We would like to introduce our case studies on stainless steel tank and filter housing manufacturing. For parts of stainless steel pressure vessels and tanks where buff polishing is difficult or costly, we can achieve cost reduction by opting for electropolishing instead of buff polishing. Please feel free to contact us when you need our services. 【Key Points of the Case】 ■ Since buff polishing tends to be high-cost and may have areas that are difficult to process, we can reduce costs and shorten lead times by selecting electropolishing for areas where buff polishing is not necessary for the product's functionality. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our case studies on the production of stainless steel tanks and filter housings. By designing the legs of stainless steel pressure vessels and tanks to extend vertically from the bottom plate, we can reduce the man-hours required during production, thereby achieving cost reductions. When installed vertically, unlike angled installations, stable mounting is possible, which significantly shortens production time. 【Key Points of the Case Studies】 - By designing the legs of stainless steel pressure vessels and tanks to extend vertically from the bottom plate, unless otherwise specified, we can reduce man-hours and production time, achieving cost reductions. - Since the dimensions of the legs can be determined and installation can be easily performed, product quality is also improved. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our examples of stainless steel tank and filter housing manufacturing. When welding PS sockets to stainless steel pressure vessels and tanks, it is important to choose thick-walled sockets rather than thin-walled ones. Thick-walled PS sockets can suppress deformation due to thermal effects and operate stably without issues even during pressure testing. [Key Points of the Case] - Thin-walled PS sockets are prone to warping due to heat during welding, which can deform the threaded part and lead to leaks after screwing in. - By selecting thick-walled sockets, such troubles can be prevented, ensuring stable product quality. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our case studies on the production of stainless steel tanks and filter housings. When there is no need to align the pressure gauge displays horizontally, arranging the pressure gauges of stainless steel pressure vessels vertically can significantly reduce labor and costs. In this case, we select pressure gauges with connection ports on the back and connect them to the tank body with a socket. This eliminates the need for processes such as pipe fabrication, allowing for quick production. [Key Points of the Case] - If there is no necessity to align the pressure gauge displays horizontally, adopting pressure gauges with back connection ports and arranging the gauges vertically can lead to significant cost reductions. - It is also possible to reduce the pipes connecting the pressure vessel and pressure gauge, which helps decrease the number of components. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our case studies of stainless steel tank and filter housing manufacturing. If the nameplate for stainless steel pressure vessels or tanks is not required by specifications, we can eliminate the need for a nameplate holder and instead use a sticker or similar, which can be affixed directly to the body of the pressure vessel or tank. This approach reduces costs and shortens lead times by avoiding the custom manufacturing of nameplate holders. Please feel free to contact us when you need our services. [Key Points of the Case] - Nameplate holders need to be custom-made each time according to the use of the nameplate, which leads to increased costs. - If nameplate holders are unnecessary, we can change the nameplate to a seal format and affix it directly to the pressure vessel or tank body, achieving cost reduction. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce examples of our stainless steel tank and filter housing manufacturing. By designing the fastening parts of stainless steel pressure vessels and tank lids with standard hex nuts instead of eye nuts, it is possible to achieve cost reduction. Additionally, since hex nuts can be used with tools like monkey wrenches, work efficiency is generally improved. For suspension, using only the necessary eye bolts can also lead to cost savings. 【Key Points of the Example】 - Eye nuts are a commonly used fastening method for stainless steel pressure vessels and tanks due to their versatility with specified tools and during suspension, but the components are expensive, leading to increased costs. - By minimizing the use of eye nuts and using hex bolts, which are priced at less than one-tenth of the cost, it is possible to reduce expenses. *For more details, please refer to the PDF document or feel free to contact us.
