Wet process phosphoric acid is quite corrosive due to dissolved F; it is suitable for fertilizers, not for contacting steel surfaces. Usual concentration for handling is 54% P2O5, that is 75% H3PO4 (w/w). Having no experience on thermal process phosphoric acid (from P burning), I guess this can be used for cleaning /rust removal of metal surfaces.
Seamless Carbon Steel Pipe. Seamless carbon steel pipe has, as its name implies, no longitudinal weld seam. It is, in essence, one solid homogeneous piece of steel. A solid billet is simply heated and then stretched over a series of mandrels until the pipe has

Seamless and welded are mainly two types stainless steel tube & stainless steel pipe, there is a debate whether seamless is better than welded for a long time. Although with improved metallurgy and welding processes in welded tubes, the arguments typically focus on
Typically, a light amount of oil is applied to steel pipes at the end of the production line. This helps protect the pipe. While it is not actually a part of the finished product, sulfuric acid is used in one manufacturing step to clean the pipe. The Manufacturing Process Steel pipes are made by two different processes.
Boiler steel pipes includes medium pressure boiler pipe and high pressure boiler pipe, it is often manufactured in seamless procedures, welded steel pipe is not applicable. It has been widely used at heat exchanger pipe and tubing services, tube exchanger bundle, high pressure boiler, economizer, super heater, petrochemical industry pipes, etc.
Stainless steel welded and seamless pipes are used for variety of reason such as to resist corrosion, preform at high temperature, for clean look and low maintenance cost. The most important aspect for stainless steel pipe is its inherent material characteristics that allows much thinner walls to be created such as sch 5, sch 10 without compromising the structural integrity of the pipe.
Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications.

Stainless Steel 310H Rectangular Pipes makes ferrous sulphate when reacted with sulphuric acid, where this reaction with sulphuric acid is used to clean metal. Stainless Steel 310H Hexagonal Pipes reacts with air and water to make rust, whereas other metals like aluminium do not rust away.
A clean stainless steel surface can be re-damaged through mechanical means, extreme heat, or chemical damage. When this happens, iron is exposed, and the material is once again subject to rusting. Passivation may need to be performed on a regular basis to prevent rust.
In the case of pickling, the seamless steel pipe has a stripping effect on the iron oxide scale, and also diffuses into the interior of the steel billet matrix and accumulates at the impurities or pores, resulting in an increase in internal stress, a decrease in the plasticity of the steel, and an increase in the brittleness of the steel. The effect is called hydrogen embrittlement.
