Class 900 weld neck flange

class 900 weld neck flange

Industrial standards mainly demand for class 900 weld neck flanges mainly because of their high pressure tolerance. It is a product, that comprises of neck extension, with ends of a weld bevel. Wondering what is this bevel end’s functionality? It mainly is responsible for connecting it to pipe joints, that have similar bevels. Keep in mind that the connection types are of a V-type. This connection provided by the bevel end, provided circular weld uniformity around its perimeter, for also ensuring transition, that is unified.

This main functionality must be taken care with a serious note, as it is this part, which ensure the accurate and minimal restriction for the flow of fluid or gases. Hence, in piping applications, 900 LB weld neck flange provide natural connection.
But there are several use cases, that also demand for various testing standards before purchasing. To ensure this, below are some ideal testing methods that are ideally conducted for ANSI B16.5 class 900 welding neck flanges:

  • NDT: this testing standard covers for performance and quality aspects for products.
  • Eddy current testing: with the help of electronic probes, the faults or defects are detected by this testing methods.
  • Radioactive testing: for ensuring non-degraded performance, this testing method employs high frequency radioactive waves.

The above three testing methods not only install confidence for customers to choose products, but also enhance the product genuineness. This also builds a confidentiality between a supplier and customers. But it is always ideal to also take technical assistance before purchasing ASME B16.5 class 900 weld neck flange. Approach only those suppliers who provide true and accurate information for this product’s use case. When one needs to deal with corrosive saltwater, or harsh environments, this product wont cause any problems. This is because they perform good resistance to corrosion in such cases. This is why they are widely demanded in marine engineering and oil and gas industries.

Most importantly, be sure that the temperature range defined as per the standards ASME B16.5 is between -20-1000°F. In this temperature range the pressure must range between 2200-225 psi. If these factors are not being followed, there are chances of getting non-degraded performance, where cracks, losing strength can be seen.
