Stainless steel fittings use SUS316 material and are of the double ferrule type, providing safe and reliable fittings. For more details, please download the catalog or contact us.
The M5 screw joint for 4X2 tubes has been made super compact. Made of SUS316. It has a simple structure consisting only of the main body and the bag nut, making tightening easy.
It has been developed to meet the needs for compactness. Currently, it is classified as a non-standard product. Made of SUS316, it has corrosion resistance and can be used over a wide temperature range from high to low temperatures. There are no abnormalities in the fittings until the tube breaks. *For more details, please contact us.*
No welding required at the pipe inlet and outlet! The panel union is screw-fastened, making it easy to create pipe inlets and outlets, contributing to cost reduction.
In machinery and equipment, it is common practice to weld pipe components to the plates of panels or housings at the inlet and outlet of piping, but this is a labor-intensive task. With a panel union, you simply pass it through a hole in the plate and screw it in place. Since it is clamped with a spring washer, there is no worry about it loosening. By installing it on a thin wall that cannot have screw holes cut, you can form a joint for other threaded piping. There are no screw holes. There is not enough thickness to cut screw holes. There is not enough strength to cut screw holes. You are welding round bars or Rc union fittings just to create screw holes. There are places where you want to secure R threads. We can solve these concerns. *For more details, please contact us.
CK solves the frustration of stainless steel screw fittings! "CK Pre-Seal SUS Fittings"
Stainless steel threaded fittings with excellent corrosion resistance are widely used in piping systems that require a hygienic environment. However, compared to iron pipe fittings (malleable), stainless steel threaded fittings often face issues such as "galling" and leakage, making reliable fitting products highly sought after. To address the problems that have arisen with conventional stainless steel threaded piping, our company has developed and launched the seal-equipped stainless steel threaded fitting "CK Pre-Seal SUS Fitting," which has received positive feedback from many customers.
This is a nipple fitting for a tube with an inner diameter of 1 mm. Made of SUS316. It has a simple structure consisting only of the main body and a bag nut. Despite being easy to tighten, it is airtight.
We have standardized fittings to meet the needs for 1mm inner diameter (3X1) tubes. They can be applied to silicone tubes and fluoropolymer (PFA, FEP, etc.) tubes. However, for fluoropolymer tubes, the pipe ends need to be slightly enlarged for installation. Made of SUS316, they are corrosion-resistant and can be used over a wide temperature range from high to low temperatures. There are no abnormalities in the fittings until the tube fails. *For more details, please contact us.*

For ship classification standard compliant pipe fittings, leave it to Benkan Kiko for stable supply!
There are pipe fittings manufactured using materials certified by classification societies, referred to as "classed products." These fittings are made from materials that meet the standards set by the classification societies, which are generally difficult to obtain. However, at Benkan Kiko, we leverage our extensive experience and material sourcing capabilities to provide stable supply support for our customers' design, procurement, and production needs. We can accommodate carbon steel, low-temperature steel, alloy steel, and stainless steel. We mainly support materials from the following five classification societies: 1. Nippon Kaiji Kyokai (NK) (KSTPT38, KLPB, KSTPA22, KSUS316LW, K304LTP, etc.) 2. Bureau Veritas (BV) (BV360, etc.) 3. DNV GL (DNV) (TS360, GL360, etc.) 4. Lloyd's Register (LR) (LR360, LR410, LR360LT, LR440, etc.) 5.

Are welded pipe fittings related to the RoHS directive? What about the certification?
What is the RoHS Directive? The RoHS (Restriction of Hazardous Substances, commonly known as RoHS) Directive is a directive enacted by the European Union (EU) in July 2006 that restricts the use of certain hazardous substances in electrical and electronic equipment. The RoHS Directive aims to ensure that electrical and electronic equipment does not contain hazardous substances, primarily to facilitate recycling under the WEEE Directive and to prevent harm to humans and the environment when such equipment is disposed of through landfill or incineration. Based on the official gazette published in June 2015, it has been decided that, starting from July 2019, four new types of phthalate esters will be added as restricted substances. *The WEEE (Waste Electrical and Electronic Equipment, commonly known as WEEE) Directive is a directive by the European Union (EU) concerning waste electrical and electronic products.

![[Case Study] Welded Pipe Fittings Made of Stainless Steel for General Piping in Hydroelectric Power Plants](https://image.mono.ipros.com/public/product/image/de2/2000404921/IPROS22724521797292153856.jpeg?w=280&h=280)
You have adopted welded pipe fittings made of stainless steel with excellent corrosion resistance.
The river water around the Yonago River No. 1 Power Plant in Suzaka City, Nagano Prefecture, has a strong acidity with a pH of 3.23, making it unsuitable for agricultural use and as a habitat for fish. However, in order to effectively utilize resources and contribute to the community while ensuring environmental conservation through profit return, the establishment of a hydroelectric power plant was initiated. In this context, we were approached through the Ipros site, and we had the opportunity to visit the site. We had detailed discussions to propose products that our company could assist with. As a result, we were evaluated positively for our extensive delivery track record to power plants, quality and inspection systems, and our ability to create documentation, leading to our adoption. The welded pipe fittings we supplied this time are made of stainless steel, model 90-45EL, material SUS304W, sizes 600A and 400A, with a thickness of S10S. We believe that stainless steel, which is highly resistant to corrosion, is essential for the river water with strong acidity used in hydroelectric power plants. In this way, Benkan Kiko's welded pipe fittings are used in various places.
