Going over my work before I have to submit. I have one doubt before I do it.

The sentence is---
If you hurry you will be able to keep your appointment.
I say two independent clauses with no comma, but If you hurry sounds like an order ofexpression to set outside. Am I right to say no comma.

Yes you are correct.
No!

"If you hurry" is a dependent clause, not an independent one.

There needs to be a comma after it, before the main (independent) clause.
