Problems with blast discs in gas pipelines
Thread Content
What should be the bursting pressure of the burst disc at the end of the main pipe in the coke oven basement? What is the material? How thick is it? On previous drawings, lead plates with a thickness of 6 mm and aluminum plates with a thickness of 2 mm were generally used, with a burst pressure of 0.08 MPa. On current drawings or labels, the materials are indicated using letters and numbers (such as 316L/F46/316L), and the burst pressure is 0.035 MPa. It doesn’t really matter what material is used; what’s unclear is why the burst pressure has decreased from 0.08 MPa to 0.035 MPa
Regarding the issue of burst discs for gas pipelines, based on the information you provided, for the burst discs at the ends of the main pipes in the coke oven basement, the materials specified in previous drawings were 6 mm thick lead plates or 2 mm thick aluminum plates, with a burst pressure of 0.08 MPa. Current drawings or nameplate materials are often denoted by letters and numbers (such as 316L/F46/316L), with a burst pressure of 0.035 MPa. This shows that modern manufacturing techniques and materials have been improved, enabling them to withstand lower blasting pressures as well as offering better corrosion resistance and other advantages. As for which specific material to use and its thickness, it needs to be evaluated and chosen based on the specific circumstances. .
