A573 grade 58 plates API Std 650 tanks

Impact Test Requirements for Oil storage tanks Primary Components
All API Std 650 tanks primary components of 9% or 5% nickel steel shall be impact tested in accordance with Q.2.2.2 through Q.2.2.4. Impact testing is not required for primary components of austenitic stainless steel, nickel alloy, and aluminum materials. Welds in high-alloy (austenitic) stainless steel shall be impact tested if required by Q.6.3.
Impact testing of plates, including structural members made of plate, shall comply with the following:a)Impact test specimens shall be taken transverse to the direction of final plate rolling. b)Charpy V-notch specimens shall be cooled to a temperature of –320°F for A353, A553, and A645 steels for impact testing.

The effect of air pressure on the API Std 650 tanks tank walls of the API 650 tank must be considered when the design pressure is greater than 2 kPa.The fixed point method can be used to design the tank wall of atmospheric or micro internal pressure API Std 650 tanks storage tank.

On September 14th 2019, a Australia customer purchased 500 tonsDIN17155 15Mo3 boiler steel plates, which will be used for vessel modification of wax backflow protection project and LPU project. Many old customers keep asking about Din17155 steel grade-15Mo3. Usually our company would suggest customers to choose EN10028 steel specification, but if customer insiste on the old steel grade, we could arrange it either. With years of experience in produceing DIN 17155 15Mo3 boiler steel plates, the company supplies high quality steel API Std 650 tanks product with low cost and better service.

To scientifically evaluate the remaining service life of the API Std 650 tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API Std 650 tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API Std 650 tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel.
