Title:
COMPOSITE SHEET FOR COATING OF PIPING AND METHOD FOR SOUND INSULATION OF RESIN PIPING BY USING THE SHEET
Document Type and Number:
Japanese Patent JP3157645
Kind Code:
B2
Abstract:
PURPOSE: To obtain a composite sheet for covering a piping with high mechanical strength, good sliding properties and excellent workability by laminating a non-woven fabric or a woven fabric consisting of a uniaxially drawn body of a thermoplastic resin on one face or both faces of a cushioning sheet consisting of a thermoplastic resin.
CONSTITUTION: A composite sheet A for covering a piping is constituted by laminating a non-woven fabric or a woven fabric consisting of a uniaxially drawn body of a thermoplastic resin on one face or both faces of a cushioning sheet consisting of a thermoplastic resin. A resin pipeline is provided with sound insulation by inserting a composite sheet for covering a piping A constituted by laminating a non-woven fabric or a woven fabric consisting of a uniaxially drawn body of a thermoplastic resin on one or both faces of a cushioning sheet consisting of a thermoplastic resin in a gap between a resin pipe and an existing pipe in a resin piping technique. A composite sheet A for covering a piping with high mechanical strength, good sliding properties and excellent workability and a method for sound insulation of a resin piping using this sheet are obtd..
