Bellows thermowelded execution

Product catalog summary

Overview: The document provides technical specifications and guidelines for thermowelded bellows, which are stress-resistant and watertight covers. These bellows are constructed with PVC frames and fabric, joined by welding without the use of adhesives.

Specifications: The bellows are available in various shapes including vertical, transversal, and horizontal configurations. Key technical terms include maximum closure (PC), stroke (CS), and maximum opening (PA). The folds are made in heights ranging from 8 mm to 50 mm.

Technical Details: The document outlines the calculation methods for the number of folds and closed pack dimensions. It provides formulas for precise calculations, especially when a compact closed pack is required.

Materials: The bellows are made from various materials such as polyester, Nomex, and glass fiber, with coatings like PVC and PU. Each material has specific properties including oil resistance, abrasion resistance, and mechanical resistance. Temperature ranges for these materials vary, with some capable of withstanding up to 300°C for instant contact.

Assembly and Fixing: The document describes different assembly possibilities and fixing systems, including terminal flanges made of steel or PVC, which can be aligned with the bellow profile for quick fixing using Velcro strips.

Key Parameters: Important parameters include fold height (HP), welding height (HT), total welding height (HTT), fold thickness (SP), fabric thickness (ST), and frame thickness (STI). These parameters are crucial for customizing the bellows to specific requirements.

TERMOSALDATO bellows thermowelded execution telai frames tela fabric MATERIALI A PAGINA 16 MATERIALS ON PAGE 16 Soffietto termosaldato bellows thermowelded execution Sono coperture resistenti alle sollecitazioni. Ogni piega viene supportata da un telaio di pvc, il fissaggio tra telai e manto avviene tramite saldatura (senza collanti). Si realizzano, in questo modo degli elementi termosaldati resistenti alle sollecitazioni e a tenuta stagna. They are stress-resistant covers. Every fold is supported by a pvc frame, fixing between frames and shell executed by welding (without glues). In this way...
