摘要： Pipelines with a control system and forced circulation of fluids through the annulus between an inner barrier and an outer cover of a pipe use a system configured to force circulation of fluids through the annulus. The pipe includes segments (T1, T2, T3, TN) joined together by means of connectors, wherein each segment of the pipe has an injector pipe (I1, I2, I3, IN) for injecting fluid into the annulus at a first end of the segment, and a return pipe (R1, R2, R3, RN) for removing fluid from the annulus at a second end of the segment.

摘要： A blown film of soil biodegradable aliphatic polyesters produced primarily from diacid and diol monomers. The diacid monomers may be of any type including succinic acid, adipic acid, and hexanedioic acid. The diol monomer may be of any type including ethylene glycol, propanediol, butanediol, and hexanediol. Commercial aliphatic polyesters produced from diacid and diol monomers include polybutylene succinate (PBS), polybutylene adipate succinate (PBAS), and polybutylene adipate (PBA). Comonomers may also be added. Such comonomers include chemicals with a single carboxylic acid, hydroxy, or amine moiety, which act as chain terminators, chemicals with three or more carboxylic acid, epoxy, and/or hydroxy moieties which, act as branching agents.

摘要： Hoses include a tube, a reinforcement layer disposed outwardly from the tube, and a cover layer disposed outwardly from the reinforcement layer. The cover layer may be based on a first elastomeric blend of a first chlorinated polyethylene and chlorosulphonated polyethylene, a first flame-resistant composition, and a peroxide/sulfur curing system. The tube may be based upon a second elastomeric blend of a second chlorinated polyethylene and ethylene vinyl acetate rubber, a second flame-resistant composition, and a peroxide curing system. The first flame-resistant package and the second flame-resistant package includes one or more ingredients selected from the group consisting of antimony oxide, zinc molybdate/magnesium silicate complex, magnesium aluminum hydroxy carbonate, and aluminum trihydroxide. In some aspects, the hoses meet the testing performance requirements of EN 45545-2, HL2/R22 category standard, and EN854 type 2TE standard.

摘要： Disclosed herein is a polyvinyl chloride (PVC) hose with a leak notification function. The PVC hose includes: an inner layer configured such that a fluid is transferred through a hollow; a reinforcing yarn layer wound around the inner layer, and configured to increase the pressure of the inner layer and restrain expansion; an intermediate layer formed through coating around the reinforcing yarn layer; a first electrode layer formed through coating around the intermediate layer, and provided with a first terminal; a partition layer formed through coating around the first electrode layer; a second electrode layer formed through coating around the partition layer, and provided with a second terminal; a high-density woven yarn layer processed around the second electrode layer; an outer coating layer formed through coating around the high-density woven yarn layer; and a leak detection device configured to determine whether there is a leak depending on whether current is conducted.
