Improving Infrastructure Efficiency with S355 JR Spiral Steel Pipe: A Game Changer for Modern Natural Gas Pipelines Construction
SELELEKELA:
Tlhokahalo e ntseng e eketseha ea matla a sebetsang le e tšepahalang e fetohile kameho ea bohlokoa ka mebuso le liries tse lefatšeng ka bophara. Kaha lipeipi tsa khase ke methapo ea lipalangoang tsa khase, khetho ea lisebelisoa tsa tlhaho e bohlokoa ho netefatsa phepelo ea matla a mangata le e tsitsitseng. Ka blog ena, re hlahloba j355 Jr Spiral Steel Pipe, hape e tsejoang kaPipe ea Glical Seam, e fetola lipeipeli tsa tlhaho tsa khase ea liphallelo, ho ntlafatsa polokeho, ho hloka botsitso le katleho ea lipalangoang.

1. Utloisisa Spira ea Steel Steel Pipe:
S355 Jr Spiral Steel Pipese entsoe ka tšepe e phahameng haholo ea s35 Sebopeho sa sekhele sa spiral se fa lefapha le matlafatsang le ho feto-fetoha le maemo Ho bakoe ha eona ho netefatsa maemo a ka botsitso a kang ho sisinyeha ha lefatše le mobu, ka molumo o tla netefatsa bophelo bo phela o le manyo le 'ona oa pepeng oa tlhaho.
2. Ts'ireletso pele:
Ho tšepahala le polokeho ea likopi tsa khase ea tlhaho ho bohlokoa ho boiketlo ba sechaba le tikoloho. Matla a phahameng le ho tšoarella ha S355 Jr Spiral phala papali ea bohlokoa ho fokotsa kotsi ea ho oela, e hetla le likotsi tse latelang. Ka lebaka la ts'ebetso ea eona ea semmuso ea spiral seam, botšepehi ba pompo bo lula bo le tsitsinyehe esita le tikolohong ea leholimo le feteletseng. Ho kenyelletsa lipeipi tsena ho lipeipi tsa tlholeho ea tlhaho ho fokotsa menyetla ea likotsi tsa tikoloho mme e lumella phallo ea khase ea tlhaho ho felisa basebelisi.

Ho kenyelletsa S355 Jr Spipes ea Steel Spip ka ts'ebetso ea tlhaho ea geroline ea tlholeho e se e netefalitsoe ho ntlafatsa ts'ebetso ea lits'ebeletso tsa lits'ebeletso. Matla a ikhethang a pompoine, likarolo tsa polokeho le tsa polokeho li tsamaisa phallo ea tlhaho ea khase ea tlhaho, e fokotsang menyetla ea likotsi, likotsi tsa tikoloho le litšenyehelo tsa tikoloho le litšenyehelo tsa tikoloho. Ka ho fetola katleho ea lipalangoang le ho fokotsa mekhoa ea matla, pompo ea kelello e bapala ka tlhokahalo ea ho hola ha u ntse u batla litloaelo tse tsitsitseng. Ho tsetela ka tharollo ea S355 Jr Spiral Phala e bohlokoa bakeng sa mebuso, indasteri ho netefatsa monyetla oa bokamoso bo hloekileng.
