Product Description:

1、Structure of Galvanized hollow section Pipe API103: 

Galvanized hollow section Pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. We company professional to provide these serious of pipes and what we can give you is not only in good sprice, the most important is we can provide you good quality.

Q:What does "DN25 PN16" mean?
Steel pipe DN25, PN16, first of all, for this annotation: pipe DN class, often used in welded pipe, such as welded pipe DN25. PN16 means pressure, that is, 16 kilograms (1.6MPa).
Q:SC15 what does galvanized steel pipe look like?
Ordinary galvanized steel pipe, the outer diameter is 1.5 inches
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Dimensions of ordinary steel tubes (taken from GB/T 17395-1998)The theory of weight / (kg/m) | wall thickness (2.9 3.0mm: 3.33)
Q:How to identify stainless steel pipe and steel pipe?
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
Q:Can galvanized steel tubes simmer?
Galvanized steel pipe can simmer bending.Is a set of bending bending bending die, no matter what kind of equipment, most are used in pipe, mainly used for oil and gas, infusion, more plays an important role in aircraft and engine.
Q:Does the seamless steel pipe need rust removal?
Chemical and electrolytic methods are generally used for pickling treatment. The pipeline corrosion only uses chemical pickling, which can remove oxide, rust and old coating. Sometimes, it can be treated as sand blasting after rust removing. Two. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, but its anchor grain is shallow, and easy to pollute the environment.
Q:Seamless steel tube 89X4 meters, how heavy?
According to the theory, each meter is 8.3844 kilograms. If you want to be precise, you'll lose your own weight.
Q:How to perform nondestructive inspection of steel tubes
Including fluorescence, coloring two kinds. Because of its simple equipment and convenient operation, it is an effective method to check the surface defect of magnetic particle inspection. It is mainly used for surface defect inspection of non-magnetic materials.
