Fluid transport pipeline,API 5L Linepipe


Fluid transport pipeline API SPEC 5L-2007 line pipe

1, line pipe profile

Fluid transport pipeline,API 5L Linepipe

Pipeline specifications :8-1240 × 1-200mm
Uses: used in oil and gas industry, gas, water, oil transportation
line Standard: API SPEC 5L
GB/T9711-- Chinese national standard
API SPEC 5L - American Petroleum Institute Standard < / DIV>
API SPEC 5L-2007 (line pipe specification), the American Petroleum Institute compiled and published around the world, Universal. Pipeline: the shaft out of the ground, oil, gas or water through the pipeline to pipe oil and gas industry enterprises. Line pipe including seamless and welded pipe two pipe ends plain end, threaded end and socket end; its connection to end welding, coupling, socket connections. The pipes are mainly made of B, X42, X46, X56, X65, X70 and other steel grade. My company in August 2009 by the U.S. API certification (API 5CT and API 5L).
mainly produce steel grades:
B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485 2, line pipe size tolerance:
