The theoretical weight of steels is obtained by calculating nominal dimensions and density (which is called specific weight in the past). This is directly related with the steel length, the cross section area, and the allowable size deviation. Because of the allowable deviation in the process of manufacturing, the calculated theoretical weight is somehow different from the actual value, and the theoretical value is only for reference while estimating. The fundamental equation is as follows: Steel pipe single meter weight calculation (kg / m): W = (outer diameter – wall thickness) * wall thickness * 0.02466 = 2408 * 12 * 0.02466 […]

ABSTRACT The corrosion resistances of enamel-coated steel pipe in 3.5 wt% NaCl solution was evaluated and compared with those of epoxy-coated pipe using open-circuit potential, linear po- larization resistance, and electrochemical impedance spectros- copy tests. T-001c enamel slurry and GP2118 enamel powder were sprayed to steel pipe in wet and electrostatic processes, respectively. The phase composition and microstructures of the two enamels were characterized with x-ray diffraction and scanning electron microscopy (SEM). The surface roughness of enamels and their bond strength with steel substrates were quantified to understand coating quality. SEM images revealed that both types of enamel coatings have […]

In recent years, with the decreasing number of easily exploitable oil and gas wells, it has become necessary for oil and gas wells to go deeper on both underground and underwater. And, tubing and casing strings are subjected to higher temperature and higher pressure in these wells, which would probably cause casing failure or gas leakage in the high-pressure/high-temperature (HPHT) wells. Hence, more attention has been paid to wellbore integrity in oil and gas industry in recent years.1,2 The key factor of wellbore integrity is casing string connections, which are expected to provide both structural and leakage integrity under severe environment. […]

Properties of Galvanized Steel Pipe Welds Galvanizing has been used to protect iron and steel from rusting for over a hundred years in places as diverse as the wire rope used for the suspension cables on the Brooklyn Bridge to gutters on houses. Galvanizing is simply coating of zinc over steel. Like paint, galvanizing protects steel from rusting by forming a barrier between the steel and the environment, but galvanizing goes one giant step further than paint — it also provides electrochemical protection of the steel. Since zinc is electrochemically more reactive than steel, it oxidizes to protect the steel […]

Why not galvanizing after welding Why not avoid the whole problem of welding galvanized steel pipe sheets after galvanizing? After all, steel products are always galvanized after manufacture, because there has been no practical way to restore the galvanizing effect after welding. Zinc plating after manufacture is still conventional, but must be done with great care. The manufacturing must be cleaned in acid, the acid must be neutralized, and then made into a liquid zinc can that must be immersed in excess of 900 °F. People must be very careful to make it dry when it is put into zinc, […]

M. N. Ervina Efzan*, S. Kesahvanveraragu, J. Emerson 1.0 INTRODUCTION 1.1 Offshore Pipeline Material Pipelines in offshore platform are made up of various types of materials. Selection of material relies upon certain considerations such as cost, functional requirement, operating conditions of pressure and temperature, corrosion rate and so forth [1-2]. Since there are varieties of pipelines in offshore platform, material selection and those considerations are highly required. In offshore industry, metal is the highly used material that can be assorted into ferrous and non-ferrous metals [1-3]. Metals containing iron (Fe) as their premier composition are known as ferrous metals, whereas metals containing other elements are termed as non-ferrous […]
