Julat Panjang Paip Gerudi:
Julat 1: 18 kaki hingga 22 kaki.
Julat 2: 27 kaki hingga 30 kaki.
Julat 3: 38 kaki hingga 45 kaki.
Jenis Paip Gerudi:
Paip gerudi
Paip gerudi berat

Paip gerudi:
Digunakan untuk menghantar kuasa (tork dan ketegangan) dan mengangkut bendalir penggerudian, menyambungkan pelantar penggerudian tanah dan alat penggerudian lubang bawah. Paip gerudi berat ialah paip penggerudian-berat sederhana, Ia mempunyai ketebalan dinding yang lebih besar daripada paip gerudi biasa dan lebih kecil daripada kolar gerudi.
Kecelaruan paip gerudi:
Kecelaruan (benang-penamat hujung) merujuk kepada dinding sambungan alat pada sambungan berulir. Paip gerudi ditawarkan dengan gangguan dalaman (IU), gangguan luaran (EU) atau gangguan-luaran dalaman (IEU).
IU- Dalam gangguan dalaman, peningkatan ketebalan di sepanjang dinding bahagian dalam mengimbangi logam yang dikeluarkan dalam benang dengan dinding luar yang seragam dan lurus.
EU- Dalam gangguan luaran, peningkatan ketebalan di sepanjang diameter luar tiub mengimbangi logam yang dikeluarkan dalam belitan dengan lubang lurus.
IEU- Dalam-tebal gangguan luaran ditingkatkan di sepanjang kedua-dua dinding dalam dan luar paip untuk mengimbangi logam yang dialihkan dalam benang.
Kolar gerudi:
Digunakan untuk memberikan tekanan bit (WOB), menstabilkan mata gerudi dan mencegah sisihan telaga, terletak di bahagian bawah rentetan gerudi.
Kolar gerudi:
