API standard 650 stainless and carbon steel tank gauging wells

Butt-welded joints used to fabricate large steel storage tank fittings shall be completely radiographed. Lines carrying liquid shall be hydrostatically or pneumatically pressurized at a minimum pressure of 35 lbf/in.2 and API standard 650 stainless and carbon steel tank butt welded joints shall be simultaneously visually examined (hydrostatic) or solution film tested (pneumatic) for tightness. If manufactured pipe has been hydrostatically tested previously to ASTM requirements, then only circumferential welds need to be examined.BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API standard 650 stainless and carbon steel tank oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.We supply 3500 tons SA387GR5CL1 steel plates to Pakistan. The main businesses of the Pakistan customer are manufacturing columns & towers, heat exchanger, waste heat recovery boiler, pressure vessel & reactors, tanks, etc. We arranged SGS test for the SA387GR5CL1 steel plates. The test contents include chemical composition analysis, tensile test, impact test, etc. The test results are satisfied. The Pakistan customer gave good feedback after receiving the SA387GR5CL1 steel plates.The water dissolved in the oil will be separated out from the oil stored in the API standard 650 stainless and carbon steel tank for a long time, and the acidic water layer will appear at the bottom of the API standard 650 stainless and carbon steel tank for a long time, which will accelerate the corrosion of the API standard 650 stainless and carbon steel tank and cause the wall thinning and even leakage. With the increase of service life, the API standard 650 stainless and carbon steel tank must be inspected and cleaned regularly to check the hidden danger.The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel.
