Types of Coated Pipe Fittings

SIESA® Coated Accessories

These fittings have interior coatings in PTFE, PFA, PVDF, PP and ETFE, with dimensions ranging from 2” to 12” (for larger diameters, please consult us). They can be presented as fittings with fixed flanges or rotating flanges (loose flanges).

Elbows

SIESA® coated elbows in 90° and 45° angles, made of carbon steel and coated with fluoropolymers and thermoplastics such as PP, PTFE, PFA and PVDF, are ideal for optimizing spaces and ensuring high chemical and anti-corrosion resistance.

Tees

SIESA® coated tees, made of carbon steel with anti-corrosion protection and internal coatings in fluoropolymers and thermoplastics such as PP, PTFE, PFA and PVDF.

crosses

SIESA® cross-shaped accessory, ideal for dividing the flow into three parts, made of steel with interior coating in fluoropolymers and thermoplastics, available in standard measurements or with reductions according to the needs of the project.

Reduced Flange

Highly durable connector that allows the union of pipes of different diameters, guaranteeing a safe and resistant connection.

Reductions

SIESA® concentric and eccentric reductions, made of carbon steel with fluoropolymer and thermoplastic coatings, guarantee an efficient and safe fit in reducing fluid flow in industrial piping systems.

Adjustment Spacers

The SIESA® Adjusting Spacer, manufactured for small lengths, is used for precise adjustments during the installation of fluoropolymer-coated pipes and fittings, ensuring optimal alignment.

Filtration Elements

The SIESA® strainer filter, available in “Y” type or basket type, is ideal for removing debris and solid particles in corrosive services, with an easy-to-maintain design that protects the system and extends the life of the equipment.

Diver Tube

The SIESA® dip tube is used for the safe and direct injection of raw materials into reactors, allowing drainage or feeding without risks of exposure, failures or leaks to the outside.

Expansion joints

The SIESA® dip tube is used for the safe and direct injection of raw materials into reactors, allowing drainage or feeding without risks of exposure, failures or leaks to the outside.

SIESA® Flexible Hose

The SIESA® dip tube is used for the safe and direct injection of raw materials into reactors, allowing drainage or feeding without risks of exposure, failures or leaks to the outside.

Peephole

The SIESA® sight glass, with anti-corrosion coating and borosilicate glass, offers a safe and reliable visual indication of fluid flow, ideal for applications in chemical, petrochemical, pharmaceutical and food plants.

Resin Trap

The SIESA® Resin Trap, designed to capture and retain resin particles in piping systems, ensures flow purity and protects equipment in critical industrial applications.

Advantages of SIESA coated pipe fittings

  • Durability and Strength:
    • Fittings coated with materials such as PTFE, PFA, and PVDF offer exceptional corrosion resistance, significantly extending the life of the facility, with an estimated life of up to 40 years for some coatings.
  • Chemical Compatibility:
    • Fluoropolymer coatings (PTFE and PFA) are highly resistant to almost all chemicals, including highly corrosive substances, ensuring broad compatibility in various industrial applications.
  • Reduction of Operating Costs:
    • By reducing internal friction and resisting corrosion, these fittings help minimize maintenance and operating costs, resulting in significant long-term savings.
  • Environmental Protection:
    • Double containment systems and high-quality coatings prevent the leakage of toxic and corrosive fluids, thus protecting the environment and reducing the risk of accidents.
  • Variety of Materials and Customization:
    • SIESA offers a wide range of coatings and materials (such as PTFE, PFA, PVDF) that can be tailored to the specific needs of the project.

Engineering, Dismantling, Supply and Installation of Pipes, Connections and Valves in different diameters coated with PTFE, PFA and POLYPROPYLENE.

SIESA has participated with basic engineering, detailed engineering, dismantling, supply and installation.

This project was supplied to an industrial chemical company with high exposure to handling dangerous and highly corrosive chemicals, the environment has a high level of humidity and direct exposure to UV rays.

SIESA® pipes provide maximum safety as they are manufactured from a carbon steel alloy with an external coating in epoxy paints of the highest quality and an internal coating of fluoropolymers that ensure the highest quality in the conduction of fluids.

What are the advantages of SIESA® coated accessories?

Our coated accessories are designed to make the best use of work spaces in a carbon steel alloy, with an exterior coating in epoxy paint with a glossy finish, highly resistant to corrosion, and an interior coating in fluoropolymers and thermoplastics that ensure the safe conduction of highly corrosive fluids.

The best product for saline climates and extreme temperatures, industries such as PEMEX, oil platforms, chemicals, petrochemicals and anyone that handles corrosive fluid products, considerably reducing maintenance costs and with a useful life of more than 30 years.

Are they safe to use?

Of course, our manufacturing system is carried out under the most judicious quality standards in accordance with norms and specifications that ensure the best quality. ISO 9001 2015 quality system
