mipiringidzo yachitsulo yogulitsa A350 LF2 Steeel bar
Pofuna kufafanizira mapaipi, ndikofunikira kuchotsa payipi yolunjika pa mapaipi. Mukamagwiritsa ntchito ma piipelines osiyanasiyana, mapaipi osiyanasiyana ayenera kugwiritsidwa ntchito. Pamene mapaipiwo amagwiritsidwa ntchito, chikopa chiyenera kugwiritsidwa ntchito kusintha kukula kwa mapaipi. Mukamacheza, chipika chanjira zitatu chowonekacho chimagwiritsidwa ntchito ngati cholumikizira cholumikizira, kuti chikhazikitse chipani cholumikizirana kapena kukula kwa nthawi yayitali komanso cholumikizira cholumikizira cha mapaipi. , Pakulumikizana ndi zida zosiyanasiyana, palinso zolumikizira ndi mapulagini a gawo la chida.
ASME A234 ndi lingaliro lokhazikika la zoumba za chitoliro cha zitsulo za mkaka wa zitsulo ndi alloy. Mitundu yachitsulo ya cape yopangidwa kuti ikhale a234 nthawi zambiri imakhala yotentha mogwirizana ndi asme B16.9 kapena asme B16.49. Pali zitsulo ziwiri zachitsulo: wpb ndi wpc, zomwe Astm A234 WPB imagwiritsidwa ntchito nthawi zambiri m'makampani opanga mapaipi. The A234 WPB Butting-World Puttings ikuphatikiza zingwe, zobwera, zimabwezedwa, ma tees, ma cups, mitanda, ma stants and cunts.
Ma boti a carbon matonge okhala ndi mikaka pakati pa 0,60 - 1.25%. Mitundu yapamwamba ya carbon imalola ili ndi Manganese omwe ali ndi 0,30 - 0.90%. Mwa magiredi onse atatu, ma carbon steel ndodo yolumikizidwa imakhala ndi kuuma kwambiri komanso kulimba kwambiri ndikuwonetsa otsika kwambiri. Kuchepetsa kwambiri kukana kumabwera chifukwa chakuti zomata izi zimawumitsidwa nthawi zonse komanso zimakwiya.
A234 wpb steel chitoliro chimatanthawuza chitoliro choyenera cha Astm A234 wplestems amitundu yosiyanasiyana. ndi grade b, onani mphamvu zochepa, monga anyezi A106 A53, GR.B 5l GR.B.B.
