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 big is the seamless steel tube of DN50?
Domestic steel pipe diameter is generally divided into A series and B series, DN50 pipe diameter of 60mm and 57mm respectively, the wall thickness should be based on your design pressure, temperature, pipe material to calculate.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Butt fastener: used for connecting two steel pipe jointsThin-walled stainless steel pipe, the national standard consists of three parts, respectively on the thin stainless steel pipe connection, the sealing ring of raw materials of various specifications of O type thin wall stainless steel pipe diameter and wall thickness of pipe and rubber have clear requirements, in order to ensure the quality of the whole pipeline, pipeline safety and guarantee system durability. The connection mode is clamp type and ring type.
Q:What's the material of Q325 steel pipe?
In terms of deoxidation methods, F, B, Z can be expressed as boiling steel, flat killed steel, killed steel and boiling steel. They are deoxidized steel, which is of poor plasticity and toughness. Welded joints made of this material are susceptible to cracks when subjected to dynamic loads. Should not work at low temperatures, sometimes hardening. In contrast, calming steel is excellent and uniform, with good plasticity and toughness.
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:What are the uses of welded steel pipes?
Straight seam welded steel pipe (YB242-63) is a steel pipe whose welding seam is parallel to the steel tube. Usually divided into metric welded steel pipe, welded thin-walled pipe, transformer, cooling tubing, and so on.
Q:What does "buried steel pipe" 6*2SC100 mean?
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:Galvanized steel pipe DN100 and SC100
Zinc plating, hot dip galvanizing and cold galvanizing, to see the design instructions and design requirements, which will explain
Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
Pile: refers to the use of hammer piling method and pile vibration method, steel casing with valve type pile tip or precast reinforced concrete pile boots into the soil, then pouring concrete (or first in the tube into the cage), while hammering or vibration of a pile side pull tube. The former is called hammer sinking pipe cast-in-place pile, and the latter is called vibrating sinking pipe cast-in-place pile.
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The thread of the tightening (JDG) joint is unified with an outer thread, a wall thickness of 1.5mm, and a button (KBG). The thread of the joint is an internal thread, and the wall thickness is 1.0mm. Withholding type joint for the use of the same company and pipe connection to matching products with complete connection clamp buckle. Fastening and pressing type correctly connected and locked after no need to do a cross ground.
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.
