Item specifice:

Standard: AISI,API Technique: Hot Rolled Shape: Round
Surface Treatment: Galvanized Steel Grade: Q195 Certification: ISO,API
Thickness: 5.21 - 16.13 mm Length: 6M Net Weight: 9.5

Product Description:

Integral-joint tubing upsetting at one end, external threading, and external upsetting at the other end, internal threading. API integral-joint tubing is on the market in OD dimensions of 1.315 to a couple of.063 inch.


API integral-joint tubing provides 10-round form together with a joint strength which is less than the body minimum yield, this reduces its use.


The small OD of integral-joint tubing enables its use inside of larger tubing strings or inside of wells as unloading or vent strings.

The couplings will need to meet all the minimum specifications outlined in API Spec. 5CT. API Spec. 5B3 and API RP 5B14 cover threading, gauging, and thread inspection.

Inspection

Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:

  • Dimensions

  • Weights

  • Straightness

  • Lengths

Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.


Inspection Method

  • Size and surface inspection

  • NDT and pressure test and third party certication

  • Hydrostatic

  • Drifting test

  • Physical and chemicail analysis

  • Hardness and pressure test.

  • Electromagnetic

  • Magnetic particle

  • Ultrasonic

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 are the main aspects of precision steel tubes?
Its inside and outside diameter size can be accurate to less than 0.2mm, and it is widely used in the manufacture of precision machinery parts and engineering structure when the bending resistance and torsion strength are the same. It is also used to produce all kinds of conventional weapons, guns, shells, bearings and so on.
Q:Can the KBG25 steel tube hold 4 six types of cables?
1 of the six lines of cross-sectional area of about 25 square millimeters, 4 to 100 flat, KBG25 cross-sectional area of about 490100/490=20.4%, just over the specifications, so short distance and less elbow can be worn. However, due to the construction of pipes are generally not standardized, elbow more, and do not use special elbow (site bending), so KBG25 wearing 4, six kinds of cable are more difficult.
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
You can refer to the ASME B31.10, such as the requirements for the SA106GRB seamless steel tube outer diameter of 168.3 x 7.11, specifications can be marked as NPS6 SCH40 SMLS, the real mark should include pressure steel pipe factory name or trademark, and the material level, specifications, standards, wall number, batch number, pressure test (if any), NDE detection (if any)
Q:What's the difference between straight steel pipe and seamless steel pipe?
Observe whether there is weld seam. Welded pipe without treatment, there are obvious weld, there are bulges, like scars. A better point will shave off the weld, but there is a distinct difference between the eye and the eye. Also a small number of pipe will be processed after cold rolling, surface roughness and accuracy are relatively high, may be counterfeit seamless pipe sales. Careful observation will still show that the pipe wall will have a continuous spiral, metal luster slightly brighter, that is, the original welding seam, metallographic structure and other parts of the difference. To tell the truth, the layman would have to observe that it might be a little difficult.
Q:Fastener type steel pipe scaffold external parts name
Even the wall piece the upright rod is connected with the main structure together, available steel tube, fastener or embedded part. Rigid wall, also can be used as a flexible reinforced wall connecting piece of the tie bar. , 5.The base in the form of plug-in and coat type two, inserted a D1 diameter rod diameter than 2mm, diameter D2 rod diameter than 2mm type jacket.
Q:What is lined pipe?
There are inner pipe jacket, such as day, tube, etc.; there are outside the pipe painted, such as large-diameter water pipes. An internally coated steel pipe for corrosive medium fluids replaces the expensive stainless steel pipe.
Q:Difference between seamless steel pipe and welded pipe
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) pipe etc..
Q:Where is the difference between seamless steel pipe and welded pipe?
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
