WeldabilityDifferent product uses have different requirements for welding performance. A class of tableware generally does not require welding performance, even including some pot companies. However, most products require good welding performance of raw materials, such as Class II tableware, thermos

Seamless steel pipe occupies an important position in the national economy. Maybe friends don’t understand it very well, but it has been widely used in petroleum and chemical industries, bringing great convenience to people’s lives. . Seamless steel pipes are also divided into many categories, a

The purchase of seamless steel pipes requires the purchase of good quality, so that the money spent is worth the money. If you purchase poor quality steel pipes at a high price, not only the cost will increase, but the construction quality will be affected, so you must learn to judge the quality of

The use of seamless steel pipes lies in the transportation of pipelines, and some solid and gas transportation will also be used in seamless steel pipes. Under our feet, there are seamless steel pipes of different sizes. It is this connection of sections that makes our lives so convenient, and that

Seamless steel pipes are very common. Commonly used seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, and are mainly used as pipelines or structural parts for conveying fluids. According to different uses, it can be divided i

Galvanized steel pipes can actually rust, but the galvanized layer is first oxidized to protect the steel pipe from rusting, and its service life is longer. The chromium-plated chromium layer will not react with oxygen, carbon dioxide, and water in the air under natural conditions, and will not be c

1. After the steel pipe is galvanized, the surface is covered with a layer of zinc coating, which isolates the steel pipe from the atmosphere, avoids direct contact and corrosion of the steel pipe by the atmosphere, and is protected. The zinc coating on the surface of the steel pipe, due to the rela

As indoor gas pipelines have to bear a certain pressure, gas leakage will cause explosions and fires, causing casualties and economic losses. Therefore, the basic requirements for indoor gas pipelines are: sufficient mechanical strength (tensile strength, elongation), good connectivity, and airtight

After the steel pipe is galvanized, the surface is covered with a layer of zinc coating, which separates the steel pipe from the atmosphere, avoids direct contact and corrosion of the steel pipe by the atmosphere, and is protected. The zinc coating on the surface of the steel pipe, due to the relati

1. No. On the one hand, because the galvanized square tube has a galvanized layer, it is superior to the ordinary welded square tube. It also has better strength, toughness, and other process properties. Its surface has gloss, making it more widely used. Applications include glass Curtain walls, pow
