API 650 stainless and carbon steel tank carbon steel anchor straps

Service Conditions and Hydrogen-induced Cracking
When the service conditions might include the presence of hydrogen sulfide or other conditions that may promote hydrogen-induced cracking effects, particularly near the bottom of the API 650 stainless and carbon steel tank shell at the shell-to-bottom connections, care shall be taken to ensure that the materials and details of construction of the tank are adequate to resist hydrogen- induced cracking. The Purchaser shall consider restricting the sulphur content of the material to be stored through thickness testing of the steel, laboratory surveillance tests, and the use of internal tank coatings to reduce the possibility of hydrogen-induced cracking.

API 650 is constructed from carbon steel, austenitic duplex stainless steel, and API 650 stainless and carbon steel tank aluminium A Welding Certification is stipulated by American Society of Mechanical Engineers (ASME), Section 10. There is a required inspection, no third party. The inspection cost is the cost of the NDE.

In 2016, we brought our customer to visit our NM400 hot rolled plate; producing line and our shanghai warehouse for 30,000 tons plate and structure. As a result, Our client purchased 500 tons NM400 as first order, which is shipped by 3 times. In future. Our company will always guarantee that all the delivery condition for Hardox plate API 650 stainless and carbon steel tank provided will be with quenching and tempering, which is the best delivery type according GB/T 24186 standard.

In the event of continuous heavy rainfall, the inspection of the API 650 stainless and carbon steel tank farm should be strengthened to monitor and pay close attention to the soil moisture content of the tank farm in order to quickly take emergency measures. Check whether the seals of the oil unloading port and the oil measuring port are in good condition in time to prevent rainwater from leaking into the API 650 stainless and carbon steel tank from the oil unloading port and the oil measuring port, which will affect the oil quality.

Both parties shall confirm the API 650 stainless and carbon steel tank material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API 650 stainless and carbon steel tank steel plant.
