China Standard 2022 Factory Price Steel Pipe API 5D 5dp 5-1/2 Drill Collar Heavy Weight Drill Pipe for Oil Well with high quality

Product Description

As an important part of drill string, drill collar can supply the drill bit and increase the rigidity of drill string. Dril collar are manufactured strictly according to API Spec7-1 standard with material of AISI 4145 Mod. We supply slick drill collars, spiral drill collars, etc. The size of drill collar we can provide is from 3.1/8 to 11 inches. We can also provide other drill collars at customers’ specific request .

Drill Collars are 1 of the parts of a drills string. Drill for the Collars is meant to provide weight for drilling purposes. The Drill Collars are thick walled tube like pieces that are machined from CZPT steel bars, although they are often made from plain carbon steel or the non magnetic alloy of copper and steel or other premium alloys that are non magnetic in nature. Drill collar has bars of CZPT steel that are drilled from 1 end to the other to provide a passage for pumping the drilling fluids through the collar.

Collars that are available for drilling have an external diameter that is made of steel and can be slightly machine perfected for making sure of the roundness. Drill Collars are sometimes perfected with the help of spiral Collars or helical shaped grooves. Drill threaded collar have connections that are male or 1 end and female on the other and. These are cut into a multiple collar that can be adjusted with screw along with other down hole tools. Drill helps make a bottom hole assembly or BHA.

Drill collars are extra-heavy integral tools used to concentrate weight CZPT the drill bit so as to produce sufficient force for the drill bit to break rock efficiently while drilling. They are made of AISI 4145H modified steel and are connected between drill pipes and drill bits.

Drill collars come in 30 or 31 foot lengths and are furnished as slick (as-rolled surface finish) or spiraled. Spiraled drill collars have grooves on its external surface which maintains an even flow of drilling fluid around the collar to equalize pressure and reduce differential-sticking of the collar to the wall of the oilwell.

Our drill collar connections comply with dimensional requirements specified in API Spec. 7/7-1 and guidelines presented in API RP7G. Drill collars also come with slip and elevator recesses for safe and efficient handling. Slip and elevator recesses can be used together or separately and are machined in compliance with API RP7G guidelines unless otherwise specified.

Can I find information on the materials and coatings used in manufacturing steel collars?

Yes, you can find information on the materials and coatings used in manufacturing steel collars. Manufacturers and suppliers typically provide details about the materials and coatings used in their collar products. Here’s some information regarding materials and coatings commonly used in the manufacturing of steel collars:

  • Materials: Steel collars are primarily made from various types of steel. The specific grade of steel used can vary depending on factors such as load requirements, environmental conditions, and cost considerations. Common types of steel used for manufacturing steel collars include carbon steel, stainless steel, and alloy steel. Carbon steel collars are often cost-effective and offer good strength but may be susceptible to corrosion. Stainless steel collars provide excellent corrosion resistance but may have lower load capacities compared to carbon steel. Alloy steel collars offer a balance of strength and corrosion resistance and are often used in demanding applications.
  • Coatings: Coatings are sometimes applied to steel collars to enhance their performance and protect against corrosion. Some common types of coatings used in manufacturing steel collars include:
    • Zinc Plating: Zinc plating is a common coating that provides a sacrificial layer to protect the steel collar from corrosion. It offers good corrosion resistance and can be applied in various thicknesses depending on the level of protection required.
    • Black Oxide: Black oxide coating is a chemical conversion coating that provides a black finish to the steel collar. It offers some corrosion resistance and can also improve the collar’s appearance.
    • Passivation: Passivation is a process that removes surface contaminants from stainless steel collars and enhances their corrosion resistance. It helps to form a passive oxide layer on the surface, providing protection against rust and corrosion.
    • Electroplating: Electroplating involves depositing a thin layer of metal, such as chrome or nickel, onto the surface of the steel collar. Electroplating can provide enhanced corrosion resistance, improved aesthetics, and increased durability.
    • Powder Coating: Powder coating is a process where a dry powder is electrostatically applied to the steel collar and then cured under heat, creating a hard and durable finish. Powder coatings offer excellent corrosion resistance, impact resistance, and color options.

When seeking information about materials and coatings used in steel collars, it is recommended to consult the manufacturer’s documentation, product datasheets, or reach out to the manufacturer or supplier directly. They can provide specific details about the materials and coatings used in their collar products, including any certifications or industry standards they adhere to.

By understanding the materials and coatings used in the manufacturing of steel collars, you can make informed decisions and select collars that are suitable for your application’s requirements and environmental conditions.

What are the key features to consider when selecting a steel collar for a specific shaft?

When selecting a steel collar for a specific shaft, there are several key features to consider. These features will help ensure that the collar is compatible with the shaft and meets the requirements of the application. Here are the key features to consider:

  • Shaft Diameter: The most critical feature to consider is the shaft diameter. The steel collar’s inner diameter should match the shaft diameter precisely to ensure a proper fit. Measure the shaft diameter accurately and select a collar with an inner diameter that matches it.
  • Material: Consider the material of the steel collar. It should be compatible with the environmental conditions and the materials it will come into contact with during operation. Common materials for steel collars include carbon steel, stainless steel, and alloy steel. Each material has its own properties in terms of strength, corrosion resistance, and temperature tolerance.
  • Width and Thickness: The width and thickness of the steel collar are important factors to consider. The width should be sufficient to provide stability and support to the shaft, while the thickness should be suitable to handle the applied loads. Consider the required load capacity and the space available on the shaft when selecting the appropriate width and thickness.
  • Mounting Method: Steel collars can be mounted using various methods, such as set screws, clamping screws, or split designs. Consider the mounting method that is most suitable for your application. Set screw collars use screws to secure the collar onto the shaft, clamping screw collars use screws to tighten the collar around the shaft, and split collars can be easily installed and removed without the need for complete disassembly.
  • Special Features: Depending on the application requirements, you may need to consider special features of the steel collar. This could include keyways, tapped holes, or threaded bores for attaching additional components or accessories. Evaluate if any special features are necessary for your specific application.
  • Surface Finish: The surface finish of the steel collar can impact its durability and resistance to wear. Consider factors such as smoothness, hardness, and any protective coatings or treatments applied to the collar’s surface. These factors can affect the collar’s performance and resistance to factors like corrosion or abrasion.
  • Manufacturer’s Specifications: Finally, refer to the manufacturer’s specifications and guidelines for the steel collar. Manufacturers provide detailed information about the collar’s design, load capacity, torque values, and other relevant data. Ensure that the collar meets the manufacturer’s recommendations and guidelines for your specific application.

By considering these key features, you can select a steel collar that is compatible with your specific shaft and meets the requirements of your application. It’s important to consult with the manufacturer or a knowledgeable supplier for further guidance and to ensure optimal selection and performance.
