3 / 8 * 0.049 304L Welded Stainless Steel ControL Line Tubing ASTM A269
Instructions for 3/8”Hydraulic control line
The 3/8“ hydraulic control line is mainly used to inject chemicals into oil and gas wells. That is, the 3/8” hydraulic control line is connected to the downhole chemical injection valve, and the descaling is performed through the 3/8“ hydraulic control line and the chemical injection valve. Chemical agent is injected from the surface into the oil tube at a certain depth down the well, which effectively removes the scaling of the oil tube and ensures the normal production of oil and gas fields.
Our products have complete specifications and can meet all working conditions. The outer diameter range of 304L Stainless steel control line tube we supply is from 1/8" to 1/2". All dimensions and corresponding parameters are listed in the table below, we can also customize it according to customers' requirement details.

Hydrostatic test for each coil and conform to ASTM standards and requested specifications.
The specification and length per coil can be customized according to customer’s requirements.
TIPTOP manufactures precision control line tubing for hydraulic and chemical injection of onshore and subsea oil and gas wells. The control line tubing is manufactured in a number of different product forms including seam welded and redrawn, seam welded and floating plug redrawn and seamless depending on the customer’s specification and application.
It can also be used for pressure control of surface ety valves and other surface valves, and various connection tubelines of large-scale equipment instrumentation control systems for oil and gas field drilling and oil production.
Our raw materials are all from the best manufacturers in China. Using high quality raw materials and advanced laser welding technology, our products have the characteristics of high strength, high plasticity, low cycle fatigue performance, high efficiency, low cost, ety and environmental protection.
Our main production process is generally as follows: Chemical composition analysis → Tensile testing → Hardness → Flattening → Flaring → Hydrostatic testing → Eddy current testing. Based on guaranteed quality, we can provide timely delivery and best service.
