Buy male threaded blind flange and alloy steel screwed flange in class 150 to 2500. View NPT threaded slip on flange price in the GCC countries

Varying price variations occur for both the flanges; as per the class 150-2500 pressure rating condition. One of the main reason for this is its mode of application, under the class of working pressure. When dealing with male threaded flanges, they cannot be easily cut. Hence they are not recommended for pipe systems, which demand for thin wall thickness flanges. But extensive use case is seen for flange which are screwed; in pipes which are small in size. Hence, be very clear on the working standards/requirements and then choose your desired products. Best origin is to purchase it from GCC countries for choosing male threaded blind flanges.

Still starching your head, to search for the testing standard and top notch quality screwed flange? Why not approach the listed suppliers of pipingmaterial.ae; where you would find:

Beneficial customers; who get only genuine, trusted and verified suppliers. Here, they are also technically knowledgeable to guide the customers to eradicate any confusions or issues to suffice industrial standards.

For customers checking out prior delivery? Check out the contact details of the suppliers.

To compare the pricing, this B2B platform has limited suppliers. This is done to provide efficiency for the customers to check for the comparison of pricing from different suppliers.

These are some of the prime reasons why customers and wide industrial standards have proven this platform to be one of the well-reputed threaded flanges suppliers in UAE.

Before purchasing, it is important for industrial standards to also keep a check on the manufacturing mode of CS threaded flanges. It is composed of max 0.35% contents of carbon, with 0.6-1.05 % of manganese contents added. Other than this, the pressure ratings for this material is specified under the class 150, 300, 400, 600, 900, 1500 and 2500. This specification is done for the temperature range -29-5280C. Hence, there are variations in price range based on the composition mode. So, it is advised to the customers to approach listed suppliers and manufactures to get quotations for the same.
