1Structure of Seamless Pipe GB3087: 

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.

 

Standard: GB3087: Seamless Steel Tubes for Low and Medium Pressure Boiler
● Application: For manufacturing heating-pipelines, containers, steaming pipelines of low or medium pressure
boilers (p≤450℃, work pressure ≤5.88 Mpa)

 

 

2‍‍Main Features of the Seamless Pipe GB3087:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:Is the same specification seamless steel pipe more expensive than welded pipe?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
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:Where is a steel pipe casing usually used?
A straight tube of carbon steel sheathed on pipes and tubes and threading tubes to protect the joints from damage by electric welding. The purpose is to protect the wires and cables.
Q:What does cathodic protection of steel tubes mean?
The corrosion of metals causes great economic losses directly or indirectly. Foreign statistics show that every year due to corrosion and scrap metal materials, equivalent to 20~40% of metal production, the world every year due to corrosion and loss of metal reached more than 1 tons.
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
PE pipe, polyethylene pipe, the past is also commonly used in low temperature water, but because of its short life now use less prone to aging, more PE material for the production of plastic bags;
Q:What connections are there for concrete filled steel tubular column foundations?
In the connection work, strengthening ring joint stiffness, high bearing capacity and no parts through the tube, it is especially suitable for the small diameter steel tube concrete column structure, complex engineering projects, especially those in the pump sending pouring construction method, which is more important, it has a basic guarantee strictly for the quality of concrete construction. When concrete columns with larger diameter, ring type joint construction steel is large strengthened, so as to make the project construction become more complex, and the connection between the longitudinal rebars becomes cumbersome.
Q:Is hot dipped plastic pipe steel?
The characteristics of hot dipped plastic pipe are:1., hot dipped plastic pipe superior anti-static performance: through the formula to add antistatic agent, so that its internal and external surface resistance value reached and exceeded the national industry standards.2., such as the use of plastic raw materials, add flame retardants. The flame retardant performance index conforms to the national standard, and the steel plastic composite structure has better flame retardance than the pure plastic pipe material, and is suitable for underground inflammable, explosive and other places.3. hot dip coating steel strong adhesion: steel surface after special treatment, curing, coating adhesion is greater than or equal to 30N/10mm.4., dense internal and external resin layer: coating thickness of more than 0.5 mm, no pinholes, with excellent corrosion resistance.The mechanical properties of plastic steel pipe superior 5. hot dip: can withstand the harsh conditions of use: coating steel has good toughness, high mechanical strength, impact bending and other foreign influence, has a strong bearing capacity, has better performance than other mine plastic pipes.6. hot dip steel corrosion and fouling, the fluid resistance is small: corrosion and fouling, especially suitable for the underground conveying high sulfur water and transport of calcium and magnesium plasma water, save the maintenance cost, service life is much higher than that of the other pipe, high economic benefit.7. self lubrication: smooth wall, no fouling, small transmission resistance, under the same conditions, can improve the transport capacity of 30%.8. convenient and reliable connectionThe utility model completely overcomes the defects of the difficult connection of the pure plastic mining materials, and can be connected with the underground steel pipe and the valve by using flanges, fast couplings, etc., and has strong interchangeability.
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless steel pipe DN15 specification phi 18*3 refers to 3 outer diameter of 18mm B type DN15 seamless steel tube.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
According to the metal processing performance, pipe size, quality requirements, as well as investment and benefits to choose different processing methods and corresponding auxiliary processes. The basic process of cold rolling of cold drawn pipe are: (1) tube feeding, the pipe material for hot-rolled finished or semi-finished tube, pipe extrusion pipe and welded pipe; (2) pipe material preparation, including inspection, bundling, pickling, cleaning, washing, drying, neutralization, grease and so on; (3) cold processing (cold or cold); (4) finished finishing finished including heat treatment, straightening, sampling, end cutting, inspection (manual inspection and various testing), pressure test, oiling, packaging and warehousing etc.. Different products are refined and the content varies.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Steel pipe and seamless linking points, you said should refers to ordinary steel pipe joints, if only consider the butt welding problem, two kinds of steel can be welded. But the mechanical properties of the seamless steel pipe and tube with different, generally the main difference is the two kinds of steel can withstand the pressure of the former than the latter to be good.So if your project is seamed steel pipe can be, then the two pipe welding, welding and butt welding interface is completely no problem.
