How can you prevent manufacturing defects in a JIS 5K flange?
Manufacturers build these components per Japanese Industrial Standards (i.e., JIS) published by the Japanese Standards Association. We are an established JIS 5K weld neck flange supplier in UAE capable of catering to pressure-piping systems and offshore vessels.
Modern production techniques with seamless inspection can avoid manufacturing defects like cracks, scaling, and inclusions. Strict tolerances and premium raw materials generate a consistent JIS 5K 200A flanges.
Which problems do buyers encounter when purchasing a JIS 5K weld neck flange?
The primary application of a JIS 5K 50A flanges is in petrochemicals, bitumen upgraders, and nuclear power. Buyers can acquire these products in nominal diameters of 10-1500. Common concerns are the non-availability of custom sizes, longer lead times, and high prices for a JIS 5K 40A flange. Inadequate quality control and testing are also rampant.
Our company has an expert in-house team to guide clients on product selection and appropriate usage.
How do you choose the pressure class for a JIS 5K slip on flange?
JIS standards encompass flanges from class 150 to 2500. The nominal pressure of a JIS 5K slip on flanges is 0.5MPa (5 kg-force/cm2). The pressure class depends on the temperature and the material also.

What is the proper surface finish for a Japanese standard 5K flanges?
The finishing of a Japanese standard 5K flanges adapts to buyer requirements, for instance, resistance to corrosion and high temperatures. We provide a stock finish for a JIS 5K 25A flanges or galvanisation and paint coatings (yellow, black, etc.). Some clients may order a specialised spiral serrated finish or grooves.
How do you ensure that JIS B2220 5K blind flanges meet dimensional tolerances?
Under this standard, the accepted tolerance for the outside diameter is +/- 1.5 to 3 mm (depending on flanges size). It ranges from + 1 to 3 mm for the inner diameter of JIS B2220 5K blind flanges. JIS also states limits for thickness, eccentricity, and pitch.
Buyers can verify these figures by inspecting the MTC, which offers step-wise traceability and certifies dimensional accuracy.
How do you ensure that a JIS 5K-100A flanges is rust-free?
Procure a JIS 5K-100A flanges in the appropriate material, say, stainless steel, for long-term rust resistance. A protective surface finish or galvanisation (hot/cold dip) is also dependable.
We also vouch for routine inspection and cleaning.
