Carbon crystal composite cylinder liner

Carbon crystal composite cylinder liner series products have been widely used in CNPC Oilfield, Southwest Oil and Gas Field, and Changqing Oilfield in the past ten years.

Supply Size:3”, 3-1/2”, 4”, 5”, 6”

Technical features:

Customized special grade steel with balanced mechanical properties

Ultra-fine treatment process

Features:

High mechanical strength

Tensile strength, yield strength and toughness are greatly improved compared to bimetal cylinder liners

High hardness

The surface hardness is 61-63HRC, while taking into account toughness to avoid premature micro-cracks due to abrasive wear.

High pressure

High mechanical strength and one-piece structure without inner jacket will not cause the cylinder to fall off or explode.

High security

Integrated manufacturing with high-strength seamless steel pipe, no risk of cracking and pressure release

Highly economical

Since it is made of a single material, the cylinder liner can be recycled, processed and reused after wear and failure.

Little environmental pollution

Product materials do not contain heavy metal chromium, and there is no heavy metal pollution during production and use.
