X60 Line Pipe, E kewara ọgwụgwọ ikpo ọkụ n'elu ụzọ abụọ, otu bụ ọgwụgwọ kemịkalụ kemịkalụ, otu bụ ikpochapụ elu na ọgwụgwọ okpomọkụ, usoro ule siri ike bụ nke a:

[1] Ọgwụ ọkụ kemịkalụ nke pipeline X60
-- Ọgwụgwọ okpomọkụ nke kemịkalụ bụ ime ka elu X60 pipeline tube banye n'otu ma ọ bụ ọtụtụ atom mmewere kemịkalụ, ka ọ gbanwee ihe mejupụtara kemịkalụ, usoro na akụrụngwa nke elu tube pipeline X60.Mgbe emenyụchara na okpomọkụ dị ala, elu nke ọkpọkọ pipeline X60 nwere ike siri ike, na-eyi nguzogide na ike ike ọgwụgwụ, na isi nke ọkpọkọ pipeline X60 nwere nnukwu ike na ike.

-- The isi teknuzu paramita nke chemical okpomọkụ ọgwụgwọ X60 pipeline bụ omimi nke obi tara mmiri oyi akwa na elu hardness.A ga-anwale omimi nke oyi akwa siri ike site na vicker hardness tester.Tulee anya site na elu ọkpọkọ X60 ruo n'ókè ebe ike na-adaba na 50HRC.Nke a bụ omimi dị irè nke ọgwụgwọ kemịkalụ siri ike nke X60 pipeline tube n'elu ule siri ike na ọgwụgwọ okpomọkụ siri ike nke nchọpụta pipeline X60, nwere ike iji vicker hardness tester, elu rockwell hardness tester ma ọ bụ rockwell hardness tester iji nwalee, naanị ọkpụrụkpụ nke nitriding siri ike, n'ozuzu ọ bụghị ihe karịrị 0.7 mm, mgbe ahụ enweghị ike iji rockwell hardness tester, Microhardness tester nwere ike iji.

[2] X60 pipeline elu quenching na tempering okpomọkụ ọgwụgwọ
-- Ngwunye elu na ọgwụgwọ okpomọkụ na-emekarị site na ikpo ọkụ induction ma ọ bụ ikpo ọkụ ọkụ.The isi teknuzu paramita bụ elu ekweghị ekwe, obodo ike ike na irè hardening oyi akwa omimi.Enwere ike iji ihe nnwale ike ike Vickers mee nnwale ike, rockwell ma ọ bụ n'elu Rockwell hardness tester.Nhọrọ nke ike nnwale (ọnụọgụ) metụtara omimi nke oyi akwa siri ike dị irè na ike elu nke pipeline X60.Enwere ụdị mita ike ike atọ metụtara.

Vickers hardness tester bụ ụzọ dị mkpa iji nwalee ike nke okpomọkụ a na-emeso ọkpọkọ pipeline X60.Ọ nwere ike iji 0.5 ~ 100kg ule ike nwalee elu hardening oyi akwa ka mkpa dị ka 0.05mm.Izi ezi ya bụ nke kachasị elu, ọ nwekwara ike ịmata ọdịiche dị nta nke ịdị ike elu nke okpomọkụ na-emeso ọkpọkọ pipeline X60.Ke adianade do, omimi nke irè hardening oyi akwa na-atụ site vickers hardness tester, n'ihi ya, ọ dị mkpa iji kwadebe a Vickers hardness tester maka nkeji na-ebu elu okpomọkụ ọgwụgwọ ma ọ bụ na-eji a ọnụ ọgụgụ buru ibu nke elu okpomọkụ ọgwụgwọ workpiece.

-- Ihe nleba anya Rockwell hardness tester dịkwa mma maka ịnwale ike nke ọkpọkọ pipeline X60 siri ike.Enwere akpịrịkpa atọ maka nleba anya Rockwell hardness tester ịhọrọ site na ya.Nwere ike ịnwale ahịrị X60 dị elu dị iche iche nwere omimi siri ike dị irè karịa 0.1mm.Ọ bụ ezie na nkenke nke elu Rockwell hardness tester adịghị elu dị ka vicker hardness tester, ọ nwere ike imezu ihe ndị a chọrọ dị ka usoro nnwale maka njikwa mma na nleba anya n'ime ụlọ ọrụ ọgwụgwọ okpomọkụ.Ọzọkwa, ọ na-nwere àgwà nke mfe ọrụ, adaba ojiji, ala price, ngwa ngwa nha, na ike ozugbo na-agụ ekweghị ekwe uru, wdg Elu Rockwell hardness tester nwere ike ji mee ihe maka ogbe nke elu okpomọkụ ọgwụgwọ X60 pipeline ọkpọkọ ngwa ngwa na-abụghị. ule na-emebi emebi.Nke a dị oke mkpa maka nhazi pipeline X60 na ụlọ nrụpụta igwe.

-- A pụkwara iji ihe nnwapụta Rockwell hardness tester mgbe oyi akwa siri ike dị elu.Mgbe ọkpụrụkpụ nke oyi akwa oyi akwa nke ọgwụgwọ okpomọkụ bụ 0.4 ~ 0.8mm, HRA ọnụ ọgụgụ nwere ike ji mee ihe, mgbe ọkpụrụkpụ nke ike oyi akwa bụ ihe karịrị 0.8mm, HRC ọnụ ọgụgụ nwere ike iji.

-- Vickers, Rockwell na Surface Rockwell ụkpụrụ siri ike nwere ike gbanwee ngwa ngwa ka ọ bụrụ ọkọlọtọ, eserese ma ọ bụ ụkpụrụ siri ike nke onye ọrụ chọrọ.Enyere tebụl ngbanwe kwekọrọ na ọkọlọtọ mba ụwa ISO, ọkọlọtọ American ASTM na ọkọlọtọ China GB/T.

[3] Ọgwụgwọ okpomọkụ nke mpaghara
-- Ọ bụrụ na esiri ike mpaghara nke akụkụ dị elu, enwere ike ịme ọgwụgwọ okpomọkụ nke mpaghara site na ikpo ọkụ induction na ụzọ ndị ọzọ.Ọkpụkpọ pipeline X60 dị otú ahụ na-achọkarị akara ebe ebe ọgwụgwọ okpomọkụ na-ekpochapụ mpaghara na uru isi ike mpaghara dị na eserese ahụ.A ga-eme nnwale siri ike nke ọkpọkọ X60 na mpaghara a họpụtara.Ngwa ule ike siri ike nwere ike iji ihe nleba anya Rockwell, nwalee uru ike ike HRC, dị ka oyi akwa na-ekpo ọkụ na-ekpo ọkụ na-emighị emi, nwere ike iji elu Rockwell hardness tester, nwalee uru HRN siri ike.
