Directional Drilling Blades
Directional drilling trenchless pipe laying is the mainstream method of trenchless pipe laying technologies. Generally the drilling of directional hole is first carried out and then is reaming, which is a vital process with much works. The shorter time reaming process takes, the safer the drilling and higher the pipe laying efficiency and the better the economic benefits. Therefore, it's vital to choose suitable backreamers according to different strata.
Directional drilling blade is a component of directional drilling bit, so uses should choose the shapes of drilling blades according to different strata. Generally when the stratum is hard, the cutting edges should be cone shaped and when the stratum is soft or intact, the cutting edges can be wide shaped. The strength and wear resistance of drilling blades determine the boring speed and efficiency of pilot holes.
Operations and attentionsConstruction of directional drilling should be carried out according to standardized operation processes. Meantime, construction technologies should be changed in time according to specific stratigraphic conditions to ensure the normal use of products and prolong the service life of drilling blades.
Product maintenanceCheck carefully each time using the product, mainly check if there is any defect or fracture. If there exist these conditions, repair in time.
Technical parametersThe directional drilling blades produced in our factory have specifications of φ100, φ120 and φ150.
Package and transportationPackage method: Generally, the product is wrapped with plastic foam outside the surface and then bulk packaged. Packing boxes can be used if there are special requirements.
