Q:Are the welded and galvanized tubes the same weight?
There should be no difference in the weight of the same specifications for the welded pipe and galvanized pipe. The slight difference is that the galvanized pipe should be pickled before galvanizing and must digest some iron and then galvanized. The difference depends on the difference in the process. So the theoretical calculations are the same.
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing is zinc plating, the general surface is relatively smooth, no zinc flowers, there are two kinds of resistance to fingerprints and non - Fingerprint
Q:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
Galvanized steel pipe is a kind of antirust steel pipe, often used in relatively high water supply pipeline or hot water pipeline, the price is higher, can use for at least 30 years;PPR pipe is a kind of polypropylene plastic, which is commonly used in environmental protection plastic pipes, but only suitable for low temperature occasions. It is mainly used for water supply;
Q:Are steel tubes and round steel in weight or length when purchased?
It's priced by weight. The cutting process should size to determine the length (otherwise - please specify the weight of the material), the material ration to calculate weight for cost accounting as.
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
Q:What does cathodic protection of steel tubes mean?
Applied current: a macro cell consisting of a protected metal piece and an insoluble auxiliary component. The negative electrode of the battery is connected to the metal to be protected. The power supplies the electrons so that the metal is not corroded by missing points.
Q:Does the seamless steel pipe need rust removal?
The use of solvent, emulsion cleaning steel surface, in order to achieve the removal of oil, grease, dust, lubricants and other similar organic compounds, but it can not remove rust, scale, welding of steel surface, so the production in anti-corrosion only as an auxiliary means.
Q:Can stainless steel pipes spray black paint?
Stainless steel pipes can spray black paint.The stainless steel surface with a layer of smooth surface, so the painting before the need to use corner grinder or iron brush to paint out into hair and then paint. Otherwise, spray paint can not be adhered to the surface of the stainless steel pipe.
Q:What does "HBB" glass steel pipe mean?
HBB glass fiber reinforced plastic cable protection tube is suitable for power, communication and communication cables laying protection pipes in all kinds of occasions. Especially in the traffic crossing through cable and cable bridge across the river, the use of the special environment, more fully reflects its simple construction, high strength performance, widely used in the construction of infrastructure, transportation, electricity, communications and other fields of Civil Aviation Airport
Q:How seamless steel tube is formed?
Seamless steel tubes are formed by cold drawing and hot rolling.
