Tu 14-3-161-73. Pipes seamless of small sizes from alloys 1М and ВТ1-00. Technical conditions.

Are you interested in THAT 14−3-101−73 «seamless tubes of small sizes from alloys PT-1M and VT1−00. Technical conditions» from the company — supplier Alekhlas? Here you will find interesting information on this topic.

Scope

These specifications relate to cold-worked seamless tubes of small sizes, which are made from titanium alloys from alloys PT-1M and BT1−00.
The original billet is hot-rolled pipe, which comes on the other 1−5-132−78. The deformed workpiece is mechanically pre-processed and cleaned from traces of high temperature oxides.

Technical requirements for the products include the following:

-The chemical composition of the pipe material is regulated by the technical conditions TU 1−5-132−78 on the original billet;

-On customer’s request pipes can be supplied as heat treatment and subsequent etching;

-On the surfaces of the finished pipe must be alferovsky layer;

-The surface of the pipes does not have scratches, cracks, sunsets, surface scratches and satnav.

Chemical composition and size range of the tubes produced are given in the table:
