The API Vacuum Insulated Casing/tubing from Dongying Lake Petroleum Technology Co., Ltd employs advanced thermal insulation technologies to maintain temperature stability in high-temperature oil and gas wells. It integrates prestress compensation to ensure mechanical reliability under extreme conditions, while vacuum pumping, heat reflection, and thermal convection techniques combine to deliver superior insulation performance. This design minimizes heat loss, enhances energy efficiency, and improves safety in thermal recovery operations.
The tubing is typically constructed from high-strength alloy steel, with an outer casing and inner tubing separated by a vacuum-sealed annular space. The vacuum layer eliminates conduction and convection heat transfer, while reflective coatings and radiation shields further reduce heat loss. Standard outer diameters range from 2-7/8" to 4-1/2", with wall thicknesses and grades selected based on well depth and pressure requirements.
This product is used in steam-assisted gravity drainage (SAGD) and other thermal enhanced oil recovery (EOR) projects where maintaining steam temperature is critical. Buyers include oil and gas producers, thermal recovery service providers, and engineering firms. Confirm the exact thermal performance ratings, material grades, and compatibility with your well design before ordering. The tubing is typically shipped in standard lengths with protective packaging to prevent damage during transit.

Before placing an order, verify the thermal performance ratings, including maximum temperature and insulation efficiency, to ensure compatibility with your steam injection or thermal recovery project. Request material certifications and API compliance documentation to confirm the tubing meets industry standards for strength and durability. Discuss customization options, such as specific outer diameters or connection types, if your well design requires non-standard specifications.
Clarify the lead time for manufacturing and delivery, as vacuum insulated tubing often involves specialized production processes. Agree on Incoterms such as FOB or CIF to define responsibilities for shipping, insurance, and import duties. Payment terms, including progress payments or letters of credit, should be negotiated upfront to align with your procurement policies.
Upon delivery, inspect the tubing for signs of damage, particularly in the vacuum-sealed annular space and threaded connections. Request a vacuum integrity test report to confirm the insulation layer remains intact. For critical applications, consider third-party inspection to validate thermal performance and structural integrity before installation in the well.
