5 Things to Know Before Buying pipe floats

Important Facts About Your Drilling Pipe

There are various types and classifications of drilling pipes, each differing in their construction, properties, and applications. Offshore drillers must understand these differences to select the most appropriate type for their operations.

This post will discuss the different types of drilling pipes and their uses, highlighting factors to consider when choosing a drilling pipe for your project.

Without drills and drill pipes, there is no petroleum extraction. These tempered, hollow steel pipes are crucial in the drilling industry, pumping drill fluid to the drill bit, enduring extreme subterranean pressures.

Drilling Pipe Classification

After a thorough check with spherometers, drill pipes are classified into three categories:

N-class pipe (New Pipe)

The strongest and newest pipe available, usually in pristine condition.

P-class pipe (Premium Pipe)

These pipes have endured some wear but still function very capably.

C-class pipe

Includes C-1, C-2, and C-3 classifications for well-worn pipes nearing the end of their useful lives.

Once pipes reach the end of their service life, they are graded for scrap, denoted with red bands. Due to the high cost, drill pipes are often reused and sold, both new and used, until they are no longer functional.

Types of Drilling Pipe

Having covered the basics, let’s delve into the several types of drill pipes available.

Drill String

The drill string encompasses the entire column of tools, including the drill pipe, shaft collar, tools, and drill bit. Made from tempered steel, sections of drill pipe rarely exceed 30 to 33 feet in length due to cost and transport reasons. Extreme depths involved in drilling necessitate connecting sections with tool joints—one section with a male connection is paired with a female connection.

Drill pipes come in various thicknesses, such as 2 ⅜ inches, 5 inches, and 6 ⅝ inches. For more steel reinforced pipe information, please contact us. We will provide professional answers.

Pipes in the upper parts of the drill string differ in thickness and construction from heavyweight drill pipe (HWDP), used as transitions between drill collars and regular, thinner pipes.

Heavyweight Drill Pipe (HWDP)

HWDPs are stronger than regular drill pipes, designed to handle added pressures and stresses during transitions between drill collars and regular pipes. Preferred for their flexibility, these pipes range in diameter from 3.5 inches to 6 ⅝ inches, weigh almost twice as much lb/ft as regular pipes, and have tensile strengths from 200,000 lbs to over 1,000,000 lbs.

Equipped with center upsets or wear pads, HWDPs prevent exterior grinding against rough bedrock, prolonging their lifespan. While drill pipes come in various sizes, diameters, and materials, they fall into two broad categories: regular drill pipes and HWDPs used as transitions. Most pipe types can be bought new or used and are graded into three broad categories (N, P, and C, with three subdivisions for C).

Oilfield equipment like drill pipes and OCTG must endure significant stress during drilling, necessitating regular inspections by Field Service Supervisors to ensure safety and performance.

Five Things to Know Before Buying Pipe Floats

Understand Your Project Requirements

Before purchasing pipe floats, evaluate your project needs comprehensively. Determine the specific applications, environmental conditions, and load-bearing requirements to choose the appropriate pipe float material and size.

Material and Durability

Check the material's quality and durability. HDPE is often recommended due to its resistance to corrosion, impact, and UV degradation. For projects involving abrasive materials, a robust material choice is crucial for longevity and performance.

Floatation Capacity

Ensure the pipe floats have adequate buoyancy to keep the dredging pipeline afloat under all operational conditions. Buoyancy calculations should consider the pipeline's weight and additional external forces like waves and currents.

Ease of Installation and Maintenance

Choose pipe floats that are easy to install and require minimal maintenance. Modular designs can simplify installation and adjustment while reducing downtime. Maintenance-friendly features will save time and costs in the long run.

Compliance and Certifications

Verify that the pipe floats meet industry standards and regulations. Compliance ensures safety, reliability, and performance. Certifications from recognized bodies attest to the product's quality and suitability for your applications.
