delete duplicate line features?

[AYGÜNALBAYRAK]

I want to clean my data which is occured from line features. I try to get one line feature among other intersecting line features.

Not sure if this is what you are after, but I'll throw it out there:

If the issue is that the lines are roughly parallell and close but not coincident, one solution to make them coincident so one could then follow up and dissolve them down to a single line is Integrate:

Integrate—Data Management toolbox | ArcGIS Desktop 

Caution - this tool alters the original data (i.e. does not make a new output like most geoprocessing tools do), so be sure to save off copies of your original data as backups.  Also, one typically has to do several trial runs to find the best XY Tolerance setting for use in the tool to provide the maximum effect with the least distortion.

This tool is all about that I want to create. However, I do not use ArcGIS Pro  Thanks for your help.

You do not need ArcGIS Pro to use the Integrate tool. Integrate—Help | ArcGIS for Desktop 

Setting up database topology rules might also help with identifying errors and cleaning up the data.
