Kubowola mipope chimagwiritsidwa ntchito migodi, kufufuza nthaka ndi mitundu yonse ya pobowola (madzi, mafuta, mpweya, etc) project.As kutsogolera kubowola chitoliro kupanga, timapanga mitundu yonse ya mfundo ndi mipope sanali muyezo kubowola kwa makasitomala athu.Mapaipi athu obowola kuphatikiza chitoliro chobowola chitsulo, chitoliro chobowola migodi, chitoliro chobowola madzi, chitoliro chobowola mafuta, chitoliro chobowola API, ndodo yobowola DTH, ndodo yobowola waya, ndi zina.

Zofunikira za chubu chapamwamba cha DTH ndikukhazikika, kulondola komanso kuwongolera.

 Kubowola Chitoliro :

1.Pipe thupi: ozizira kujambula chitoliro seamless.kotero chitolirocho chimakhala ndi kukula kolondola, chabwino chapakati.
2.Zakuthupi za thupi la Pipe ndizofanana ndi Sandvik.
3.Thread cholumikizira:Kutentha ndi nayitrogeni mankhwala, kotero chitoliro ndi cholimba kwambiri ndi zosavuta kutsegula ndi kutsitsa.
4.Friction kuwotcherera.

Standard DTH kubowola chitoliro:
