Piling ọkpọkọ
Okwu mmalite
Ụkpụrụ ihe:
A na-ekewakarị ọkpọkọ piling dabere na ihe eji eme ha, nke nwere ike ịgụnye carbon steel, alloy steel, ma ọ bụ ihe ndị ọzọ. Ụkpụrụ ihe a kapịrị ọnụ ga-adabere na ngwa a chọrọ na gburugburu ebe a ga-eji piling pipe.
Ụkpụrụ nrụpụta:
Usoro nrụpụta nke piling pipe nwere ike ịchọ nnabata na ụkpụrụ akọwapụtara iji hụ na ịdị mma, ntụkwasị obi na arụmọrụ nke ọkpọkọ. Enwere ike ịmepụta ụkpụrụ ndị a site na otu dị ka American Society for Testing and Materials (ASTM), American Petroleum Institute (API), ma ọ bụ òtù mba ma ọ bụ mba ndị ọzọ dị mkpa.
Ụkpụrụ imewe:
Enwere ike ịchọrọ ọkpọkọ piling iji zute ụfọdụ ụkpụrụ imewe iji hụ na nguzobe n'usoro ha na ikike ibu ibu. Enwere ike ịmepụta ụkpụrụ ndị a site n'aka ndị injinia na ụlọ ọrụ ihe owuwu ma ọ bụ ụlọ ọrụ na-achịkwa gọọmentị.
Ụkpụrụ nrụpụta:
Usoro nrụpụta nke Submerged-Arc Welded Steel Pipes nwere ike ịgbaso ụkpụrụ akọwapụtara nke otu dị ka American Petroleum Institute (API), American Society for Testing and Materials (ASTM), ma ọ bụ ụlọ ọrụ ụkpụrụ mba ma ọ bụ mba ndị ọzọ dị ka ndị a: API. 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711, EN10217, EN10219
Usoro ngwa:
Enwere ike ịkewa ọkpọkọ piling dị ka ebumnuche ha si dị, dị ka ikpokọta mmiri, ikpo ntọala, ma ọ bụ ụdị ala ma ọ bụ ọnọdụ ala. Ọ dị mkpa ịgakwuru ụkpụrụ kpọmkwem na nhazi ọkwa jikọtara ya na ụdị piling pipe chọrọ maka otu ọrụ. Ọ bụrụ na ị nwere njirisi akọwapụtara ma ọ bụ nhazi ọkwa, biko nweere onwe gị ịnye nkọwa ndị ọzọ ka m nwee ike ịnye ozi ezubere iche.
