SLETPETRO's R & D team set up the coiled tubing reel joint project in February 2021. After the project was approved, the technical personnel went to the coiled tubing site to conduct all-round technical exchanges with customers and understand the application characteristics of products. After several rounds of technical discussions, the prototype was finally delivered on schedule. After the prototype was delivered and applied, customers put forward some rectification requirements for our products. Our technicians combined with theoretical design, learned from experience, finalized the scheme, which was approved by customers on site, and obtained orders for 5 sets of the products. SLETPETRO has been committed to providing customers with a wide range of products and services, keeping up with customer demand, to protect the operation and production of customers!
