Eddy’s current non-destructive testing method for the weld seam of spiral welded pipe
As an efficient special means of transportation, pipeline transportation has played an increasingly important role in the fields of oil and natural gas transportation. At present, domestic large-diameter transportation pipelines are mainly constructed with spiral-welded steel pipes. To ensure the...Read more -
What is the difference between the surface processing of spiral steel pipe and stainless steel pipe
The original surface of the stainless steel tube: NO.1 The surface that is subjected to heat treatment and pickling treatment after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc., the thickness is thicker from 2.0MM-8.0MM. Dull surface: ...Read more -
The problem of uneven thickness of the anti-corrosion coating of the spiral steel pipe and the treatment method
Spiral steel pipes are mainly used as fluid pipes and piling pipes. After the steel pipes are made, if they are used for running water, they will generally be treated with anti-corrosion on the inner or outer surface. The general anti-corrosion includes 3pe anti-corrosion, epoxy coal tar anti-cor...Read more -
Several tips to prevent pipeline corrosion
Pipe corrosion occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it is prone to rust and can form cracks and holes, which is a big problem. Therefore, pipeline corrosion protection is critical, especially because once corrosion beg...Read more -
Introduction of the production process of steam direct buried pipeline
Due to its good thermal insulation performance, the steam direct buried pipeline is used more and more, so the steam direct buried pipeline is widely used in urban construction projects, but many people do not know this new type of thermal insulation pipeline product. Let me introduce to you the ...Read more -
The characteristics of fire protection plastic-coated steel pipe, the difference between galvanized steel pipe and plastic-coated steel pipe
First, the characteristics of fire protection plastic-coated steel pipe: 1. Hygienic, non-toxic, no fouling, no growth of microorganisms, and ensure fluid quality. 2. Strong flame retardant ability. Under the combustion test, the coating has no spontaneous combustion and does not fall off. 3. The...Read more
