YG Drill Pipe For Sale Introduction
Drill Pipe for sale also called Drill Rod. The drill pipe is a steel pipe with a thread on the tail. The drill rod is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending, and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used many times.
Drill rods are divided into three categories: kelly rods, round drill rods, and heavy drill rods. The connection sequence is kelly (1) + drill pipe (n pipes, determined by the depth of the well) + weighted drill pipe (n, determined by the design of the drill tool assembly). YG Drill Equipment company has different types of drill pipes for sale. Please feel free to leave your requirement.
Drill Stem Specifications
According to the American Petroleum Institute (API), there are three categories of drill pipes according to length (L).
First: 5.486 to 6.706m (18 – 22ft).
Second: (commonly used): 8.230 -9.144m (27 – 30ft).
Third: 11.582-13.716m (38 – 45ft).
Drill rods can also be classified by outer diameter size. Commonly used drill rod sizes (D): 88.9mm, 114.3mm, 127mm.

Drill Pipe Production Process
Smooth pipe and original steel pipe are made into drill pipe after many processing steps. First, through the steel pipe thickening process, the smooth pipe surface is bent inward. And the steel pipe wall is thickened. Next, the thread is machined and plated with copper which can increase its strength. Then the non-destructive quality control inspection was carried out. And then, the welding of the steel pipe body joint was carried out. Then, the pipe will undergo welding heat treatment and welding of final treatment to eliminate welding residual stress. Contact us to get more details about the YG drill pipe for sale.
Before painting and packaging the finished drill pipe, other tests should be carried out on the finished pipe, including hardness test, pressure test, and non-destructive test. The length of the drill pipe is generally about nine meters. Of course, if you have other length drill pipe requirements, please tell us.

Steel Grade And The Strength Of Drill Rod
The steel grade of the drill pipe refers to the grade of the drill pipe steel. It is determined by the yield strength of the drill pipe steel. API (American Petroleum Institute) divides drill pipe steel grades into five grades: D, E, 95(X), 105(G), and 135(S). The higher the drill pipe steel grade, the greater the yield strength of the pipe. The various strengths of the drill rod will be greater. In the strength design of the drill string, it is recommended to increase the strength of the drill string by increasing the steel grade instead of increasing the thickness of the wall.

Drill Pipe Joint
The drill pipe joint is a component of the drill pipe to connect the two ends of the drill pipe body. In order to enhance the connection strength of the joint, we will increase the wall thickness of the pipe body at the joint. According to the way of thickening, there are three forms: inner thickening, outer thickening, and inner and outer thickening.
There are threads (thick buckles) on the joints to connect each single drill rod. The thread of the drill pipe joint is a tapered pipe thread with a sealing shoulder. The shoulder surface is tightened to play a sealing role. And the thread only plays a connecting role. Different thickening methods have different thread buckle types for corresponding joints. According to the threaded buckle type drill pipe joints, there are four types. Internal flat (IF), flat-hole (FH), regular (REG); digital (NC).
