Prefabrication requirements of large vertical large steel tanks API620 for sale accessories: the prefabrication shall be deepened as far as possible in strict accordance with the requirements of construction drawings and specifications, according to the principle of convenient installation and construction, as much as possible to reduce the installation workload, especially the workload of high-altitude operation. The prefabricated accessories shall be strictly inspected to ensure the quality and make marks. In addition, effective measures should be taken to prevent deformation, damage and corrosion during storage, transportation and stacking on site

API 620 Tank Standard Post-heat Treatment (Stress Relief)
The post-heat treatment now performed on pressure vessels is of established value, although the mechanism by which the improvement is realized may be open to debate. Post-heat treatment of large steel tanks API620 for sale tank sections when the plate thickness exceeds 11/4 in. is required as stated in 5.25. In special cases, the possibilities of post-heat treatment after erection should be explored. Post-heating an insulated tank may be possible if an ample source of heat is readily available and if the rigidity of the tank is adequate.
The thermal stress-relief treatment performed on pressure vessels is recognized as a means for reducing the probability of brittle failures.

According to API Standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the large steel tanks API620 for sale tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to large steel tanks API620 for sale ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.

In December of 2015, our regular India customer sent us an inquiry for large steel tanks API620 for sale pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
