By default, we use sturdy export wooden cases for packaging, which already provide adequate protection for the ends of seamless pipes. Therefore, we typically do not apply plastic pipe caps. However, if you have this requirement, please let us know in advance, and we will apply the caps free of charge.

Unless you specifically request otherwise, we will perform non-destructive testing (NDT) in accordance with applicable standards. Some standards specify only one type of NDT method, so we may flexibly decide whether to perform eddy current testing based on the specific dimensions of the pipe. However, if you specifically require eddy current testing, we will carry it out according to your request.

Pickling is a common surface treatment process that involves immersing seamless tubes in an acidic solution to dissolve scale, rust, and other impurities on the tube surface through the chemical action of the acid. Pickling not only gives the tube surface a uniform, matte finish but is also an essential preparatory step prior to cold rolling or cold drawing.

Polishing is a process in which the surface of seamless pipes is ground to achieve a glossy appearance. The surface of polished seamless pipes is smoother and more aesthetically pleasing. If you have high requirements for the inner surface, we can also polish the inner walls. The processed pipes are called sanitary pipes and are commonly used in the food and medical industries.
