Q: Kedu mkpuchi a na-atụ aro maka ikpo mmiri?
A: Maka gburugburu mmiri mmiri, a na-ejikarị kol tar epoxy (ọkpụrụkpụ nke 600-800 microns) ma ọ bụ iko flake epoxy eme ihe. Maka mpaghara ebe a na-agba mmiri, anyị na-akwado FBE ma ọ bụ 3LPE nwere ike iguzogide abrasion ọzọ. Maka mmiri ma ọ bụ ala dị ọcha, paịpụ ojii nkịtị ma ọ bụ elu mmanụ na-ezurukarị.

Q: Kedu ka ị si eme ka ndị na-agba ígwè dị ndụ site na hama?
A: Anyị na-eme 100% UT nke njikọta weld yana MPI (nyocha ihe ndọta magnetik) nke mkpịsị ụkwụ weld iji chọpụta mgbawa elu ọ bụla. Anyị na-emekwa nnwale mgbagọ eduzi na ihe nlele weld iji chọpụta ike ductility. Maka ikpo ọkụ dị mkpa, anyị nwekwara ike inye nnwale mmetụta Charpy na 0°C ma ọ bụ ala.

Q: Kedu oge ndu nkịtị maka ọkpọkọ ọkpọkọ ọkwa nke atọ?
A: Oge ndu ọkọlọtọ: ụbọchị 30-45 maka dayameta ≤ 1,422mm. Maka nnukwu paịpụ efere a kpụrụ akpụ (> 1,422mm): ụbọchị 45-60. Maka ikpo osisi ndị dị ogologo a kpụrụ akpụ (ruo mita 60): tinye izu 2-3 maka ịgbado ọkụ na inyocha gburugburu.
