How to Coat the Inside of Casing, Tubing

06/17/2016 7:47 AM

Hi,

I'm wondering if coating the inside of Casing or Tubing is possible or not.

mainly, the coating material will be Monel or Inconel and usually these material is used for its resistivity to corrosion.

P.S.: the Casing and Tubing are used for oil and gas industry.

Thanks in advance,

Inconel coating

Obviously it is possible. It is just as obvious that you cannot perform this coating.

didn't get your point.. if it's possible why I can't perform this coating ?

First, somebody else with the technology and experience to do Inconel coatings may be able to coat these surfaces. You obviously cannot perform this service yourself.

Second, while while most clean piping used in the oil and gas industry can safely take a metallic coating, I'm certain some won't. You do not indicate at all what types of pipes you have. Then there's the question of where you want these pipes coated? Where as in both where on the pipe you want this coating and where will this coating process be performed, on a floating drilling rig or at the pipe manufacturer's factory?

I recommend that you get these and many other facts together before contacting one of the metal coating fabricators on the Google search page. Ask them.

obviously you don't know what I'm talking about as obviously you don't have experience in Oil and gas industry.

let me tell you some points to help you understanding my question and if you feel it's outside your field just don't have to answer.

first, my question was if it's possible to coat the inside surface of casings and tubing. for sure I won't be able to coat it by myself. did you really think I was thinking to perform the coating at FLOATING RIG???

Inconel or Monel coatings are done by "Thermal Arc Spray" technology which has to be done in specialized workshops. However, this technology is for outside surface only and I was investigating how it can be done for the inside surface of the casings or tubing as the arc spray gun can't go inside them (bigger diameters).

if you don't have an answer for this question, don't answer and let someone who knows to answer.

You are correct, I don't know what you are talking about. It's not because I have no experience with Inconel coatings. (Our accelerator cryogenic ceramics are often coated with Inconel to handle the image currents.) I have no idea what you are talking about because you are not clear in what you are talking about. You need to be much more clear about your pipe coating wishes when you contact a company that does metallic coatings. They may recommend another sputtered metal (we also use titanium) or even propose a better solid metal for your pipe.

There is a UK company could do what you want within reason. Unless you impart some information, I’m not going to let you waste their time.

I posted a question and I was looking for a useful answer. at the end it's an engineering community (or at least it's what I thought when I signed up for this website). I don't know who put you a "time guardian" for others.

if they don't want to answer simply they can ignore it, you could do the same by the way..

Did you notice the registered description for CR4.

So far you've not contributed very much to your own discussion.

You posted a question and you dislike the answer you were given. Then I guess you will just have to pay somebody for their services. You shouldn't be surprised when you don't like their fee and their answer.

Most things can be done and the members here will know a way to do it but it helps if we know what needs to be done in the first place.

Your abrasive manner won’t endear you to people who give their years of experience for free.

I'm done arguing with you, I already got what I need from another place...

you can keep your experience for yourself which knowing coating the inside of casings or tubing is not a big deal.
