Tu 14-3-820-79. Seamless cold-deformed pipes of titanium-based alloys PT-1M, PT-7M
You are interested in TU 14−3-820−79 «Seamless cold-deformed pipes of PT-1M and PT-7M alloys. Technical specifications «from the supplier company AvecGlob? Here you will find interesting information on this topic.
Application area
These specifications apply to the supply of seamless cold-deformed pipes of PT-1M and PT-7M alloys.
Pipes are made of tube billets, delivered in accordance with TU 1−5-132−78,
bent and turned after hot redistribution or calibration in cold rolling mills.
Technical requirements for products include the following:
-The chemical composition of the pipe material is regulated by the technical specifications of TU 1−5-132−78 on the initial billet;
-On request of the customer pipes can be supplied in the initial state and without subsequent etching. It is allowed to supply pipes with polished surface or thermally processed in vacuum without etching;
-On the surfaces of finished pipes there should be no alpine layer;
-The surface of the pipes do not have scratches, cracks, sunsets, surface scratches and backdrops.
Pipes must comply with the «Delivery Terms» 01−1874−72. They are produced in length 1 — 8 m, external diameter 18 — 56 mm, with wall thickness from 1 to 6 mm.
Supplier — AvekGlob Company — offers, at reasonable prices from the manufacturer, seamless pipes of small sizes made of titanium alloys of PT-1M and PT-7M grades and corresponding to technical requirements of TU 14−3-101−79. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Mechanical characteristics, testing and acceptance of finished products
At room temperature, the mechanical properties of the pipes in question are:
| Alloy name | Limit of time resistance, MPa | Relative extension, % |
| PT-1M | 295… 500 | Not less than 27 |
| PT-7M | 480… 670 | Not less than 20 |
After manufacturing the pipes are subjected to 100% pneumatic tests at a pressure of at least 3.5 atm and 100% ultrasonic control of the macrostructure. A test is required for the hydrogen content, which in the chemical composition of the pipe material should not be more than 0.07%.
Supplier — AvekGlob Company — offers to purchase in the assortment various profiles of round tubes made of titanium alloys of PT-1M and PT-7M grades and corresponding to the technical requirements of TU 14−3-101−79. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
