摘要: An inflatable closing plug for pipes and a method of manufacturing same. The includes unitary balloon-like element elastic material, wire located on adhered to the outer surface element. extends from first end second element, has coefficient elasticity which is less than material can expand freely in radial direction bounded axial sense by longitudinal or wires, order permit sufficient pressure be achieved. To manufacture inflated predetermined pressure. At least one placed between its two ends, thereto.
