Tsananguro pfupi:

Womic Steel inopa pombi dzesimbi dzemhando yepamusoro dzeASTM A53 Giredhi B LSAW dzemafuta, gasi, mvura, uye steam transmission dzine simba rakaderera kusvika pakati nepakati, pamwe nekushandiswa kwechimiro nekwemakanika. Giredhi B rinopa simba rekugadzira 240 MPa (35,000 psi) uye simba rekubata 415 MPa (60,200 psi), zvichiita kuti ive giredhi repombi rakanyanya kutaurwa kune masisitimu emapaipi emaindasitiri neemabhizinesi. Maitiro eLSAW anosanganisira nzira dzeJCOE, UOE, uye rolled plate welding, zvichipa musono wakatwasuka we longitudinal une mhando yakagadzikana uye divi rakagadzikana. Kune dhayamita hombe kana madziro anorema (kusvika pakukora kwemadziro kwe60mm), Womic inoshandisa plate rolling uye multi-pass submerged arc welding. Dhayamita yekunze kubva pa219mm kusvika 1,422mm (8″ – 56″), ukobvu hwemadziro kubva pa5.0mm kusvika 60mm, kureba kusvika pa24m. Chitupa chemugayo, bvunzo yemvura (inosarudzwa kushandiswa muchimiro), bvunzo ye ultrasonic 100%, magumo akachekwa kana asina kujeka, uye coating inodzivirira ngura (FBE, 3LPE, epoxy) zviripo. Zvakakodzera migero yemvura, masisitimu emhepo yakamanikidzwa, kugoverwa kwegasi rechisikigo rine simba shoma, mapaipi ekudzivirira moto, rutsigiro rwechimiro, kurongedza, uye mapaipi ekushanda mumaindasitiri.

Saizi yepombi yesimbi yeLSAW:Dhayamita yekunze: 219mm – 1,422mm (8″ – 56″), Ukobvu hwemadziro: 5.0mm – 60mm (JCOE/UOE yakanyanya 50.8mm, plate yakakungurutswa yakanyanya 60mm), Kureba: 6m – 18m yakajairwa, urefu hwakatarwa hunosvika 24m

●Kuongororwa kwebato rechitatu kuripo

Mibvunzo Inowanzo bvunzwa:

Mubvunzo: Ko ASTM A53 Giredhi B yakakodzera here pamigero yemvura?
A: Ehe, ndiyo nzira inonyanya kushandiswa pakutumira nekugovera mvura yemumaguta. Pamvura inonwiwa, iva nechokwadi chekuti kufukidza kana kufukidza kwakakodzera (epoxy lining inokurudzirwa). Pamvura isina kubikwa kana kudiridza, pombi isina chinhu inogamuchirwa.

Mubvunzo: Pombi yeA53 Grade B LSAW inogona kushandiswa here kugadzira gasi rechisikigo?
A: Ehe, pakuparadzirwa kwesimba rakaderera (kazhinji pasi pe2 MPa). Kana simba rakawanda richikwira, API 5L GR.B kana X42 inokurudzirwa. Nguva dzose tarisa makodhi emunharaunda.

Mubvunzo: Ndeupi musiyano uripo pakati peASTM A53 Grade B neAPI 5L GR.B?
A: Ane hunhu hwakafanana hwemakanika (240 MPa vs 245 MPa goho). API 5L ine miganhu yemakemikari yakamanikana (P yakaderera, S) uye kuyedzwa kwakasimba kwekushandiswa kwepombi dzetambo. Pakushandiswa kwemvura nechimiro, A53 yakakwana. Pamapaipi emafuta negasi, API 5L ndiyo inosarudzwa.

Mubvunzo: Ko A53 inoda kuongororwa kwe hydrostatic here?
A: ASTM A53 inoda kuyedzwa kwemvura isina musono (Type S) uye kwepombi yeERW (Type E) kana zvataurwa. Kune mapaipi eLSAW akagadzirwa kuA53, kuyedzwa kwemvura kunowanzoitwa chete kana odha yacho yataura. Mashandisirwo mazhinji emvura ane chivakwa uye ane simba shoma haabvumi kuyedzwa kwemvura.

Mubvunzo: Munogona here kupa A53 Grade B galvanizing inodziya?
A: Ehe. Tinopa galvanizing inopisa paASTM A123. Hurefu hwepamusoro hwe12.5m. Kune mapaipi akareba, tinokurudzira galvanizing yechikamu kana primer coating.

Q: Ndeipi nguva yakajairika yekuisa pombi yeA53 Grade B LSAW?
A: Mazuva makumi maviri kusvika makumi matatu ehukuru hwakajairika. Kune dhayamita hombe kana madziro anorema, mazuva makumi matatu nemashanu kusvika makumi mana nemashanu.
