Our manager denounced that we’ve got another three years for the API-5CT steel pipe guarantee. No matter our customers need seamless steel pipe or welded one, now we have confidence to provide them with high quality steel pipelines.
The American Petroleum Institute has grants to our company with the right to use the Official API certificates. And the types of the steel pipe would be the API-5CT. For the specific certificate number, it is the 5CT-0356. This means our company's skill and experience enable us to preside over the business of steel pipe production in an efficient way. Thus, we have confidence to serve our steel pipe's buyers well. For more details about the licence, you can have a view for the following picture.
