description

This tube assembly is made of high-strength seamless steel pipe with integrated fittings and sealing shoulders. It is developed for fuel supply circuit of drilling power unit, resisting oil pressure pulsation and continuous vibration to guarantee accurate fuel delivery. Thinned wall, fatigue weld crack, damaged sealing shoulder and stripped thread will trigger fuel leakage and pressure fluctuation, resulting in engine speed instability, and fuel leakage brings fire hazard.

Part No.:352-1508
Type: Seamless steel fuel tube assembly
Material: High-strength seamless carbon steel
Process: Precision bending, fitting welding, non-destructive testing
Compatible Fluid: Diesel fuel
Working Condition: High pressure and pulsating vibration for fuel circuit of petroleum power unit
Matching System: Engine high-pressure fuel supply circuit

Application Scenarios

Fits Caterpillar CX31-P600, CX31-C13I petroleum power unit, for overhaul of engine high-pressure fuel supply line.

FAQ 

Q：Can the tube with light surface rust be reused after polishing?
A：Wall thickness measurement is required. Replace it if thickness is below limit, or it may burst under pressure pulsation.

Q：Can slow fuel leakage at fitting be fixed only by replacing O-ring if tube is intact?
A：Check sealing shoulder for scratch or deformation first. Seal replacement cannot stop leakage if sealing face is damaged.

Q：What hazard will it bring if the tube is squeezed forcibly for installation?
A：Squeezing stress plus pressure pulsation causes fatigue crack at weld and fuel spray leakage later.

Q：Can this fuel steel tube be substituted by high-pressure fuel hose?
A：Direct replacement is not recommended. The hose has poorer fatigue resistance under fuel pressure pulsation.
