FAQ
1. How to get an exact quotation?
Answer: Please send us detailed information as below:
-Tricone bits(Diameter, IADC code)
-PDC bits(Matrix or Steel body, blades quantity, cutter size, etc)
-Hole opener(Diameter, size of pilot hole, hardness of rocks, thread connection of your drill pipe, etc.)
-Roller cutters(Diameter of cones, model number, etc.)
A simple way is sending us photos .
Besides above, if possible please provide more information as below:
Drilling depth in vertical well drilling, Drilling length in HDD, hardness of rocks, Capacity of drill rigs, application(oil/gas well drilling, or water well drilling, or HDD, or foundation).
Incoterm: FOB or CIF or CFR, by plane or ship, port of destination/discharge.
The more information provided, the more exact quotation will be offered.
2. About lead time,payment terms, delivery ?
Answer: We always have regular models available in stock, prompt delivery is one of our advantages. Mass production depends on quantity of order.
We accept all regular payment terms including L/C, T/T, etc.
We are near from Beijing airport and Tianjin(Xingang) seaport, transportation from our factory to Beijing or Tianjin only takes one day, fast and very economical inland charges.
