Collars drile
Tha collar drile mar aon phàirt de shreang drile na thubularan air leth tionnsgalach a thathas a’ cleachdadh airson drileadh a-steach don talamh gus cuideam a chuir air pìos airson drileadh.Tha e air a chleachdadh airson co-cheangal ri pìob drile.Tha seòrsaichean slick agus snìomhanach ann gu ìre mhòr.Tha ar pròiseas saothrachaidh air a dhearbhadh gu API spec 7-1.Tha an collar drile air a dhèanamh de stàilinn alloy atharraichte AISI 4145 H no 4145 H.Bithear a’ trepanadh tuill bho aon taobh gun choimeas.Tha na coilearan drile uile air an làimhseachadh le teas le cruas taobh a-staigh 285 gu 341 BHN, a tha cinnteach aon òirleach fo uachdar na pìoba.
Bidh coilearan drile neo-magnetach a’ tabhann neart agus cruas fhad ‘s a chuireas iad casg air bacadh magnetach a dh’ fhaodadh droch bhuaidh a thoirt air cruinneas sgrùdaidhean magnetach.Tha e air a dhèanamh de stuth sònraichte stàilinn le ìosal permeability, àrd meacanaigeach feartan agus nas fheàrr an aghaidh corrach sgàineadh.
Bidh sinn a’ toirt seachad coilearan drile slick, coilearan drile shnìomhanach agus coilearan drile neo-magnetach;tha na meudan aca bho 3-1/8 gu 11 òirleach.A bharrachd air na coilearan drile sa chlàr gu h-ìosal, is urrainn dhuinn coilearan drile eile a thoirt seachad air iarrtas luchd-ceannach.

Tha coilearan drile nan co-phàirt trom-dhleastanais a tha air an togail bho bhàr cruaidh de stàilinn alloy atharraichte AISI 4145H.?Tha na coilearan drile àbhaisteach againn a’ faighinn suidheachadh crìochnachaidh uachdar “cho rolled”.Bidh a h-uile bàr àbhaisteach a’ faighinn làimhseachadh teas a bheir dhaibh na feartan meacanaigeach riatanach.
Tha na bàraichean an uairsin air an trepaned agus air an gluasad.?Tha na coilearan drile againn uile air an dèanamh a-steach
a rèir API spec 7, Q1 agus cleachdadh 7G a thathar a’ moladh, mar a tha iomchaidh.
