ASTM A671/672/691 Pipes provides great resistance against corrosion and wear/ tear in the heavy-duty pipeline fittings. ASTM A671/672/691 is best known for its ultimate strength and offers high service to reducing environments. These are excellent pipes applied for extended services in the industrial piping applications. The Champ Steels are offering the extensive range of ASTM pipes in different grade materials, standards, specifications, designations, different dimensions, shapes, sizes. We provide tested and qualified products so that all the products will meet the set industrial norms.
ASTM A671/672/691 is originally designed to withstand environments containing dilute sulfuric acid, and other harsh chemical compounds. It is one of the few grades that offer service at higher temperatures. These pipes offer complete resistance in such environments that contain a higher concentration range up to 0 to 100%. This grade offers good resistance to a number of other inorganic acids.
These pipes are resistive to chloride stress corrosion cracking under certain conditions. These pipes have resistance to SSC (stress corrosion cracking) due to the increases alloying elements.
Quality and approvals:
Our quality inspection department is facilitated with accurate measurement tools and inspection machines for efficient readings and results. Thus this allows them to detect fine errors in the production level. These parameters make us capable to offer unbeatable quality products to the customers. The tests followed by them are material tests such as intergranular corrosion test, pitting corrosion test, radiographic test, positive material test, flaring test, macro test, micro test and more. The strength and impact tests are Mechanical test, leakage test, hardness test, compression test, tensile test, chemical test, flattening test, ultrasonic test, etc.
Credentials reports are offered by us:
The material test report is made as per EN 10204 3.1 or 3.2. Those are fumigation certificates, quality assurance plan, heat treatment charts, raw material test report, attested certificate by third parties, mill test report, stamping details. Other certificates are Commercial invoice, specification guide, hardness details after heat treatment, welding guide, packing list, NABL test report, etc.
