TH3889B - How To Produce Inner Hume Tubes - Google Patents

Abstract

A method for producing an internally lined humped pipe, in which a humped pipe has a slit at one end with a diameter of large and the other end is a speak-at. The inner surface of this hump tube will Was lined with synthetic rubber pipes, the production method will consist of steps. The following 1) The synthetic rubber tube is inserted into the oars in the Hume tube by Both ends of the hose protrude from the humped tube at the end. The socket side and the end of the peak Then bring the cover to cover both ends of the rubber hose 2) Bring the medium that heats through the synthetic rubber hose to make the hose The rubber heats and weakens, then the fluid is introduced under compression pressure. Inside the synthetic rubber tube to push the expansion rubber tube to contact with the skin. in the hump tube until it is firmly attached, and then expels the fluid under force. Push this out of the synthetic rubber hose. 3) Remove the cap on the end of the tube. which is the socket, then cut out the synthetic rubber tube protruding from outside the socket of the pipe, lalhum discarded and brought a mold to compress it into the socket to compress the part of the synthetic rubber hose adheres firmly to the inner surface of the socket 4) Close the end of the pipe again and then the heating medium is brought in. to the synthetic rubber hose again to soften the rubber hose from Then bring the fluid under pressure into the synthetic rubber hose again. times to push the outer surface of the synthetic rubber tube to adhere firmly to the inner surface of the humped tube completely and then expel the fluid under pressure from the rubber hose 5) Make the end of the synthetic rubber hose protruding from the end Hume pipe On the peak, the hotter and weaker side then grabbed the protruding end. is folded outward to cover the end of the hum pipe and the outer surface of the pipe. Hume at Peak Ut

1. How to produce inner lining Hume pipe, this Hume pipe has one end, a socket with a large diameter and the other end is a peak up, the inner surface of the Hume. this Will be lined with synthetic rubber tubes The procedure consists of: a) a synthetic rubber tube is inserted inside a hume tube with a tip. Both sides of the hose protrude from the hume tube at the end of the socket. And the end of the peak at, then the cover is scabbed on both ends of the rubber tube. B) The heated medium is passed through the synthetic rubber tube. To heat the rubber tube and soften it, then the fluid Under pressure, presses inside the synthetic rubber hose to push the hose The rubber expanded into contact with the inner surface of the Hume tubing until it was almost firmly attached. Therefore expelling fluid under this pressure from the synthetic rubber tube c) Remove the cover on the side of the socket-outlet pipe and cut the rubber tube. Synthesize the protrusion outside the socket of the disposable hume pipe and reuse. The mold is pressed into the socket to compress the rubber tube section. Synthetic adheres tightly to the inner surface of the socket. d) Close the end of the synthetic rubber hose again and take the Medium that is heated into the synthetic rubber again to provide The hose softens, then the fluid under pressure is introduced into the Synthetic rubber hose again to push the outer cap of the rubber hose. Synthetically adheres tightly to the inner surface of all Hume tubes from Then chasing the fluid under pressure from the rubber tube e) Make the ends of the synthetic rubber hose protruding from the hume hose. The peak at hot and weakened, then the tip that was protruding. Folded outward to control the hume pattern pipe and the outer surface of the pattern pipe. Hume at Peakat 2. The method described in Clause 1 of the rubber hose. The synthetic rubber used is made from hard rubber, vinyl chloride, or polyurethane. Lee ethylene or polypropylene rubber 3. The method described in Clause 1, which the intermediary The heat that is mentioned in step (b) will be distant ethylene. Cole or hot steam 4. Method as described in Claim No. 1, which fluid Under the pressure mentioned there is a gauge pressure of 0.5-5 kg / cm2. 5. The method described in Clause 1, which the intermediary The heating medium used in the (d) procedure is the same as the medium. That heat that produces that heat used in step (b) 6. The method described in Claim No. 1, which the fluid Under the pressure mentioned used in step (d) is the same as that of a fluid Under pressure applied in section (b) (6 claims, 2 pages, 6 fig.)
