Double Metal Cylinder Liners
The double metal cylinder liner offered by Dezhou Boru Petroleum Machinery Manufacturing Co., Ltd consists of a forged steel outer shell and a high‑chromium iron inner sleeve. The outer shell is produced from carbon steel by hot‑press forming, delivering a tensile strength exceeding 900 000 psi. The inner sleeve is cast from a high‑chromium alloy and provides abrasion resistance and corrosion protection suitable for severe operating conditions. Dimensional accuracy is tightly controlled during production, ensuring straightforward and stable installation, while the finished hardness and surface finish give the inner sleeve a service life of more than 800 hours.
In the petroleum‑machinery sector, such bi‑metal liners typically use a carbon‑steel grade comparable to ASTM A335 P91 for the outer layer. The high‑chromium inner alloy commonly contains 12‑25 % chromium, a range that is standard for wear‑resistant liners. Typical hardness for the inner sleeve falls between HRC 55 and HRC 60, which aligns with the supplier’s claim of high hardness. Standard packaging for these components is a wooden crate with internal bracing, protecting the finished dimensions during transit.
The liners are suited for down‑hole drilling equipment, reciprocating pumps and high‑pressure compressors where abrasive slurry and corrosive fluids are encountered. Importers such as oilfield service companies and equipment manufacturers usually request certification of material composition and dimensional inspection reports. Buyers should confirm the preferred Incoterm, lead time and payment schedule directly with the supplier before placing an order.

Sourcing Double Metal Cylinder Liners from Dezhou Boru Petroleum Machinery Manufacturing Co., Ltd - China Import Guide
Before confirming an order, importers should verify that the supplier can provide a full material test report confirming the carbon‑steel outer shell and high‑chromium inner alloy specifications. It is advisable to ask for a recent factory audit report or third‑party certification that validates the production process described. Confirm the exact dimensions, tolerance limits and packaging method to ensure the liners will fit the intended equipment without modification.
Logistics arrangements should be clarified early; ask the supplier which Incoterms they can offer, such as FOB Tianjin or CIF Shanghai, and obtain an estimated lead time for the bi‑metal liners after final inspection. Payment terms are typically negotiated on a TT or L/C basis, but the exact schedule must be agreed in writing before shipment. Shipping weight and crate dimensions should be confirmed to avoid unexpected freight costs.
Quality assurance can be reinforced by arranging a pre‑shipment inspection performed by an independent inspection agency, focusing on hardness, dimensional accuracy and surface finish. Request the supplier’s certificate of conformity and any relevant ASTM or ISO test results that correspond to the typical standards mentioned. Maintaining a clear record of these documents will simplify customs clearance and downstream quality control.
