Import Api Casing Guiding Float Collar Float Shoe — Buy in wholesale FOB from Supplier in China

The Api Casing Guiding Float Collar Float Shoe from Dongying Lake Petroleum Technology Co., Ltd combines casing guidance with controlled flotation for cementing operations in oil and gas wells. The guiding geometry at the shoe nose reduces hang-up on borehole ledges and washouts during casing run-in, while the integrated float collar provides back-pressure isolation during cement displacement. The source indicates API standard construction and compatibility with various casing sizes, though buyers must confirm exact dimensional and performance parameters directly with the supplier.

Material construction targets API casing accessory grades, with typical bodies machined from seamless mechanical tube or forged bar stock in grades compatible with J55 through P110 casing programs. The guiding nose profile usually features a rounded or bullet-nose form with hardfacing or carbide insert protection for abrasive formations, though specific hardfacing alloy and thickness require supplier confirmation. The sealing mechanism relies on a back-pressure valve, with spring or differential pressure actuation common in this product class. Standard elastomer compounds for valve seals include nitrile for conventional service and fluorocarbon for elevated temperature applications, but the exact seal specification and temperature de-rating curve must be requested from the manufacturer.

Drilling contractors and operator companies deploy this equipment in primary cementing of production casing, surface casing, and intermediate strings across vertical and deviated well profiles. The guiding function proves particularly valuable in directional wells where doglegs and ledge formation increase casing string mechanical risk. The float collar component enables casing flotation to reduce hook load, with the back-pressure seal preventing cement fallback after displacement. Buyers should confirm with Dongying Lake Petroleum Technology Co., Ltd the full casing size compatibility matrix, thread specification, valve actuation mechanism, and whether the design is rated for standard or high-pressure high-temperature service conditions.

Dongying Lake Petroleum Technology Co., Ltd is located on Huanghe Road, Dongying, Shandong Province, China, within a regional hub for petroleum equipment manufacturing and oilfield services. The supplier holds imported tier and harbor trust designations. The zero percent response rate and zero recorded average response hours suggest no platform-mediated communication history, so buyers should plan for direct outreach and extended follow-up cycles when initiating procurement discussions.

The company markets API-standard casing guiding float collar and float shoe products with emphasis on drilling efficiency and cementing performance. The available source profile does not disclose establishment year, facility size, employee count, annual turnover, specific API licence numbers, named clients, or completed project references. Buyers are advised to request formal evidence of API monogram authorization, ISO 9001 or API Q1 quality management certification, and product-specific test records. The Dongying location provides access to established supply chains for raw materials and machining services, with export logistics potentially routed through Qingdao or Tianjin, though specific freight arrangements and export experience require direct confirmation from the supplier.
