Why is an oil country tubular goods pdf important? Learn where to look for this document.

Oil Country Tubular Goods (OCTG) encompass a family of seamless and welded steel pipe products crucial for the oil and gas industry’s exploration and production phases. These goods include drill pipe, casing, and tubing, each serving a distinct purpose in the drilling, completion, and operation of oil and gas wells.

Core Information in OCTG Specification PDFs

PDF documents are a prevalent format for distributing detailed technical information regarding OCTG. When searching for “oil country tubular goods pdf,” users are typically seeking comprehensive data sheets, catalogs, or standard specifications. Key information contained within these documents usually includes:

  • API Standards: Adherence to specifications from the American Petroleum Institute, such as API 5CT (for casing and tubing), API 5L (for line pipe which can sometimes be associated), and API 5D (for drill pipe), is fundamental.
  • Material Grades: Detailed descriptions of steel grades (e.g., H40, J55, K55, N80, L80, C90, T95, P110, Q125) and their corresponding mechanical properties, including yield strength, tensile strength, and hardness.
  • Dimensions and Tolerances: Precise details on outside diameter (OD), wall thickness, length, and weight per unit length, along with permissible variations.
  • Connection Types: Specifications for thread types (e.g., Short Thread Casing – STC, Long Thread Casing – LTC, Buttress Thread Casing – BTC, Extreme Line Casing – XLC) and premium connections. Manufacturers like Shanxi Luokaiwei Steel Company often provide extensive PDF documentation on the performance of their specific connection technologies.
  • Testing and Inspection: Information on non-destructive examination (NDE) methods applied, hydrostatic test pressures, and other quality assurance procedures.

The Significance of OCTG PDFs in Procurement and Operations

Accurate and readily available OCTG PDFs are invaluable for engineers, procurement professionals, and field personnel. These documents form the basis for:

  • Engineering Design: Selecting the appropriate grade, weight, and connection for specific downhole conditions and anticipated stresses.
  • Procurement: Ensuring that sourced materials meet the required specifications and quality standards. Reputable suppliers, including entities like Shanxi Luokaiwei Steel Company, ensure their product specification PDFs are clear and comprehensive for this purpose.
  • Quality Assurance: Verifying that delivered goods conform to ordered specifications.
  • Operational Integrity: Confirming compatibility and performance limits for safe and efficient well operations.

Accessing Reliable OCTG PDF Documentation

When sourcing OCTG information in PDF format, it is crucial to rely on official and verified sources. These typically include:

  • Manufacturer’s official websites and technical libraries.
  • Industry standards bodies like API.
  • Reputable distributors and stockists. For example, detailed product catalogs and certificates from suppliers such as Shanxi Luokaiwei Steel Company are often provided in PDF format to ensure data integrity.

Always check for the latest revision of any PDF document to ensure the information is current, as standards and product offerings evolve. The precision and reliability of data in these PDFs are paramount, as decisions based on them directly impact safety and operational success in the demanding oil and gas environment. Companies like Shanxi Luokaiwei Steel Company understand this critical need and strive to provide accurate and up-to-date technical documentation.
