Carbon steel tubes are made of steel castings or solid round steel through holes to make capillaries, and then made by hot rolling, cold rolling or cold drawing. Carbon steel tubes have an important position in China’s seamless steel tube industry. The key materials are mainly q235, 20#, 35#, 45#, and 16mn. The most important product implementation standards include…
Read MoreFire-fighting pipeline refers to the pipeline material used for fire-fighting, connecting fire-fighting equipment and equipment, and transporting fire-fighting water, gas or other media. Due to special requirements, the thickness and material of fire-fighting pipes have special requirements, and red paint is sprayed to transport fire-fighting water. Since the fire pipeline is often in a static state, the requirements for…
Read MoreCarbon steel black pipe is uncoated steel, also known as black steel. The dark color comes from iron oxide that forms on its surface during the manufacturing process. When a steel pipe is forged, a black scale forms on its surface, giving it the finish seen on this type of pipe. Carbon steel galvanized pipe is steel covered with…
Read MoreThe outer coating of welded pipe FBE fused epoxy powder (FUSION BOND EPOXY) anti-corrosion steel pipe is a new type of anti-corrosion coating developed in the past 30 years. The coating has the characteristics of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance, and has been widely used abroad. Powder coating is…

Compared with others, the quality of such seamless steel pipes is There are some practical differences. 2. Use of seamless steel pipe for fluid transportation: This type of seamless steel pipe is widely…
Read MoreThe anti-corrosion coating of seamless steel pipe refers to the use of paint to uniformly and densely coat the surface of the rust-removed steel pipe to isolate it from various corrosive media. It is one of the most basic methods for anti-corrosion of seamless pipes. There are many kinds of anti-corrosion coatings, and their properties and uses are different….
Read MoreClassification by steel pipe material: Steel pipes can be divided into: carbon steel pipes, alloy steel pipes, stainless steel pipes, etc. Carbon pipes can be divided into ordinary carbon steel pipes and high-quality carbon structural pipes. Alloy tubes can be divided into: low alloy tubes, composite tubes, financial tubes, high-strength tubes, precision alloys (such as Kovar) tubes, and high-temperature…
Read MoreThere are two types of galvanizing methods for seamless tubes: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing includes wet method, dry method, lead-zinc method, redox method, etc. The main difference between different hot-dip galvanizing methods is what method is used to activate the surface of the pipe body after acid dip cleaning of the steel pipe to improve the quality…
