SAE 1020 Precision Seamless Steel Pipe

Kufotokozera Kwachidule:

SAE 1020 Precision Seamless Steel Pipe amapangidwa kudzera mu annealing owala kapena kugudubuzika kwapadera kozizira.

So SAE 1020 Precision Seamless Steel Pipe ndi mtundu wa chitoliro chopanda chitsulo chomwe chimapangidwa ndi zabwino zingapo:

1.Mkati ndi kunja pamwamba palibe zokutira okusayidi;

2. Kunyamula kuthamanga kwambiri, popanda kutayikira;

3.Pamwamba posalala;

4.Palibe kukonzanso mu kupindana kozizira, palibe ming'alu panthawi ya kuyesa kwamoto, ndi kuyesa kwa flattening.

5.Kulolera pang'ono, mkati mwa+/-0.05mm

Ndi zabwino izi chimagwiritsidwa ntchito magalimoto, njinga zamoto, mphamvu yamagetsi, makina, Chalk hayidiroliki, mayendedwe, zigawo pneumatic, masilindala mafuta, migodi malasha, mayendedwe, zida boiler, mapaipi, engineering etc.

Makulidwe a Chitoliro

Kukula kwa chitoliro kumatchulidwa ndi manambala awiri osayang'ana mbali:

Kukula Kwapaipi Kwadzina (NPS) kwa mainchesi kutengera mainchesi.

Nambala ya Ndondomeko (SCH kuti mufotokoze makulidwe a khoma la Pipe.

Zonse kukula ndi ndondomeko zimafunika kuti zifotokoze molondola chidutswa china cha chitoliro.

Nominal Pipe Size (NPS) ndiye North America Seti yamakono yamapaipi omwe amagwiritsidwa ntchito pazovuta zazikulu komanso zotsika komanso kutentha.Kukambitsirana kwina kwa izi kuli pano.

Kukula kwa Iron Pipe (IPS) inali muyeso wakale kuposa NPS kufotokoza kukula kwake.Kukula kwake kunali pafupifupi m'mimba mwake mwa chitolirocho inchi.Chitoliro chilichonse chinali ndi makulidwe amodzi, otchedwa (STD) Standard kapena (STD.WT.) Standard Weight.Pa nthawiyo panali makulidwe a makoma atatu okha.Mu Marichi 1927, bungwe la American Standards Association linapanga dongosolo lomwe lidasankha makulidwe a khoma kutengera masitepe ang'onoang'ono pakati pa kukula kwake ndikuyambitsa Nominal Pipe Size yomwe idalowa m'malo mwa Iron Pipe Size.

Nambala yandalama ya makulidwe a khoma kuyambira SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS (Yowonjezera Yamphamvu) NDI XXS (Double) Wamphamvu).

Mgwirizano Wachidwi wa Pipe ndi Tubing

BPE - Black Plain End Pipe

BTC - Black Threaded & Coupled

GPE - Galvanized Plain End

GTC - Yopangidwa ndi Galvanized & Coupled

TOE - Yopangidwa Ndi Mapeto Amodzi

Zopaka mapaipi & Zomaliza:

Galvanized - Kukutidwa ndi zokutira zinki zoteteza pazitsulo kuti zinthu zisachite dzimbiri.Njirayi imatha kukhala yotentha-kuviika-galvanizing pomwe zinthuzo zimamizidwa mu zinki wosungunuka kapena Electro-Galvanized pomwe pepala lachitsulo lomwe chitolirocho limapangidwira lidapangitsidwa ndi mphamvu panthawi yopanga ndi electro-chemical reaction.

Osakutidwa - Chitoliro chosatsekedwa

Black Coated - Wokutidwa ndi chitsulo chakuda chakuda

Red Primed -Red Oxide Primed yomwe imagwiritsidwa ntchito ngati chovala choyambira zitsulo zachitsulo, imapatsa chitsulo ndi chitsulo pamwamba pachitetezo.
