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:How can galvanized steel tubes be painted on the surface?
The market is commonly used in alkyd iron red primer, iron red epoxy primer are not suitable for galvanized parts, otherwise it is easy to fall off. It is important to point out that the saponification of the galvanized sheet with alcohol, acid and paint will result in the failure of the coating and the damage of the original zinc coating.
Q:How much is the wall thickness standard of building 48?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Butt fastener: used for connecting two steel pipe joints.The base and the pad: is set up in the bottom of the pedestal pole, pay attention to the distinction between base and the base plate, usually with steel plate and welded steel pipe, base usually put on a backing plate, and the plate can be wood can also be plate.The foot board (see the diagram below), safety net (no explanation, this is very simple).
Q:How to identify stainless steel pipe and steel pipe?
The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:Can galvanized steel tubes simmer?
Galvanized pipe bending is one of the elbow, the surface of the pipe is coated with a layer of zinc material to improve the corrosion resistance of the elbow. Galvanized pipe bending hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, zinc plating cost is low, the surface is not very smooth. Galvanized pipe bending cold tube, hot tube, the former has been banned, and the latter is also advocated by the state for the time being.
Q:What is the difference between seamless steel pipe and welded pipe?
The thicker the diameter, the more commonly the spiral weld. The seamless steel pipe is generally molten state molten steel through the annular slot backlog, and then stretched and other treatment process, so that there is no weld. On the performance, especially the pressure capacity of the steel pipe than ordinary steel has greatly improved, so often used for high voltage equipment.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
Q:What's the use of steel pipe?
No other type of steel can replace the steel tube entirely, but the steel tube can take the place of some sections and bars. Steel pipe is very important to the development of national economy and the improvement of human life quality, much better than other steel products. From the people's daily utensils, furniture, water supply and drainage, gas supply, ventilation and heating facilities to all kinds of agricultural machinery equipment manufacturing, underground resources development, national defense and space use guns, bullets, missiles, rockets and so cannot do without steel.
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
Galvanized steel pipe is commonly known as "cold plated tube", using electroplating process, only galvanized steel pipe in the outer wall, the wall of the pipe is not galvanizedHot dip galvanized steel pipe adopts hot-dip galvanizing process, and the inner and outer walls of the steel pipe have zinc coating.
Q:45 and 316 which steel tubes are of high hardness?
This depends on the heat treatment state, if 45 steel, 314 stainless steel without heat treatment, 316 stainless steel hardness, if the heat treatment, that is 45 steel hardness.
