House fire on Keating in Chicago 1-12-13
"Here's a message from Josh Boyajian:
Chicago Fire Department responded to a Still alarm at 4600 S Keating this morning. Engine 34 arrived on scene and found a one-story residential structure with fire in the basement. Firefighters quickly deployed two lines to control the blaze. Tower 54 did an excellent job with roof operations, helping to prevent the fire from spreading further.
Josh captured some great photos of the incident, showing the firefighters in action and the aftermath of the fire. These images give a real sense of what the crew went through during this challenging call.
It’s always impressive to see how quickly the department responds and how well they work together under pressure. Thanks for sharing these shots, Josh — it's always valuable to get a first-hand look at what happens on the ground."

The Multilayered Pipe Co-extrusion Production Line is a highly advanced system capable of producing pipes with multiple layers, each serving a specific function.Â
Â
1. Plastic-Plastic Multilayer Co-extrusion Line
This line typically uses 2 to 5 extruders to produce pipes with layers of different plastics, such as PE/PPR/HDPE. The diameter range can vary from 20mm to 630mm, with a production speed of up to 80m/min.
The pipes produced have enhanced properties like high strength, corrosion resistance, and improved thermal insulation. The co-extrusion die head ensures uniform thickness of each layer.
Widely used in building water supply systems, heating systems, and industrial fluid transportation.
Â
2. Plastic-Metal Multilayer Co-extrusion Line
This line combines plastic and metal layers, such as stainless steel, to produce composite pipes. The diameter range is typically 16mm to 1000mm.
The metal layer provides strength and durability, while the plastic layer offers corrosion resistance and smooth inner surfaces. The production process includes precision roll forming and laser welding.
Ideal for water, hot water, and sanitary sewerage applications in industries requiring high-performance pipes.
Â
3. High-Barrier Multilayer Co-extrusion Line
Designed to produce pipes with high barrier properties, using materials like EVOH or PVDC. The diameter range can be from 16mm to 630mm.
These pipes have excellent gas and liquid barrier properties, making them suitable for transporting corrosive substances. The co-extrusion process ensures each layer is precisely controlled.
Commonly used in chemical, pharmaceutical, and food industries where contamination prevention is critical.
Â
4. Specialty Multilayer Co-extrusion Line
Customized for specific applications, such as medical or automotive pipes. The diameter range and production speed vary based on the application.
These lines can produce pipes with unique properties like UV resistance, flexibility, or specific surface textures. The production process includes advanced cooling and calibration systems.
Used in specialized fields like medical tubing, automotive air conveyance, and cable protection.
