Drilling tools
1.Special tools for geological drilling
The
special tools for geological drilling are widely used in ascertaining
underground rock structures,underground water, natural gas and mineral
resources.The exploitation of petroleum and natural gas cannot be taken
without drilling wells,and the seamless pipe is the main tools,they
generally include core external pipe with,core internal pipe,casing pipe
and drill rod,etc.Our drilling tools for these applications have
complete specifications and high quality.
2.Coal mining bits
The
cutter pick is used in exploiting mines and tunneling work of
lanes,tunnels,and these projects are mainly equipped with coal
cutter,heading machine and milling machine,etc.
The cutter picks
produced by our company include the following types:
U62、U47、U82、U84、U85,U92、U94、U95、S100、S120、S135、S150、S170 and so on.The
pick body is formed by low-temperature extrusion work with quality
materials.It has high density and will not eliminate carbon.The NC
machine can guarantee precision of the size and also apply special
processing and anti-wear materials.
Anchor rope anchor rod
The
high-intensity under-relaxation anchor wire produced by our company can
be used in cable-stay bridge,steel-arch bridge,suspension bridge,side
slope adjustment and water project.The anchor wire specification is wire
number 37-421 with maximum nominal breaking load reaching 25484KN.it
has been already applied in many bridge constructions an home and abroad
such as WUHAN Baishazhou Yangtze Bridge,jinzhou yangzte Bridge,Junshan
Yangtze Bridge,Badong Yangtze Bridge,Fengjie Baiyian No.3 Bridge and
Burma Bridge,etc.
The high intensity alloy steel anchor bolt
produced by our company is comprehensively applied in
road,railway,tunnel constructions,water projects and pipe roofing
support,side lope support.It is the most economic and effective way of
improving rock stablilty and solving complicated stabilization issues in
geotechnical engineering.The specs of self-drilling cavity rock
bolt,hollow grouting bolt and small tubes provided by our company cover
full range and series used in China and overseas.It has already been
applied in many national major constructions such as highly dangerous
side slope adjustment in Three Gorges Project,diversion tunnel
construction in jinpin Power Plant,Wuhan-Guangzhou railway,deep
foundation pit construction of Wushang Mansion and exported to countries
and areas like U.S.A,Canada,Australia and Europe.
