Home > Laboratories > Pipeline Materials Laboratory


The Pipeline Material Lab (PMLThe Pipeline Material Lab (PML) has a history of nearly three decades. Founded in 1981, the Petroleum Tubular Goods Test Center is the predecessor of TGRC as well as the foundation for the development of the discipline of petroleum pipeline engineering. NELOGPTS established PML based on TGRC in April 2009, which is of great significance to the development of the professional field. To fulfill relevant tasks, further strengthen laboratory organization and leadership, and cement communication and coordination with the main laboratory, TGRC has determined the director and deputy directors, adjusted staff, defined their responsibilities and established a work system, laying the groundwork for the smooth implementation of the laboratory's tasks for the next stage.

Orientation: A test base for petroleum tubular engineering material property research and detection that carries out basic application research and advance technology reserves in the field of oil & gas pipeline engineering materials, and resolves frontier technologies, bottleneck problems and generic problems.

Key tasks: Increasing the safe reliability of pipeline materials, fulfilling relevant research projects, researching on key technologies, studying and formulating major technical standards, gathering and training pipeline material innovation talents on the basis of the need of oil & gas transportation pipeline engineering construction. Earnestly organizing projects underway, and furthering the key applied technology research of X80 pipe line steel based on the major technological project of Phase 2 of Line 2 of China West-East Gas Pipeline Project, including X80 steel pipe gas explosion test, the impact of strain ageing and high yield-tensile ratio of X80 steel on pipeline safety, and large-deformation steel pipes for areas subject to strain design; forming systematic X80 pipeline steel and steel pipe application technologies and standards to provide technical support for future pipeline construction. Studying key technical indicators, technical conditions and manufacturing processes in X100 line pipe, pipe fitting and bent pipe development and application, laying the technical foundation for the application of X100 pipeline steel in small projects; and carrying out basic research on X120 pipeline steel application and advance technology reserves for future high-pressure gas pipeline projects.

PML's staff includes researchers, technical supervisors, testers, equipment operators and auxiliary testers. Apart from R & D staff and technical directors who should have high comprehensive quality, chief equipment operators, testers and auxiliary testers have attended corresponding trainings and been certified through qualification assessment.
PML has a director and two deputy directors, 22 R & D and technical directors, and eight testers and equipment operators; four professor-level senior engineers, seven senior engineers, 15 engineers and six assistant engineers; eight doctors, 12 masters and seven bachelors (master candidates); as well as two senior experts and two young experts of TGRC.

In daily operation management, PML practices the system of director responsibility, operates on the basis of the transport pipe and pipeline research center and the technical supervision center, has determined researchers and technical directors, has built an echelon of laboratory managers, technical experts, equipment engineers, testers (operators) and auxiliary testers, and has formulated the laboratory management regulations in accordance with the Measures for the Management of the National Engineering Laboratory of Oil & Gas Pipeline Transportation Safety, thus ensuring the effective daily operation of the laboratory.

Iconic equipments

Large energy pendulum bob impact test system

Large energy pendulum bob impact test system is mainly used for testing and analyzing the fracture characteristics of high-grade steel line pipe. It includes high i mpact energy measurements and high breaking speed/time measurement, can be used for expenment of conventional drop weight tear and research of crack dynamic expanding and arrest.

Axial compression - bending composite large deformation experimental system

Axial compression - bending composite large deformation experimental system can achieve a real objective evaluation of the overall deformation capacity of steel pipes with large deformation, enhancing the safety and reliability of the pipeline. There is not a similar device yet like this system, which fill the blank of steel pipe large deformation expenmental system in domestic market.
