Erosion and Corrosion in Pipeline for Sea Water – Part 1

INTRODUCTION Marine problems are of national importance• At the present time, the U# S* Government is stimulating interest in marine activities in many areas. Examples of problems receiving attention are shore erosion, harbor protection, sea-water intrusion of the fresh-water table, navigation, underwater transportation, oceanographic exploration, hydrofoil ships, nuclear-powered vessels, iceberg movements, seafood, pollution control, etc* One program which has gained national and international interest is that of the Office of Saline Water to develop methods of converting sea or brackish water to fresh water. For highly saline waters, such as sea water and brines from salt wells, many today favor […]

REPORT ON PROPERTIES OF AN A 106 GR.B CARBON STEEL PIPE

Engineering Research Institute  THE UNIVERSITY OF MICHIGAN Ann Arbor. Mich. The investigation covered by this report was made to evaluate the tensile and rupture properties of ASTM-A106, Grade B, carbon steel pipe. It was carried out as the Timken Roller Bearing Company^ contribution to a cooperative program of Petroleum and Chemical Panel of the ASTM-ASME Joint Committee on Effect of Temperature on the Properties of Metals# Several organizations evaluated typical samples of carbon steel in plate and pipe form to establish typical properties for carbon steel products. Stress-rupture properties were measured at 1000#F and short-time tensile properties at 80°, 200#, 400#, […]

How does the casing pipe work ? Choose your casing tubing !

Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts through the rock formations and allows drilling engineers to reach the reservoir below, the raw sides of the well cannot support themselves. Similar to the bones of your spine protecting the spinal cord, casing is tubing that is set inside the drilled well to protect and support the ABTER STEEL. You can choose the oil casing to use, select the casing size range as follows: Standard: API 5CT Steel Grade: J55, K55, N80, L80, C90, T95, P110, Q125, V150 Dimension: 4 1/2″–20″ Connection: BTC, STC, LTC * P – […]
