Installation and maintenance of stainless steel manways in oil tank
Commonly used in pipes and equipments, stainless steel manways are a convenient access for people to go in and out. The Flange manways is more common in terms of material, carbon Pressure Manways and stainless steel manways. The local environment of stainless steel manways application is relatively harsh, and the risk factor is also higher. Therefore, the most important thing for stainless steel manways is that its corrosion resistance is extremely excellent. Wenzhou Likemetals Co., Ltd., as a manways supplier, with excellent quality, competitive price, fast delivery, we believe we can meet your needs.
The inner side of the first pressure ring and the second pressure ring of the stainless steel manways are sequentially equipped with a bead and a wire mesh, and between the two wires are filled with heat insulating material and constitute a plug. It can ensure the isolation of high temperature medium and thermal insulation performance under working conditions; and also can reduce the influence of a small amount of leakage high temperature medium on the manways, and can reliably seal and close the manways under high temperature conditions and reliably open or close under cooling condition. As a main accessories,Stainless steel manways are often used in oil tanks. Therefore, let’s understand the installation and maintenance of the manways in tanks.
Since the stainless steel manways are located in the lower part of the tank, the manways are subjected to a large liquid pressure. In order to prevent leakage, we must be strict with installation quality. Sealed waterlines are processed on the flanges and covers, and attention should be paid during construction to avoid oil leakage during use. Mark each time when you remove the manways, so as to avoid misplacement when reloading, which will affect the tightness. When installing nuts on the manways cover, apply even force to the opposite corners to prevent oil leakage caused by covers deformation or uneven force.
