Nke abụọ, ọdịiche dị n'etiti akụrụngwa
A na-emepụta ọkpọkọ ERW carbon steel nke a na-eji na akụrụngwa sitere na eriri igwe na-ekpo ọkụ mgbe niile, ihe mejupụtara kemịkalụ na akụrụngwa anụ ahụ kwụsiri ike.

Ọtụtụ n'ime ihe ọkụkụ na-ekpo ọkụ na-ekpo ọkụ na-eji obere ihe na-ekpo ọkụ na-ekpo ọkụ, ihe mejupụtara kemịkalụ na akụrụngwa anụ ahụ na enweghị ntụkwasị obi, ntụpọ n'ime na adịghị ọcha ndị ọzọ.Naanị n'ime mmanụ na mmanụ petrochemical n'ime nnukwu ndị na-emepụta ọkpọkọ na-eji ọkụ na-ekpo ọkụ na-ekpo ọkụ mgbe niile na-emepụta ọkpọkọ ígwè iji hụ na ịdị mma na nchekwa.

Nke atọ, ọnụ ahịa ịzụrụ ihe na ihe isi ike ịzụrụ
Mmanụ na petrochemical usoro nke nnukwu ígwè ọkpọkọ mmepụta nke spiral ígwè ọkpọkọ, ya uru na-tumadi lekwasị na nnukwu dayameta ígwè anwụrụ n'ichepụta, n'ichepụta ụgwọ dịtụ ala.Otú ọ dị, n'ihi na obere na ọkara dayameta (Φ114mm ~ Φ355.6mm) nke ígwè ọkpọkọ, n'ichepụta ego dị elu, nkezi dị elu karịa ERW ígwè ọkpọkọ 8% ka 15%.

Nnukwu ụlọ ọrụ ọkpọkọ igwe anaghị emepụta obere dayameta spiral steel pipe, ịzụ ahịa siri ike karị.Obere na ọkara dayameta erw carbon ígwè ọkpọkọ, n'ihi na ọnụ ọgụgụ buru ibu nke emepụta, dị mfe ịzụta.

Nke anọ, ígwè ọkpọkọ geometric size
1, ERW carbon ígwè pipe geometric size nke elu ziri ezi;na spiral welded pipe geometry ziri ezi dị ala, na-ebute n'ebe a na-arụ ọrụ nke weld weld docking ihe isi ike.
2, ERW carbon ígwè anwụrụ weld ọnụọgụ bụ 100%;gburugburu welded ọkpọkọ weld ọnụọgụ nke 130% -200%.Ogologo nke ọkpọkọ spiral dị ogologo karịa nke ọkpọkọ ígwè ERW, ọnụ ọgụgụ ntụpọ ahụ na-abawanyekwa.
3, ERW carbon steel pipe n'ime weld dị nso na efu, anya gba ọtọ adịghị ahụ anya;spiral steel pipe n'ime na n'èzí ga-ahapụrịrị ihe dịka 0.3 mm elu (nke a na-ekpebi site na usoro mmepụta).Weld dị elu nke na enwere ọdịiche dị n'etiti mkpuchi (3PE) na ọkpọkọ, nke na-eme ka nguzogide corrosion nke ọkpọ ígwè na-ebelata nke ukwuu.

4, N'ihi ịdị adị nke spiral steel pipe gap, nnyefe nke ngwa ngwa ngwa ngwa ga-enwe nnukwu ọgba aghara, na-abawanye nguzogide na-asọ asọ, belata ọrụ ụgbọ njem nke pipeline.ERW carbon steel pipe mgbidi dị nro, enweghị nsogbu dị otú ahụ.
