Introduction to the production data and process of double-layer oil tanks for skid-mounted gas station

In the normal operation of skid-mounted gas stations, in addition to having a clear understanding of its basic operating procedures and precautions, we also have to have a certain understanding of its basic knowledge. Today, we will popularize the basic data and basic process of the processing and design of the double-layer oil tank, the main component of the skid-mounted gas station.

I. Production process.

1. Processing head: material acceptance -> size cutting -> cleaning and scraping welds -> joints -> forming -> inspection -> welding reinforcement ribs -> inspection.

2. Tank body: material acceptance -> size cutting -> cleaning and scraping welds -> pre-rolling -> welding -> roundness calibration -> inspection.

3. Tank body assembly: head and cylinder segment welding -> each cylinder segment butt joint -> welding -> inspection -> spot reinforcement plate and reinforcement ribs -> inspection -> welding -> inspection.

4. Assembling parts: welding support -> inspection -> marking hole position line -> inspection -> welding manhole and each pipe -> inspection.

II. Requirements for oil tank molding and welding.

When welding the cylinder body, add a steel ring support ring inside the cylinder segment.

1. Tank body butt misalignment: A seam <= 1mm, B seam <= 1.5mm.

2. Welding angle: A seam <= 2.6mm, B seam <= 1mm.

3. Cylinder roundness: maximum diameter and minimum diameter >= -10mm and <= 10mm.

4. Cylinder straightness: <= 5mm.

III. Welding.

The weld is required to be smooth and straight, without defects such as cracks, pores, arc pits, undercuts, and weld nodules.

1. The end cover joint is welded by manual welding or submerged arc welding, the welding material is J506 or H10Mn2, weld width < 10mm, and the weld height is <= 2mm.

2. The cylinder weld is welded by manual welding or submerged arc welding, the welding material is J506 or H10Mn2, the weld width is < 10mm, and the weld height is <= 2mm.

3. The reinforcement plate is welded by manual welding, the welding material is J506, and the weld angle height is 5mm.

4. The reinforcement is welded by carbon dioxide gas shielded welding, the welding material is H08Mn2SiA, and the weld angle height is 5mm.

5. The support is welded by manual welding or carbon dioxide gas shielded welding, the welding material is J422 or H08MnSi (the welding with the tank body must be J506 or H08Mn2SiA), and the enterprise is convenient for gas stations.

The above is the production data and process introduction of double-layer oil tanks in skid-mounted gas station. Understanding the basic knowledge is very important for us to better operate skid-mounted gas stations.
