Screw Flights

 

The largest and professional screw flight manufacturer, with patents for spiral manufacturing process.

Backed with three manufacturing technology to produce the different types including Continuous Cold Roller Screw Flight, Sectional Screw Flight and Continuous Equal Thickness Screw Flight which almost meet all the market demand on the types and sizes.

Equipped with 23 screw flight forming machines, we have an annual production capacity up to 7000 tons.WIDE A
 

Sectional / Segmented Auger Flights

FEATURES

• A proprietary process coming into its own when material type, material thickness, big diameters, hard controlled special gauge are considerations and cannot be accomplished by conventional continuous rolled forming process
• A single pitch construction with consistent cross sectional thickness between inner and outer edges. Every screw flight section is formed accurately up to the customer's size.
• A wide range of sizes up to 2000 mm in diameter, 40 mm in thickness, and 1500 mm in pitch are available
• Ribbon, Tapered and Variable Pitch Flights are available on application. Flights can also be hard faced or coated with wear protection materials
• High precision, with no minimum order quantity requirement and customized size can be met.

 

MATERIALS

Carbon Steel, Low Alloy Steel, Wear Resistant Steel, Stainless Steel, etc.

 

SPECIFICATIONS

Any Screw flight with size coming in the range of the following table can be made. 

 

P--Pitch, D--Do, d--ID, T--Thickness

 

Continuous Cold Rolled Screw Flights

FEATURES

·Continuous equal thickness is another proprietary process patented and developed by our own in-house engineers with the purpose of overcoming problems like difficult forming, material wastage for small lot production.
·Continuous formed pitch construction with consistent cross sectional thickness between inner and outer edges, high precision, high output and high material usage.
·Manufactured in the same fashion as the screws manufactured by continuous cold rolled forming methods with the difference being consistent material thickness from inner to outer edge of the screw flight.

• High accuracy, low material wastage
• Smooth surface finish and good rigidity, easy to weld and assemble

 

MATERIALS

Carbon Steel 

Any screw flight with size coming in the range of the following table can be made.

SPECIFICATIONS

Note:

When the inner diameter is within the range of Min. +5mm, then the max. O.D. should not exceed the triple of I.D.

Minimum order quality of 15 tonnes exists for custom manufactured Continuous Screw Flights if the thickness required is not listed in above chat.

Core Barrel&Overshot

Drilling tool assembly (P, H, N and B)
Relevant description of products:
Retrieve the inner tube with an overshot without lifting out the whole rods string to obtain the core, the wireline coring system lifts the underground core sample out of the borehole through the overshot to take back the entire inner tube and conduct sampling analysis. This improves productivity of the work site and guarantees safety of core sample during drilling down.
The system is realized through a fully independent inner tube. During its working, the inner tube does not connect with the overshot but locates at the bottom of the coring Drilling Rod directly (behind the coring drilling bit). An assembly device is installed on top of the inner tube, which includes coring and recycling functions. When the inner tube is full of core sample, the overshot is placed to the bottom from the borehole through a steel wire rope and lifted out by a winch. After the inner tube assembly is lifted to the surface, an empty inner tube is placed to the bottom of the hole to recover the drilling. This improves well drilling efficiency.
Our company provides core barrel assmeblies of different diameters to meet customers' demands. The wireline coring system is applicable for most drilling conditions and standard DCDMA hole sizes (B, N, H and P).
Currently, the company provides two models of wireline coring systems: double-tube and triple-tube
Core barrel assembly: It consists of inner tube and outer tube groups.
The inner part consists of the following parts: spearhead assemly, retrival components, core sample collection component, landing shoulder, stop ring and other parts.inner tube group, independent from outer tube group, collects core sample sample during well drilling.
The outer tube part consists of parts , which includes locking coupling, adapter coupling, outer tube, etc. The outer tube group that is kept at the bottom of the hole all the time holds the inner tube assembly during drilling.
The triple tube coring system AU3 has the same components as the dual-tube. And its interior has a third tube that is known as liner tube of the inner tube.
Liner tube of the inner tube is placed in the inner tube. The triple tube system can realize overall recovery ratio of core sample when drilling stratum with coal, clay or bigger crack. The liner tube or split tube keeps the core sample at its receiving status to collect or load and store easily.
Only N, H and P sizes are available for the triple tube coring system.
