv txwv li, φ24.5 hlau hlua, tom qab ib tug loj rub, yuav tsum tau muab tso rau 2X3X180 X24.5 = 26460 mm.

4. Coated phosphatesteel hlau hlua, steel hlau los ntawm manganese los yog zinc-manganese phosphate kev kho mob, phosphate zaj duab xis thiab roj compound nyhuv, steel hlau hnav tsis kam, corrosion kuj, xeb kuj dhia nce siab, qaug zog lub neej rau tib lub qauv glossy steel hlau hlua 3 zaug, tuaj yeem txheeb xyuas los ntawm qaug zog kuaj lub neej qaug zog, yog qhov kev txhim kho ntawm glossy steel hlau hlua, tuaj yeem hloov thawj plating tom qab rub nyias txheej ntawm galvanized steel hlau hlua.

A, kev siv cov hlua hlau yooj yim yuav tsum tau ua.
Ua ntej siv yuav tsum xyuas cov hlua tsis muaj kev puas tsuaj;Hlau hluatsis tuaj yeem muaj kev nruj nruj, lub nplhaib, dhia kab, flattening thiab lwm yam tsis xws luag;Hlau hlau hlua knotted rau hauv ib txoj hlua teeb, tsawg kawg yog siv peb daim npav, xws li kev siv txoj hlua khi hlua khi, qhov ntev ntawm nws txoj hlua khi tsis pub tsawg dua 15 npaug ntawm txoj kab uas hla ntawm cov hlua hlau, qhov luv tshaj yuav tsum tsis txhob tsawg dua. ntau tshaj 30 cm;Txwv tsis pub siv txoj kev knotting los txuas cov hlau hlua hlua, winch nrog steel hlau hlua yuav tsum tsis txhob nrog cov pob qij txha;Siv xws li cov roj to phenomenon (tshwj tsis yog rau txoj hlua tshiab), uas qhia tau hais tias txoj hlua hlau deformation yog loj heev, yuav tsum tam sim ntawd nres ua hauj lwm, xyuas cov txheej txheem;Cov hlua hlau yuav tsum tau ua kom huv si, feem ntau ib xyoos ib zaug poob roj, nrog cov hlua hlua roj los yog lub tog raj kheej roj, thiab lwm yam. (roj kub yuav tsum tsis pub tshaj 80 ℃);Nqa molten hlau (steel, hlau dej pob) xaim hlua, hlua core yuav tsum yog cov khoom siv ntuj tsim (asbestos lossis mos hlau ua) steel, pob dej hlau yuav tsum muab tso rau ntawm lub rwb thaiv tsev baffle, thiaj li tsis txhob xaim hlua Rhaub;bundles nrog steel hlau hlua, thaum muaj cov khoom ntse-edged yuav tsum tau padded, khaws qhov sib npaug ntawm cov khoom dai, hlawv hlau yuav tsum tsis txhob bundled.

Galvanized steel hlau hlua, kub-dip galvanized thiab electro-galvanized,stainless hlau hlau hlua, 304 los yog 316 stainless hlau, los tiv thaiv corrosion tab sis kim sab nraum polyethylene los yog polypropylene coated steel hlau hlua, raws li steel hlau hlua yuav tag nrog phosphate coated steel hlau hlua es tsis txhob glossy steel hlau hlua.
