Gr12 weld titanium exhaust pipe
GR12 (Ti-0.3Mo-0.8Ni, titanium-molybdenum-nickel alloy) Titanium
alloy is a corrosion-resistant titanium alloy. The foreign similar
grade Gr.12 (US) is a near-α developed to improve the crevice
corrosion performance of pure titanium. Alloy, which contains 0.3%
Mo and 0.8% Ni, not only strengthens the alloy, but also has good
resistance to crevice corrosion to high temperature, low pH
chloride or weakly reducing acid, and its corrosion resistance is
significantly better than pure titanium And close to Gr7 alloy.
Gr12 alloy also has good process plasticity and welding properties,
and has been widely used in chemical manufacturing equipment and
tanks. The alloy can be used in the annealed state, and the main
forms are sheet, rod, pipe, forging and wire Wait.

Test Specimens and Methods of Testing
1 The test specimens and the tests required by this ASTM B862
specification shall conform to those described in Test Methods and
Definitions A 370. Test specimens shall be cut from the welded pipe
except as specified in 13.2.
2 For pipe sizes over 14 in. outside diameter, a prolongation made
from the same heat of raw material and subjected
to all welding and heat treatment procedures as the ordered pipe
may be used for mechanical property testing instead of testing the
ordered pipe.
3 All routine mechanical tests shall be made at room temperature.
4. For referee purposes, Test Methods A 370, E 8, E 120, E 1409,
and E 1447 shall be used.
FAQ
1. Are you the manufacturing or trading company?
Real manufacturing company, started from 2001, nearly 20 years.
With 2 sales teams for foreign trading business, started from 2008,
more than 10 years experiences.
2. Do you have a dedicated R & D team? Can you design a product for
us?
We have a dedicated technical team responsible for research and
development. But most of titanium fittings are standard, we can
follow ASTM or other you asked.
3. Can you provide samples? Is there a charge?
Samples can be provided for a fee.
4. What is your payment method?
We can accept T / T, LC, trade assurance order from alibaba.com.
Samples are 100% prepaid. Orders for mass production are below 1000
USD, 100% prepaid, above 1000 USD, 30% prepaid, and 70% paid before
delivery.
5. How long is your delivery time?
Inventory samples: within 3 working days Products for bulk orders:
25-30 days under normal circumstances.
6. After-sales products, how to deal with problems?
Based on our statistics for each year, the probability of problems
with titanium products is around 0.8%. There are two main reasons
for the problem:
1) Among the products that have problems, 93% are misplaced in
pre-sales communication, and the product that the customer needs is
not really clear.
2) 5% is an unexpected situation and the extension of the
construction period.
3) 2% is the problem of transportation and packaging. During
long-distance transportation, the packaging is damaged and the
surface is damaged.
7. What is your company's response to the product in question?
1) Verify and blame for pre-sales communication issues.
Compensation is handled according to the proportion of liability.
2) We are 100% responsible for problems caused by damaged packaging
during transportation.
