ASTM A252 Vasega 3 Va'aiga lautele

ASTM A252paipa uʻamea o se mea masani faapalaga paipa cylindrical ufiufi uma uelo ma seamless ituaiga mo uʻamea faupuʻe paipa o loʻo faʻaaogaina se uʻamea uʻamea e avea o se sui tauave-ave tumau po o se atigi e fausia ai se faaputuga sima lafo-i-nofoaga.

Vasega 3o le togi aupito maualuga lea o togi e tolu o le A252, ma le la'ititimalosi e maua ai le 310MPa [45,000 psi]ma le itiiti ifomalosi fa'amalosi o le 455MPa [66,000 psi].Pe a faʻatusatusa i isi togi, Vasega 3 e sili atu ona talafeagai mo fausaga e faʻatatau i avega mamafa poʻo i totonu o siʻosiʻomaga e sili atu ona faigata, ma e masani ona faʻaaogaina i le fausiaina o faavae mo alalaupapa tetele, fale maualuluga, poʻo luga ole matafaga.

ASTM A252 Vasega Fa'avasegaga

A252 ua vaevaeina i ni togi se tolu e feagai ai ma siosiomaga faʻaoga eseese.

Vasega 1,Vasega 2, maVasega 3.

Fa'ateleina fa'ainisinia.

Vasega 1e masani ona fa'aaogaina i talosaga e lelei le lelei o le palapala ma e le maualuga tele le mana'omia o le amoina.O faʻataʻitaʻiga e aofia ai faavae faʻavae mama mo fale nofoia poʻo fale faʻapisinisi, poʻo ni alalaupapa laiti e le manaʻomia ni uta tetele.

Vasega 2e fetaui lelei mo faʻaoga ma tulaga eleelea leaga poʻo manaʻoga maualuga o le amoina.Mo se faʻataʻitaʻiga, alalaupapa feololo le utaina, fale faʻapisinisi tetele, poʻo atinaʻe o fale faitele.E mafai foi ona faʻaaogaina i nofoaga e maualuga ai le vai, e pei o vaitafe ma vaituloto, lea e manaʻomia ai le malosi o le faʻaleagaina.

Vasega 3e faʻaaogaina mo manaʻoga mamafa i tulaga ogaoga, e pei o alalaupapa tetele, faʻavae meafaigaluega mamafa, poʻo galuega faʻavae loloto mo fale maualuluga.E le gata i lea, mo tulaga faʻapitoa faʻafanua, e pei o eleele vaivai tele pe le mautu, Vasega 3 e ofoina atu le maualuga maualuga o le amoina ma le mautu.

Matou te ofoina atu foi le tele o mea faʻapipiʻi ma flanges e faʻafetaui ai manaʻoga o galuega faʻapipiʻi eseese.

A e filifilia Botop Steel, e te filifilia le lelei ma le faʻamaoni.

Gaosiga Fa'agasologa

ASTM A252 Pipe Pile Pipes e mafai ona fa'avasegaina i ni fa'agasologa autu o gaosiga e lua:fa'alelei ma uelo.

I le faiga uelo, e mafai ona toe vaevaeina iERW, EFW, maSA.

SAW e mafai ona fa'avasegaina iLSAW(SAWL) maSSAW(HSAW) faʻalagolago i le itu o le uelo.

Talu ai o le SAW e masani ona faʻapipiʻiina i le faʻaogaina o le faʻaogaina o le faʻaogaina o le faʻaogaina o le arc, e masani ona taʻuaDSAW.

O nei auala gaosiga eseese e mafai ai e le ASTM A252 tubular pile paipa ona faʻafetaui le tele o manaʻoga inisinia.

O lo'o taua i lalo le fa'asologa o le gaosiga o le paipa u'amea (SSAW):

SSAW Gaosiga Fa'agasologa

SSAW paipa uameae fetaui lelei mo le gaosiga o paipa u'amea lapoa ma e mafai ona gaosia i le lautele e oo atu i le 3,500mm.E le gata e mafai ona gaosia i ni uumi uumi, lelei mo fausaga tetele, ae sili atu le taugofie o paipa uʻamea SSAW pe a faʻatusatusa i paipa uʻamea LSAW ma SMLS.

Fuafuaga Tele

O le Botop Steel e mafai ona ofoina atu le tele o laina faʻapipiʻi o faʻamau:

Vaega Kemisi o le ASTM A252 Vasega 3

Ole mea ole phosphorus e le sili atu ile 0.050%.

Ole mea e mana'omia ile vaila'au mo le ASTM A252 e faigofie pe a fa'atusatusa i isi tulaga paipa mo isi fa'aoga aua pe a fa'aogaina le paipa e fai ma fa'aputuga paipa, e matua fa'avae i le natura.Ua lava le mafai e le paipa uʻamea ona tatalia avega manaʻomia ma tulaga tau le siosiomaga.O lenei kemisi fa'afaigofie e fesoasoani i le fa'asilisiliina o le tau ma le gaosiga a'o fa'amalieina mana'oga autu o le saogalemu ma le tumau.

Galuega Fa'ainisinia o le ASTM A252 Vasega 3

Galuega Fa'ainisinia o le ASTM A252 Vasega 3

ASiata 2 o lo'o tu'uina mai ai tau fa'atatau aupito maualalo:

ASTM A252 Laulau 2

Afai o le mafiafia o le puipui fa'amauina e vaeluagale i mea o lo'o fa'aalia i luga, o le tau fa'aumiumi aupito maualalo e tatau ona fuafuaina e fa'apea:

Vasega 3: E = 32t + 10.00 [E = 1.25t + 10.00]

E: elongation i le 2 inisi [50.8 mm], %;

t: fa'amauina le mafiafia o puipui, i. [mm].

Siata o le mamafa o paipa

Mo le tele o faaputuga paipa e le o lisiina i le siata o le mamafa o paipa, o le mamafa i le umi o le paipa e tatau ona fuafuaina e pei ona taua i lalo:

W = 10.69(D - t)t [ W = 0.0246615(D - t)t ]

W = mamafa ile iunite umi, lb/ft [kg/m].

D = fa'amaoti le lautele i fafo, i. [mm],

t = mafiafia fa'amauina o puipui, i. [mm].

Fa'apipi'i i luga o paipa uamea

 

O la matou kamupani e ofoina atu le tele o ituaiga faʻapipiʻi e aofia ai le vali, varnish, galvanized, zinc-rich epoxy, 3LPE, coal tar epoxy, ma isi mea e faʻafetaui ai manaʻoga o galuega eseese ma faʻamautinoa le tumau umi.
