Fastube seamless tubing is used for delivering the oiland gas to the ground from well bottom. In order to suit each customer’s needs, we offer non-upset tubing(NU), external upset tubing(EU) and integral joint tubing(IJ).

Both ends of our oil tubing are threaded, and guard ring is used to protect thethread of tubing and joint. Our seamless tubing blank is made by Fastube Dingyuan Precision SteelPipe Company, which is dedicated to constant product improvement. As a result efforts,the tubing blank removes roll mark on inner wall, eliminates hidden problemssuch as stress cracking and can help achieve better piercing and rollingquality.
