Pickling Surface Round Square Pipe is the process of removing impurities, such as rust, from the surface of a metal. This is done by submerging the metal in a pickling solution, which can be either an acid or a base. The impurities are then removed from the surface of the metal via a chemical reaction.

Pickling is often used on iron and steel products, as it is an effective way to remove rust and other impurities. The pickling process can also be used on other metals, such as aluminum and copper. Pickling Surface Round Square Pipe is a simple and straightforward process that can be completed at home with the right supplies.

1. Seamless Round Square Pipe is a new kind of pipe that is made with a completely new process.

2. This pipe is made with a unique process that makes it much stronger and more durable than traditional pipes.

3. Seamless Round Square Pipe is perfect for any application where strength and durability are important.

Seamless Round Square Pipe
Welded Round Square Pipe is a type of pipe that is commonly used in various industries. The pipe is made from a variety of materials, but the most common material is steel. The pipe is welded together at the seams to create a strong and durable product. There are many benefits to using Welded Round Square Pipe, including the fact that it is very strong and can withstand high pressures. Additionally, the pipe is very easy to install and can be used in a variety of applications.

Stainless Steel Pipe classification

Stainless steel pipe according to the material is divided into ordinary carbon steel pipe, high quality carbon structure steel pipe, alloy structure pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe and bimetallic composite pipe to save precious metals and meet special requirements, coating and coated pipe. There are many kinds of stainless steel tubes, different uses, different technical requirements, production methods are also different.

The current production of steel pipe diameter range 0.1-4500mm, wall thickness range 0.01~ 250mm.
Hardness testing of Stainless Steel Pipe

W-B75 Wechls hardness tester can be used for annealed stainless steel pipe whose inner diameter is above 6.0mm and wall thickness is below 13mm. The test is very fast and simple, which is suitable for rapid and nondestructive qualified inspection of stainless steel pipe. The HRB and HRC hardness of stainless steel tubes with inner diameter greater than 30mm and wall thickness greater than 1.2mm are tested by Rockwell hardness tester. For stainless steel tubes with inner diameter greater than 30mm and wall thickness less than 1.2mm, use surface Rockwell hardness tester to test HRT or HRN hardness. Stainless steel pipes with inner diameter less than 0mm and greater than 4.8mm are tested with Rockwell hardness tester for HR15T hardness. When the inner diameter of stainless steel pipe is greater than 26mm, Rockwell or surface Rockwell hardness tester can also be used to test the hardness of the inner wall of the pipe.
Stainless Steel Pipe section shape

Stainless steel pipe according to the cross section shape can be divided into round pipe and irregular pipe. Special-shaped tube has rectangular tube, diamond tube, elliptic tube, hexagonal tube, eight direction tube and various sections of asymmetric tube. Special-shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the special-shaped tube generally has a larger moment of inertia and section modulus, a larger bending resistance, torsion resistance, can greatly reduce the weight of the structure, save steel.

Stainless steel pipe according to the longitudinal section shape can be divided into equal section pipe and variable section pipe. There are conical pipe, stepped pipe and periodic pipe with variable section.

The advantages of stainless steel pipe application practice

1.life

Stainless steel tubing has the longest service life. From the analysis of the use of stainless steel abroad, the service life of stainless steel water pipe can reach 100 years, at least 70 years, as long as the life of the building.

2. Corrosion resistance

One of the most prominent advantages of stainless steel pipes is its excellent corrosion resistance, which is the best among all kinds of pipes. Because stainless steel can passivate with oxidant, forming a layer of tough and dense chromium rich oxide protective film Dr2O3 on the surface, effectively prevent further oxidation reaction.

3. Heat and insulation

The thermal conductivity of stainless steel pipe is 1/25 of that of copper pipe and 1/4 of that of ordinary steel pipe. It is especially suitable for hot water transportation. The most commonly used stainless steel in the water industry are 202 and 304 stainless steel, which can meet the vast majority of water treatment and transportation conditions.

4: Strength

The tensile strength of 304 stainless steel pipe is 2 times that of steel pipe and 8~10 times that of plastic pipe. The strength of the material determines whether the water pipe is strong and crash-resistant, safe and reliable.
