Stainless steel ASME B16.47 slip on flange
We has 36 years manufacture experiences, who export all kinds of flanges and pipe fitting to all over the world. Stainless steel ASME B16.47 slip on flange is a type of so flange which is according to the standard for large-caliber flanges, including cl75-cl900 NPS26 to NPS60 under pressure levels.
Important application of Stainless steel ASME B16.47 slip on flange in industry
Stainless steel ASME B16.47 slip on flange, the large-diameter flat welding flange Not only save space, reduce weight, more importantly, to ensure that the joint site will not leak, with good sealing performance. The reduced size of the compact flange is due to a reduction in the diameter of the seal, which reduces the cross-section of the sealing surface. Secondly, the flange gasket has been replaced by the sealing ring to ensure the sealing face matching. As a result, it only takes a little pressure to press the cover tightly. With the reduction of the required pressure, the size and quantity of bolts can be reduced correspondingly, so a new product with small size and lighter weight (less weight 70%~80% than traditional flange) is designed.
Therefore, Stainless steel ASME B16.47 slip on flange is a type of relatively high-quality flange products, to reduce the quality and space, the industrial use played an important role. Large-aperture flat welding flanges are widely used in the connection of medium and low pressure vessels and pipelines. The flat welding flange of the vessel can be divided into type A and B. A slip on flange structure is a common ring plate. B-type flat welding flange except ring plate with a short and thick tube section, after welding the sealing surface, and the method Lan in conjunction with the short section of the ladder-shaped groove (equivalent to socket welding flange), to ensure the quality of welding, so good sealing performance, used for high sealing requirements of the occasion, design in accordance with the overall type of flange check.
