ISO 9001:2015

ISO 9001 is made up of 19 sets of standards for quality assurance in production, installation and servicing. This model applies to organizations that produce, install and service products. ISO expects organizations with the ISO registration to apply this model and to meet these requirements by developing a quality system.

ISO 9001 is a comprehensive set of requirements that governs the production of materials. The standard includes requirements that encompass all areas of production from the mill. A mill attaining ISO 9001 registry has a complete quality system in place. Compliance to ISO 9001 assures the customer that the material they receive consistently meets the most stringent quality standards.

NCA 3800 Nuclear Capability

NCA 3800 is a quality management process that ensures certified suppliers follow strict quality standards during production of pipe for nuclear uses. NCA 3800 requirements result in a comprehensive traceable report on processes and testing.

Pressure Equipment Directive (PED) Certification

The Pressure Equipment Directive (PED) is a set of European standards that govern the design, fabrication and use of pressure equipment. Conformance to this standard allows for the exportation of tubes and pipe through all of the EU member countries.

API Monogram

API Monogram is a voluntary licensing program that facilitates the consistent manufacturing of product that conforms to applicable API Specifications. Licensed manufacturers are given the authority to apply the API Monogram registered mark to equipment that meets the requirements.

Licensees demonstrate that they have a quality management system that is compliant with API Spec Q1 – an industry-leading quality management standard. API Spec Q1 meets most of the ISO 9001 requirements, in addition to requirements that are geared specifically for the oil and natural gas industry

API 5L Line Pipe
API 5L specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
