Order details:

　　Recently, ETANG successfully delivered a batch of critical products—10 pieces of 6-meter-long Blast Joint. This delivery fully met the customer's stringent requirements for ultra-long dimensions and extreme operating conditions.

　　Both the internal and external surfaces of the products have undergone phosphating treatment. This process significantly enhances the corrosion resistance and wear resistance of the products, ensuring longer service life and higher operational reliability in complex downhole environments. The product’s internal and external precision meets the high standard of Ra 1.6μm, ensuring the sealing performance and assembly consistency of the components in high-pressure fluid environments. ETANG guarantees that each product undergoes a drift test to ensure the internal bore is completely unobstructed, fully meeting operational requirements.

　　The delivered Blast Joints will serve the customer's critical project, and their performance will provide assurance for the smooth implementation of the project. ETANG remains committed to leveraging advanced process technologies and stringent quality control to support customers in tackling the most complex downhole challenges.
