At SIESA (Specialized Services and Imports), we offer advanced solutions in carbon steel pipes with interior coating, designed to meet the most demanding demands of various industries. These pipes combine the strength and durability of carbon steel with superior corrosion protection, ensuring optimal performance and long life.
Our pipes are equipped with an inner coating of advanced fluoropolymers and thermoplastics, including PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxyalkane), PVDF (polyvinylidene fluoride), ETFE (Tefzel) and PPL (polypropylene). These materials are optimized to withstand the most demanding conditions and allow the manufacture of special parts by rotational molding (PFA and Tefzel).
SIESA® coated pipes are the preferred choice for projects requiring maximum durability and environmental safety.
The SIESA® LAP JOINT makes pipe connection and handling easier with its ability to rotate, allowing for precise alignment and easy installation.
A SIESA® adjusting spool can have fixed or idler flanges and is essential in piping systems, allowing length adjustments for precise connections between a circuit.
A SIESA® Jacketed Reel is an advanced industrial solution for transporting fluids at controlled temperatures, used in processes where thermal efficiency and safety are essential.
Dismantling, supply and installation of seamless carbon steel pipe A-106, schedule 40, with A-105 Lap Joint flanges, Class 150#, in accordance with ANSI B16.5. The project includes A-234 body connections, A-105 fixed flanges, Class 150#, also under ANSI B16.5, all with PTFE and PFA interior coating. All material will be manufactured in accordance with ASTM F-1545, in various diameters, for use in a petrochemical complex.
What advantages do SIESA® reels have compared to steel?
Corrosion resistant, They withstand any chemical substance at any concentration up to 250°C. They require minimal maintenance costs and have a useful life of up to 30 years.
Are they safe to use?
Clear! Our manufacturing system is unique and efficient in which specialized machinery performs cold rolling to create the stub end, no more welding or manufacturing in the field that can reduce its quality, our method is carried out under the strictest quality standards in accordance with standards and specifications that ensure the best quality. ISO 9001 2015 quality system. Our products are subjected to tests that guarantee their quality and safety, in accordance with ASTM F-1545, a dielectric test is carried out at 20,000 volts.
What are our SIESA® pipes made of?
Our reels, like our coated valves and accessories, are made of a piece of carbon steel with an interior coating of fluoropolymers and thermoplastics that have the following properties:
PTFE: Polytetrafluoroethylene -20° to 500°F (-29° to 260°C)
PFA: Perfluoroalkoxyalkane -20° TO 500°F (-29° TO 260°C)
PP: Polypropylene -20° to 225°F (-29° to 107°C)
FEP: Fluorinated Ethylene Propylene −20° to 300°F (−29° to 149°C)
PVDF: Polyvinylidene Fluoride 0° to 275°F (-18° to 135°C)
HDPE: High Density Polyethylene -148° TO 194°F (-100° TO 90°C)
ETFE: Tefzel, Ethylene Tetrafluoroethylene -148° to 320°F (-100° to 160° C)
Founded in 1988 with the objective of helping the different branches of the industry to prevent and solve critical corrosion problems.
100% Mexican company, with vision for the future, dedicated to the supply of materials and engineering services to solve corrosion problems in industrial, residential and government processes.
