Effective Methods for Pipe Degreasing and Cleaning

In industrial production, pharmaceutical systems, petrochemical projects, and irrigation systems, pipes often accumulate oil, rust, and organic deposits during processing, transportation, and use. If not promptly removed, this not only reduces pipeline efficiency but can also lead to corrosion, blockage, and product contamination. Therefore, pipeline degreasing (degreasing) is a crucial process for ensuring pipeline cleanliness and extending its service life.

Comparison of the Advantages of SMLS and ERW Steel Pipes

In oil, gas, and fluid transportation projects, SMLS (seamless steel pipe) and ERW (Electric Resistance Welded) are the two most widely used types of steel pipe. Although both are transportation pipes, they differ significantly in raw material selection, production process, microstructure, and performance, which determine their respective advantages and applications. This article will comprehensively compare the advantages of SML and ERW steel pipes in terms of billet quality, geometric dimensions, standard applicability, physical properties, and price.

Basic Calculation Formula for Seamless Pipe Pressure

Seamless steel pipe (SMLS), with its seamless welds, smooth interior, and uniform wall thickness, is widely used in fluid transportation systems, mechanical structures, and energy engineering applications under high pressure, high temperature, and harsh operating conditions. The safety and reliability of seamless pipes are particularly crucial to the stable operation of the entire system in fields such as petrochemicals, power generation, boilers, and pressure vessels. The pressure-bearing capacity of seamless pipes directly determines their application range, making the calculation of pressure on seamless pipes extremely important.

High Frequency vs Straight Seam Welded Pipe

When it comes to welded steel pipes, two terms often cause confusion: high frequency welded pipe (ERW) and straight seam welded pipe. While they sound similar, they are not always the same. In fact, high frequency welded pipes belong to the category of straight seam welded pipes, but they are produced using a very different welding method. Understanding their differences is essential for engineers, contractors, and buyers who want to choose the right product for oil, gas, water, and structural applications.

Do flanges have pressure ratings?

According to ASME B16.5, steel flanges have 7 pressure levels: Class 150-300-400-600-900-1500-2500The pressure rating of a flange is very specific. A Class 300 flange can withstand greater pressure than a Class 150 flange because it requires more material to withstand the higher pressure. However, the pressure resistance of a flange is affected by many factors. The pressure rating of a flange is measured in pounds, and there are several ways to express the pressure rating.

How to Extend the Lifespan of Seamless Steel Pipes

The seamless steel pipes we produce are made of different materials and naturally withstand different elements. Generally speaking, our seamless steel pipes are rust-resistant. However, this doesn't mean we can just leave them alone and rest easy. Failure to properly maintain seamless steel pipes can shorten their service life, causing unnecessary losses for both our seamless steel pipe manufacturer and our customers. Since everyone who purchases seamless steel pipes naturally hopes for a long lifespan, it's crucial to pay attention to their maintenance.

Transport and Packaging Requirements for Steel Pipe Products

Steel pipe, as an essential industrial material, is widely used in industries such as oil and gas, construction, machinery manufacturing, power generation, automotive, and chemicals. Steel pipes are often transported over long distances, involving repeated loading and unloading. Improper packaging can easily lead to deformation, dents, scratches, or corrosion, affecting the product's appearance and performance. Therefore, scientific and appropriate transport packaging is crucial for ensuring steel pipe quality and improving customer satisfaction.
