Drilling Casing Pipe Oil Drill Pipe Mud Scraper 2" To 5 1/2"
1. Oil drill pipe mud scraper
Working principle: The mud scraper on the outer wall of the drill
pipe mainly adopts the slide way to centralize the mud scraper, so
that the mud
scraper slides along the slide way. Under the action of the
double-acting cylinder and the spring, the mud scraper is tightly
attached to the annular
outer wall of the drill pipe lifted upward from the well. The mud
scraper scrapes off the drilling fluid on the outer wall of the
drill pipe lifted upwards,
so that the outer wall of the drill pipe column lifted out is
clean, and there is no drilling fluid to pollute the environment.
2. Detailed description Material:
This product uses excellent wear-resistant nitrile rubber as the
basic material, and there is a skeleton inside to
prevent deformation. Main application: It is used to prevent the
mud from spraying out when the drill pipe is tripped, which is
convenient for
operation and ensures safety; it can prevent the drilling fluid
from returning from the drilling and the drilling fluid on the
inner wall of the drill pipe to
prevent the corrosion of metals.

Using RSS3, JSR, SBR raw materials. It has the characteristics of
wear resistance and mud erosion resistance. Use temperature
-30℃-120℃,
It is installed under the turntable to scrape off the mud and oil
on the surface of the drill pipe during tripping, which is
conducive to mud collection
and prevents debris on the drilling floor from falling into the
wellhead.
