Best quality api 7-1 standard and sprial drill collar

Product description
Drill collar is the basic component in the bha which provide weight on the bit for dirlling and keeps the drill string in tension.Drill collar is manufactured from aisi 4145h modified quenched and tempered steel and is heat treatment along its entire length for uniform toughness and durability. Srict netallurgical test are performed pre specifications to ensure that the heat treatment produces consisitent and maxium hardness through the depth of the bar.
Feartures and benefits:
1. Hardness rannge of 285 to 341 bhn and a charpy impact value of 40ft/lbs are guaranteed for evenly distributed 16 points in any cross sections at room temperature
2.Connections ar phosphate coated afther machinning to protect the threads from corrosive elements and to prevent galling upon initial make -up
Thread roots are cold rolled on api and h0-90 connections
3.Pressed steel thread protectors are supplied fo all drill collar that are equipped with standard connection

We supply slick drill collars, spiral drill collars and non-magnetic drill collars; their sizes are from 3-1/8 to 11 inches. Besides the drill collars in the table below, we can supply other drill collars at customers' request.


Materials:
Drill collars are manufactured from AISI 4145H modified steel, and are supplied in the "as rolled" surface finish condition. Alternative surface finishes are available.

Trepanning and Heat Treatment:
Drill collars are trepanned and drifted to API Spec 7-1. Full-length heat-treatment processes ensure that mechanical properties meet or exceed API Spec 7-1 requirements. A hardness range of 285-341, Brinell hardness and Charpy "V" notch minimum impact strength of 40 ft-lb at 70 F are guaranteed one inch below the surface.

Traceability:
Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies.

Rigid Inspection Procedures:
We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar.

Cold Rolling:
Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation.

Phosphate-coated or Copper Plating:
All connections are phosphate-coated or copper plated to improve resistance to corrosion.

Slip Groove, Elevator Groove and Size:
Lake offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines.

Thread Protectors:
Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.

We supply slick drill collars, spiral drill collars and non-magnetic drill collars; their sizes are from 3-1/8 to 11 inches. Besides the drill collars in the table below, we can supply other drill collars at customers' request.
