Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
To look at the use of concrete after welding, if the stress is relatively large and thin galvanized pipe wall is recommended to not use welding, if the requirement is not high Po mouth welding should be welding depends on galvanized pipe material selection electrode generally no sealing material are 20
Q:What's the material of Q325 steel pipe?
In terms of deoxidation methods, F, B, Z can be expressed as boiling steel, flat killed steel, killed steel and boiling steel. They are deoxidized steel, which is of poor plasticity and toughness. Welded joints made of this material are susceptible to cracks when subjected to dynamic loads. Should not work at low temperatures, sometimes hardening. In contrast, calming steel is excellent and uniform, with good plasticity and toughness.
Q:What's the difference between a rectangular tube and a rectangular steel tube?
Rectangular tube is a kind of hollow long strip steel, also known as flat tube, flat square tube or square flat tube (Gu Mingsiyi). A large amount of pipe used to transport fluids, such as petroleum,Natural gas, water, gas, steam, etc., in addition to bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
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?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:How to distinguish between steel pipe and spiral pipe material?
Steel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.
Q:What are the uses of welded steel pipes?
Low pressure fluid conveying galvanized steel tube (GB/T3091-1993) is also called galvanized pipe, commonly known as white tube. It is used for hot water, gas, air, oil, heating, steam, warm water and other generally low pressure fluid or other hot dip galvanizing (furnace welding or welding) steel pipe. The wall thickness of the steel pipe is divided into ordinary galvanized steel pipe and thick galvanized steel pipe. The end of the pipe is divided into non - threaded galvanized steel pipe and threaded galvanized steel pipe. The specification of steel pipe is expressed by nominal caliber (mm). The nominal diameter is the approximate value of the inner diameter. Usually used in inches, such as 11/2.
Q:What is the process of spiral steel tube production?
Shear forming: on the production line will be along the outer edge of the spiral plate winding tube.
Q:How long is the seamless tube?
Seamless steel tube specification: 8-1240 * 1-200mm
Q:What's the difference between round and round tubes?
Round steel is solid and round tubes are hollow
