Product Description:

API-5CT EUE Tubing Pipe

The API external-upset-end (EUE) tubing pipe is broadly used due to the fact that is a good, serviceable interconnection in the majority of wells.

Without the need of modifying the actual thread shape, the joint dimension will increase because of  upsetting procedure. The EUE joint features a designed joint strength in tension and pressure strength much higher than that of the pipe overall body and, as a result, is considered a 100% joint effective connection.

To enhance  seal efficiency of API EUE tubing in high-pressure system, a grooved coupling, which accepts nonmetallic seal rings, is quite often applied in the coupling (see API Spec. 5CT SR 13).

API EUE joints come in OD sizes of 1.050 to 4.500 inch.

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:What kinds of steel pipe are divided into?
The steel pipe seamless steel pipe and welded steel pipe (tube) two categories. According to the section shape and can be divided into round tube shaped tube, round steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, triangular, octagonal shaped steel tube.Seamless steel pipe: seamless steel pipe is ingot or solid billet made by capillary hole, then hot, cold or cold drawing. Made of seamless steel pipe specifications with outer diameter * wall thickness mm. Number of seamless steel pipe cold and hot points of seamless steel pipe (DIAL) two categories.
Q:Welded and seamless steel pipe how to distinguish?
Different uses:Mainly used for seamless pipe or structural parts of the transmission fluid, mainly used in machinery industry, and seamed steel pipe is mainly used in the construction industry, such as water, gas, compressed air and low pressure fluid. But seamless steel tubes are used in all pressure pipes.
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.
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:Which is cheaper, angle iron or steel pipe?
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.Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:How to make the magnetic steel, can be like a magnet?
Of course, not all materials can be magnetized, austenitic stainless steel will not do.
Q:What is ND steel pipe?
ND steel also has the ability to resist chloride ion corrosion. ND steel pipe, the main reference indicators (70 degrees Celsius, 50%H2SO4 solution immersion 24 hours), and carbon steel, Japan imported similar steel, stainless steel corrosion resistance compared to higher than these steel grades. Products by domestic refineries and manufacturing units after the use of widely acclaimed, and achieved good results.
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
The difference between ERW (longitudinal resistance welding) and HFW (high frequency welding) is mainly due to the different principle.
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.
