Float collar
The Float collar is a critical component placed above the Float Shoe in drilling casing strings, designed to stop reverse flow during cementing operations. It is fabricated from industrial‑grade steel that can endure high pressures and temperatures typical of offshore and on‑shore drilling environments. The collar’s design incorporates a sealed bearing assembly that permits smooth passage of cement slurry while maintaining a secure seal under load.
In the oilfield market, float collars are often manufactured to API 5CT specifications, with typical pressure ratings up to 10 000 psi and temperature limits of 150 °C. The material is usually carbon steel or alloy steel treated to resist corrosion from drilling fluids; the listing notes a “durable material” but does not specify the exact grade, so buyers should request the precise steel specification. Standard dimensions include a nominal outer diameter of 4 inches and a length of 150 mm, which aligns with common casing sizes used in well construction.
The primary customers are drilling contractors, well‑service companies and EPC firms that require reliable cementing tools. The supplier mentions flexible MOQ and offers FOB or CIF shipping, allowing purchasers to adjust order size to project needs. Certification claims refer to compliance with industry standards; buyers are encouraged to obtain the relevant test certificates before finalising a contract.

Sourcing Float collar from Dongying Landdrill Oilfield Supply Co., Ltd - China Import Guide
Confirm the exact steel grade, pressure rating and dimensional data before issuing a purchase order. Request the API 5CT test report and any other quality certificates to verify that the collar meets the required mechanical properties for your well design.
Discuss logistics early: ask the supplier which Incoterms they can provide (FOB from the port of Qingdao or CIF to your destination), the anticipated lead time after order confirmation, and acceptable payment methods such as T/T or L/C. Shipping schedules can be affected by seasonal port congestion, so align delivery windows with your drilling program.
Plan a pre‑shipment inspection that checks material composition, dimensional tolerances and thread integrity. Arrange for a third‑party agency to issue a test report and provide a packing list, material safety data sheet and certificate of conformity before the cargo departs the factory.
