3 / 8 Inch Alloy 625 Seamless Stainless Steel Control Line Tubing ASTM B704
Alloy 625 is a nickel-base alloy used both for its high strength and outstanding aqueous corrosion resistance. The strength of alloy 625 is primarily a solid solution effect from molybdenum and columbium. Alloy 625 has excellent weldability and is frequently used to weld AL-6XN® alloy. Matching filler metals are also used to join dissimilar metals.

Tiptop is specialized in providing alloy steel coiled tube, alloy steel control line, alloy steel continuous tube.
Seamless control lines are used in SCSSV, Chemical Injection, and Advanced Well Completions. Seamless tubes provide another tubing solution for our customer's complex well designs. The most common uses for Seamless line tend to be shorter length applications whereby no orbital welds are required.
Application:
Down hole tubes
Subsea umbilical’s
Process constructions
General control system
Steam supply lines
Gas transport lines
Instrumentation
Quality Control:
Hydrostatic test for each coil and conform to ASTM standards and requested specifications. The specification and length per coil can be customized according to customers’ requirements.
With high pressure and super length from 1/8” to 1/2” OD and a variety of wall thicknesses in loose bulk wound coils or reeled on wooden drum. These products are mainly applied in petroleum industry, chemical industry, shipbuilding, natural gas, and etc.
