Dab tsi yog qhov txawv ntawm 316 seamless yeeb nkab thiab ERW yeeb nkab?

 

AISI 316 stainless hlau seamless yeeb nkabyog lub hollow ntev steel khoom tsim los ntawm austenitic stainless hlau (AISI 316) tsis muaj welded seams thaum lub sij hawm tsim khoom. Nws muaj kev tiv thaiv corrosion zoo heev, siab - kub stability, thiab txhua yam muaj zog, tso cai rau kev pabcuam txuas ntxiv ntawm qhov kub hauv qab 1700℃F (927 degree) thiab kev pabcuam cuam tshuam ntawm qhov kub qis dua 1600℃F (871℃). Nws yog dav siv nyob rau hauv chemical processing, roj av, zaub mov, khoom siv kho mob, marine engineering, tshav kub exchangers, thiab kws industries.

 

Tus nqi ntau yam ntawm AISI 316 stainless hlau seamless kav yog kwv yees li US $ 1,800-4,500 ib tuj, nyob ntawm seb yam xws li specifications, phab ntsa thickness, nto tiav, thiab txiav txim kom muaj nuj nqis. Cov khoom lag luam txheem feem ntau tuaj yeem xa tuaj hauv 7-15 hnub ua haujlwm, thaum cov khoom lag luam customized feem ntau xav tau kwv yees li 15-45 hnub rau kev tsim khoom thiab xa khoom.

 

 

 

AISI 316 Stainless hlau ERW yeeb nkabyog stainless hlau welded yeeb nkab uas tsim los ntawm kev siv hluav taws xob tsis kam vuam (ERW) txheej txheem. Thaum lub sij hawm tsim khoom, stainless hlau sawb yog tsim rau hauv ib puag ncig tubular zoo, thiab siab - zaus hluav taws xob tam sim no ua rau cov hluav taws xob tiv thaiv kom yaj cov yeeb nkab npoo, uas yog tom qab ntawd siab welded ua ke los tsim cov vuam seam. Txoj kev tsim khoom no muaj kev ua tau zoo ntau lawm, tus nqi qis dua, thiab tswj tau qhov vuam zoo, ua rau nws tsim nyog rau loj - nplai ntau lawm. Txawm li cas los xij, thaj chaw weld seam tuaj yeem ua rau muaj kev pheej hmoo me ntsis ntawm kev txhim kho corrosion hauv zos, uas tuaj yeem txo qis los ntawm kev kho cov tshuaj annealing lossis los ntawm kev xaiv cov khoom siv vuam siv los ua kom pom kev zoo corrosion.

 

 

316 seamless yeeb nkab yog tsim los ntawm kev tho ib qho khoom siv, muab kev ua haujlwm siab dua, zoo ib yam, thiab txhim kho corrosion tsis kam nrog tsis muaj seam kab. Hauv qhov sib piv, 316 ERW (Electric Resistance Welded) yeeb nkab yog tsim los ntawm longitudinally vuam steel coils, ua rau nws tus nqi ntau dua - zoo tab sis feem ntau zoo dua rau qis dua - siab, tsawg dua cov ntawv thov.

 

316 Seamless Yeeb Nkab vs. ERW Yeeb Nkab: Qhov Tseem Ceeb Qhov txawv

 

Feature	316 Seamless (SMLS) yeeb nkab	316 ERW (Welded) yeeb nkab
Kev tsim khoom	Ua los ntawm cov khoom siv stainless hlau billet uas yog cua sov thiab tho rau hauv lub raj hollow.	Ua los ntawm lub tiaj tus steel strip / coil uas txias - ua rau hauv lub tog raj kheej thiab welded siv siab - zaus induction.
Weld Seam	Tsis muaj seam. Ua tiav cov qauv txuas ntxiv hla ntawm tus ntoo khaub lig-section.	Longitudinal seam. Ib txoj kab weld khiav tag nrho ntev ntawm cov yeeb nkab.
Siab Muaj Peev Xwm	Siab dua. Tsis muaj cov ntsiab lus tsis muaj zog hauv cov qauv; ua haujlwm siab heev -siab thiab nqus.	qis. Feem ntau ntsuas ntawm 85% -100% ntawm lub zog ntawm seamless vim "Weld Joint Efficiency Factor."
Qhov Loj Muaj	Sab nraud txoj kab uas hla feem ntau 6-830 mm; Phab ntsa Thickness 0.5-60 mm.	Muaj txog li Φ1420 mm (tshwj xeeb tshaj yog ntawm kauv vuam); Txawm li cas los xij, 316 ERW kav feem ntau pom nyob rau hauv me me mus rau nruab nrab diameters.
Ntau lawm ntev	Txwv los ntawm lub tshuab extrusion muaj peev xwm (feem ntau luv dua).	Nws tuaj yeem tsim nyob rau hauv qhov ntev ntev ntev los ntawm coils.
Lead Time & Nqi	Lub sijhawm ua haujlwm ntev dua thiab tus nqi siab dua (kwv yees . 25-40% kim dua).	Lub sij hawm luv luv thiab tus nqi qis dua vim qhov siab - ceev automated ntau lawm.
Cov Standards	ASTM A312, ASTM A213, ASTM A269 thiab ASTM A269.	ASTM A312 (welded), ASTM A249, ASTM A554.

 

SS 316 Seamless (SMLS) yeeb nkab haum rau qhov xav tau ib puag ncig xws li siab - cov kav dej siab hauv kev lag luam petrochemical, boiler raj, hydraulic systems, offshore engineering, thiab cov khoom siv hluav taws xob nuclear.
SS 316 ERW yeeb nkab haum rau tus nqi- siv tau zoo xws li qis- kev thauj cov kua dej (dej, roj), kev tsim qauv, thiab cov kav dej dav dav.

 

 

Tus nqi ntawm 316 seamless yeeb nkab feem ntau yog siab dua li ntawm 316 ERW (Electric Resistance Welded) yeeb nkab; vim muaj ntau txoj kev tsim khoom thiab kev ua haujlwm siab, nws cov nqi feem ntau yog 20% ​​mus rau 30% siab dua. Chav tsev nqi rau seamless yeeb nkab (ASTM A312 TP316) feem ntau yog li ntawm $ 6,595 mus rau $ 8,245 ib tuj, whereas tus nqi tsev rau ERW yeeb nkab thiab lwm yam welded piping khoom poob ntawm $4,200 thiab $7,695 ib tuj.

 

 

 

GNEE muaj ntau yam ntawm 316/316L stainless hlau cov khoom xws li seamless kav, ERW / EFW welded kav, thiab huv si - qib BA raj tag nrho raws li ASTM A312 / A213 / A269 / A358 thiab EN cov qauv. Tsis tas li ntawd, 100% ntawm peb cov khoom tau raug kuaj xyuas hydrostatic thiab eddy tam sim no qhov tsis zoo.
