Five methods for rust removal of carbon steel pipes

 Rust removal of carbon steel tubes (cs tube) is an important step in ensuring the safe operation and service life of pipelines. The following are 5 commonly used rust removal methods for carbon steel tubes:

1. Manual rust removal

Manual rust removal uses hand tools (such as wire brushes, shovels, etc.) to remove the rust layer on the surface of carbon steel pipes. This method is simple to operate and suitable for small-scale rust removal projects. However, for large pipeline systems or pipelines that require high-precision rust removal, the effect of manual rust removal may not be ideal.

2. Electric rust removal

Electric rust removal uses electric tools (such as electric wire brushes, electric shovels, etc.) to remove the rust layer on the surface of carbon steel pipes. This method is more efficient than manual rust removal and can complete the rust removal of a large number of pipes in a short time.

3. Pickling and rust removal

Pickling rust removal is to dissolve the rust layer on the surface of carbon steel pipes through chemical action, and then rinse it with clean water. This method is suitable for rust removal in large-scale pipeline systems, but attention needs to be paid to the selection of pickling liquid and the dosage used to avoid affecting the pipeline material and performance.

4. Solvent rust removal

Solvent rust removal uses solvents (such as dimethyl ether, acetone, etc.) to dissolve the rust layer on the surface of carbon steel pipes, and then rinses them with clean water. This method is suitable for rust removal of small area pipes, but attention must be paid to the safety and environmental protection of the solvent to avoid environmental pollution.

5. High-pressure water jet rust removal

High-pressure water jet rust removal uses a high-pressure water gun to wash away the rust layer on the surface of carbon steel pipes. This method is suitable for rust removal in large pipeline systems and has the advantages of fast speed and high efficiency. However, attention must be paid to the purity of the water and the working pressure to avoid affecting the pipeline material and performance.

It is necessary to choose the appropriate rust removal method according to the specific pipeline conditions and requirements to ensure the safety, stability and long-term operation of the pipeline.

The main reason for the porosity of submerged arc welding seam

 Submerged arc welding technology is the welding process of SSAW steel pipe and LSAW steel pipe. During the welding process, in addition to insufficient penetration, burn-through and poor formation caused by improper welding process parameters, there will also be pores, slag inclusions, cracks, etc. Defects. This article mainly introduces the main reasons and preventive measures for porosity in submerged arc welding seams. (1) In the process of steel rolling or hot stamping and coiling, the oxide scale formed or fallen off, as well as the positioning welding slag shell, the carbon arc gas created flying slag, etc., are trapped in the flux, which will also cause pores in the weld. Preventive measures: ①The oxide skin that falls off during the process of coiling and bending should be cleaned or blown off with compressed air before assembly and welding to prevent it from being caught in the assembly gap or falling into the groove. ②The surrounding of the welding site should be clean t...

Standard for Choosing Oil Casing Pipe Manufacturers

 　　There are many standards for selecting oil casing manufacturers, which can be divided into short-term standards and long-term standards according to the length of time. The short-term standards for selecting oil casing manufacturers mainly include product quality, price level, timely delivery and overall service level. 　　1. Product quality 　　The quality of the purchased oil casing meets the requirements of the purchasing unit is a condition that the purchasing unit must consider when purchasing the oil casing. Poor quality and low price casing products have lower procurement costs, but will lead to an increase in the total cost, but if the quality is too high, it will far exceed the production requirements, which is also a waste. Therefore, the quality requirements of the oil casing in the procurement The production needs of the enterprise must be consistent, and the requirements are too high or too low are not appropriate. 　　2. Lower cost 　　A lower purchase price is an importan...

How to distinguish between ERW steel tube and seamless steel tube?

　　Today, Great Steel Pipe will tell you how to distinguish the ERW steel pipe and seamless steel pipe. 　　 ERW Steel Pipe 　　ERW is a specific type of welding process that is used to produce welded steel pipe, such as ERW steel pipe. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding. The strip then passes through a series of contoured rollers which cold-form the material into a circular (square or rectangular) shape. The edges are forced together under pressure as a butt joint and then welded by heating the material to temperatures above 2000° F. The flash weld that has formed is now removed from the outside diameter of the tube. Once the weld has been tested the tube then passes through a series of sizing rolls to attain its precise finished size, after which the tube is then straightened and cut to length. 　 　Seamless Ste...
