120ft diameter API 650 vertical welded storage tanks

It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation.

The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API 650 vertical welded storage tanks manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.The API 650 specification provides guidelines for the API 650 vertical welded storage tanks design, manufacturing, materials, installation and inspection of welded vertical and cylindrical tanks. Such containers must be on the ground and have a closed or open top.Since its inception, the company has always adhered to the development policy of "survival with quality, development with products, cooperation with credibility, and service with customers". I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! And sincerely hope to establish a long-term cooperative relationship with them, mutual benefit and common development.The cone slope of the completed API 650 vertical welded storage tanks foundation is 15/1000 for the general foundation and less than 35/1000 for the soft foundation. After the foundation settlement of the storage tank is basically stable, the surface slope must be greater than eight thousandths. The edge of the tank bottom should be more than 0.3 meters higher than the surrounding ground. Above the ground, the tank bottom leakage detection tube should be drawn from the foundation sand cushion and cross the foundation ring wall or the slope protection surface. The circumferential distance should be less than 20 meters, and each API 650 vertical welded storage tanks should have at least 4 detection tubes.
