Product specification and description
In the petroleum field, nickel alloy pipe is mainly used in oil well pipe, fracturing pipe, etc. In the field of chemical industry, nickel alloy tubes are mainly used in the production of various pressure vessels, pipelines, pumps, etc. In the Marine field, nickel alloy tubes are mainly used in seawater desalination, Marine engineering, offshore platforms and other fields.
In addition, nickel alloy tubes can also be used in nuclear power, thermal power generation, shipbuilding, seawater desalination and other industries, in these fields can play its excellent corrosion resistance and mechanical properties.
Our inspection of steel pipes generally includes: inspection of geometric size and surface quality: inspection of chemical composition, mechanical properties, technological properties, inspection of high-low tissue: non-destructive testing: inspection of some special properties and length measurement and weighing.
(1) Check the geometric size of the steel pipe
The outer diameter, wall thickness, bending degree and length of the steel pipe are checked on the inspection table with external calipers, micrometers, bending degree and length winding.
Sometimes, the outer diameter, wall thickness and length are also continuously tested by automatic size detection devices (such as automatic diameter measurement, thickness measurement, length measurement devices). For OCTG steel pipe also need to check the thread parameters.
(2) Check the inner and outer surfaces of the steel pipe
We generally use visual inspection for internal and external surface inspection, and in addition to visual inspection, the internal surface is also inspected by reflection prism. Some special purpose steel pipes also require non-destructive testing, including eddy current, magnetic leakage, ultrasonic, magnetic particle testing, etc., to check the quality of the inner and outer surface of the steel pipe.
(3) Mechanical properties and process performance inspection
In order to verify that the mechanical properties of the steel pipe meet the requirements of the standard, we need to conduct mechanical properties inspection on the steel pipe sampling.
The test of mechanical properties mainly includes tensile strength, yield strength, elongation, impact work, etc. The process performance test mainly includes flattening test, flaring test, water pressure test, flange test, cold bending test, perforating test and so on. These inspection items are selected according to the different standards and the difference in the use of the steel pipe.
(4) Non-destructive inspection
Our non-destructive testing methods include: magnetic leakage testing, ultrasonic testing, eddy current and fluorescent magnetic particle testing, ultrasonic spectrum analysis testing, ultrasonic imaging testing and ultrasonic high temperature testing
Material introduction
Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties.
Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%. Most commonly, the phrase "alloy steel" refers to low-alloy steels.
Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type) and nothing else (excepting negligible traces via slight impurities); these are called carbon steels. However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (Mn) (the most common one), nickel (Ni), chromium (Cr), molybdenum (Mo), vanadium (V), silicon (Si), and boron (B). Less common alloyants include aluminium (Al), cobalt (Co), copper (Cu), cerium (Ce), niobium (Nb), titanium (Ti), tungsten (W), tin (Sn), zinc (Zn), lead (Pb), and zirconium (Zr).
The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. To achieve some of these improved properties the metal may require heat treating.
Although alloy steels have been made for centuries, their metallurgy was not well understood until the advancing chemical science of the nineteenth century revealed their compositions. Alloy steels from earlier times were expensive luxuries made on the model of "secret recipes" and forged into such tools as knives and swords. Modern alloy steels of the machine age were developed as improved tool steels and as newly available stainless steels. Today alloy steels find uses in a wide array of applications, from everyday hand tools and flatware to highly demanding applications such as in the turbine blades of jet engines and in nuclear reactors.
