ASTM A 691 Grade Pipes

ASTM A 691 Grade Pipes are the most important tool in various industries. They are at the forefront of the operations in oil, natural gas and petroleum sector which is the reason behind these businesses being extra cautious while ordering ASTM A 691 Grade Pipes. They look for strong and durable pipes which can withstand high temperature and pressure. They place a huge emphasis on the quality and one of the benchmarks for judging pipe quality is API hallmark. API or American Petroleum Institute, the largest petroleum and natural gas industry association of the United States, has given some specific guidelines for the transportation of oil, water, and gas. The ASTM A 691 Grade Pipes conforms to these guidelines and therefore, they are trusted by consumers.

ASTM A 691 Grade Pipes further adheres to the International Organization for Standardization ISO 3183 and it specifies the production of two product specification levels (PSLs): PSL1 and PSL 2. The former is a standard quality for line pipe whereas the latter carries additional mechanical, chemical properties, and testing requirements.ASTM A 691 Grade Pipes is a recognized and trusted name for businesses operating in the oil, natural gas, and petroleum sector as well as other sectors where ASTM A 691 Grade Pipes are required to carry out operations.
