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 is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Seamless steel pipe material is steel, but also seamless, high strength, used in high pressure, harsh environment occasions. The galvanized pipe is only made on the steel tube, which is similar to the so-called antirust paint
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized steel pipe with hot-dip galvanizing or galvanized coating on it. Galvanizing can increase the corrosion resistance and prolong the service life of the steel pipe. The use of galvanized pipe is very wide, except for water, gas, oil and other general low pressure fluid pipeline, is used in petroleum industry especially offshore oil well pipe and oil pipe, chemical coking equipment oil heater, cooler, oil pipe exchanger for coal distillation, and support piles, Zhanqiao mine tunnel the tubes.
Q:How can galvanized steel tubes be painted on the surface?
Suitable for galvanized base material (antirust primer), epoxy zinc yellow primer (double component), epoxy ester zinc yellow primer.Pretreatment of galvanized sheet when brushing:1, conditional, you can zinc plating phosphating treatment, or first spray a layer of phosphating primer.2, or smooth zinc plating surface sweeping treatment.3, the galvanized workpiece, galvanized pipe surface with solvent (that is, epoxy zinc yellow primer, thinner) wipe, in order to remove the workpiece crude oil protective layer, and increase cleanliness.4, two-component epoxy zinc yellow primer: in strict accordance with the proportion of paint and curing agent paint, and aging 30 minutes later, modulation suitable construction viscosity, you can spray.One component epoxy ester primer: zinc yellow construction viscosity suitable to construction of modulation, the correct construction method.
Q:How to identify stainless steel pipe and steel pipe?
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).Bundled steel pipe2. welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.
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:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
First, the surface of the steel pipe is treated by embroidery, which is more durable, not faster than the rapid oxidation, and will not form white rust on the steel tube;Two. The steel pipe is fully protected. After heating, each part of the steel pipe is plated with zinc, and the concave convex part is protected;
Q:How do you solder purple copper plate and steel tube?
When the copper pipe and the size is not too large, such as 10 mm below the pipe welding, brazing is suggested, with brass solder, such as Wei Odin 201 solder, with supporting solder paste, with a neutral flame welding, the copper plate is heated to about 800 degrees, and then use the solder with 201 Wei Odin 201-F in solder welding, welding wire with melt molding.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
The straight seam welding is relative to the spiral welding and the T-shaped welding, and so on.
Q:DN150 welded steel tubes one meter multiple
Calculated theoretical weight (Kg) per inch of welded steel pipe = (outside diameter wall thickness) * wall thickness * 0.02466DN150 welded pipe, "150" means nominal diameter of 150mm. Its outer diameter is 165mm.
