API 650 unanchored flat-bottom tank piping and forgings

The API 650 petroleum storage tank standard is one of the most widely used design specifications. It is the API 650 standard of the American Petroleum Institute. The main goal of the API 650 standard is to promote the purchase and construction of vertical, above-ground, and welded manufacturing API 650 unanchored flat-bottom tank tanks through the requirements contained in its parts to ensure that the required safety regulations are met.

Strictly control the welding groove forming of API 650 unanchored flat-bottom tank: in order to ensure the geometric dimension of assembly and good welding of welding seam, before hoisting and laying, the edge of all metal vertical storage tank plate shall be polished by grinder, and the flatness of plate shall be ensured according to the design requirements. Strictly control the size of API 650 unanchored flat-bottom tank weld assembly: measures must be taken to strictly control the assembly size of metal vertical tank bottom plate during assembly.

Inspection of Butt-welds in Piping
Butt-welds in piping and in API 650 unanchored flat-bottom tank pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.

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.
