Product Description:

1、Structure of Stainless Steel Seamles Pipe 304 ASTM A312 Description:

Stainless seamless 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. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.



2、Main Features of the Stainless Steel Seamles Pipe 304 ASTM A312:


• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

Q:SC15 what does galvanized steel pipe look like?
DN15 galvanized pipe, nominal diameter of 15mm
Q:How to distinguish seamless pipe and welded pipe?
The way to distinguish seamless pipes and welded pipes is to see if there is weld marks on the port.
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:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Galvanized steel pipe wall thickness weight outer diameter 108mm 4mm 6 meters in length is about 10.26*6*1.06=65 kg.Kg/m= (outside diameter mm-, wall thickness mm) * wall thickness mm*0.02466= (108-4) *4*0.02466=10.26 kg / MBecause of galvanizing, the weight is heavier than that of ordinary welded pipe 3%~6%.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Sort by connectionThe connection way of steel pipe can be divided into: light pipe (pipe end without thread) and wire tube (Guan Duan with thread).The tube can be divided into ordinary tube and end tube.Thickening of the tube can also be divided into: extra thick (with external thread), internal thickening (with internal thread) and inside and outside thickening (with internal and external thread) and other vehicle wire tube.The wire tube can also be divided into ordinary cylinder or taper thread and special thread.In addition, according to user needs, wire tubes are generally equipped with pipe delivery.Plating characteristicsAccording to the characteristics of surface coated steel pipe can be divided into: Clarinet (not coated) and coating tube.The coating tubes include galvanized pipes, aluminium plated tubes, chrome plated pipes, aluminized tubes and other alloy layers.The coating tube has an outer coating tube, an inner coating tube and an inner and outer coating pipe. The commonly used coatings are plastics, epoxy resins, coal tar, epoxy resins, and various glass based anticorrosive coatings. Galvanized pipe is divided into KBG pipe, JDG pipe, threaded pipe, etc.
Q:What's the difference between steel pipe and pipe fittings?
Steel: steel pipe is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is 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: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:RC is it welded steel pipe or galvanized steel pipe?
The basic knowledge of wire tubes - wire tubes, SC is welded steel pipe, RC is galvanized steel pipeThe basic wire pipe is the minimum requirement in the steel pipe. For so long, I wonder if you will adopt it
Q:What is the process of spiral steel tube production?
X ray flaw detection: 100% X ray industrial television inspection of internal and external weld seams, and image processing system is adopted to ensure the sensitivity of flaw detection.8. press test: the steel pipe is tested by root test on the water pressure test machine to ensure the test pressure of the steel pipe to meet the standard requirement.9. chamfering flat head: the qualified steel pipe is processed at the end of the pipe to achieve the required size of the end of the pipe10. final inspection: ultrasonic and X ray inspection, and magnetic particle inspection at the end of pipe to check for welding problems and pipe end defects.11., marking: qualified steel pipe for oil, in order to prevent corrosion, and according to user requirements for marking.
Q:How to establish a concrete-filled steel tubular column model in ANSYS?
A two unit model or a composite unit model can be adoptedTwo units are constructed of steel tubes and concreteA composite unit may be either a fiber element or a section conversion attribute
