Titanium equipment arrival acceptance 3-step list: no longer have to worry about receiving goods have problems

Published by Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd on 2026-08-01

After titanium equipment arrives, many factories simply check the appearance and directly enter the warehouse.Once the acceptance process is simplified, even titanium equipment purchased at a high price is easy to bury long-term hidden dangers.Shaanxi Qianyi Tuoda deeply cultivated titanium non-standard products rooted in Baoji Titanium Valley for 12 years, I have seen a large number of customers directly put into use, All kinds of faults appear after about one year of operation, image composite plate with insufficient multilayer thickness, Hardness of sealing surface is not up to standard, Problems such as weld cracking are common.Master 3 steps 9 acceptance action, 3 minutes to read this acceptance list, All kinds of risks in titanium equipment arrival acceptance can be avoided.

core conclusions, Titanium equipment acceptance cannot rely solely on visual inspection of appearance, Focus on verifying three contents, MTC Material Certificate in turn, Physical size and surface quality, Nondestructive testing and the reinspection report.Acceptance sequence cannot be changed at will. Reversing the sequence is easy to bury hidden dangers for subsequent equipment operation.

Step 1, Check MTC Material Certificate MTC is equivalent to titanium equipment product identification, Products lacking material certificates, No matter how high or low the quotation is, it is not appropriate to sign for it.A compliant MTC shall include six items: the first item, furnace batch number, which shall be traceable in the whole process;The second chemical composition, titanium content shall meet Ti≥99.5%, and the material designation shall be consistent with the requirements of drawings;The third mechanical property, tensile strength ≥370MPa;The fourth implementation standard, such as GB/T 9112, ASME B16.5 and other corresponding standards;The fifth test data, including PT, UT, RT related test report;The sixth item of data signature shall be stamped with the fresh seal of the manufacturer and the signature of the inspector.

Practical operation tips: if any of the six items in MTC is missing, the product can be rejected directly.Don't trust the scheme of supplementary data in the later stage, and supplement the material certification documents afterwards, there is a risk of false data.

Step 2, Verification of physical size, Surfaces and logos Material certification document parameters up to standard, Does not mean that the physical product is qualified, This step consists of three verification actions. Action one, retest size.Check outer diameter, wall thickness, length, DN nominal diameter and PN nominal pressure item by item according to drawings.There are three size prone to negative deviation, It is the key point of acceptance, flange wall thickness, Drawing marked 8mm, If the measured value is not less than 7.8mm, it is qualified., Tolerance control ±0.3mmWall thickness of pipe, drawing 3mm, measured not less than 2.9 mm;titanium steel clad plate, Drawing 3mm, Measured not less than 2.8mm, Shrinkage of clad thickness is a high frequency problem of acceptance. Action two, surface check.Inspect the surface with 10x magnification, Class III defects are recommended to be rejected, One crack, Even 0.5 mm microcracks are unacceptable2 scratches, pits, depth more than 0.3mm will not be accepted;Its oxidation discoloration, plate surface blue, black on behalf of processing overheating, prohibited to put into use. Action 3: Check product identification.Each piece of titanium equipment shall bear three marks, material trademark, As in TA2, Stamp or spray markProduct specifications, marked DN×PN and implementation standard number;The batch number of furnace shall correspond to the batch number on MTC material certificate one by one.The identification is vague and missing, and the signature can be refused.

Step 3, Review NDT and retest reports The test report is equivalent to the physical examination data of titanium equipment, Focus on verifying three types of reports.PT penetration testing is used for weld and product surface inspection, requiring 100% full coverage and no crack defects;UT ultrasonic testing is mostly used for composite plates and tubesheets, and the combined area of plates is not less than 98%.Hardness retest for sealing surface, measured hardness ≥180HV.

Practical tips, The test report shall be preferably issued by a third party organization, Reports from institutions such as Pune can be submitted, The report is accompanied by the qualification certificate number of the tester.Party A or supervision unit may not approve the simple manufacturer's self-inspection report.

5 common acceptance scams, procurement and quality inspection must pay attention to

Scam 1: MTC material certificate fraud.Common features are blurred seals, lack of inspector signatures, and misspelling of standard numbers.Verification method, you can contact the testing agency, telephone verification report authenticity. Scam 2: Composite plate multilayer thickness shrink.The drawing indicates that the multilayer is 3mm, but the actual measurement is only 1.5-2 mm.Verification method, using ultrasonic thickness gauge, each product sampled 3 to 5 points measurement. Scam 3: insufficient hardness of sealing surface.Annealed state TA2 hardness is only 150-170HV, can not reach 180HV use requirements.Verification method: use portable hardness tester to re-test on site, sampling 3 pieces per batch. Scam 4: Weld is not annealed.There is no annealing process record for butt weld data.verification method, Request furnace temperature curve records from supplier, The process is to keep the temperature of 550-600 DEG C for 1 - 2 hours. Scam 5: inferior brand, TA2 as TA10 supply.Drawing requirements TA10, field XRF detection of titanium molybdenum nickel element characteristic peak is not obvious.verification method, Portable XRF field component detection, TA9 contains palladium, TA10 contains molybdenum, nickel, Quickly identify the brand.

3 industry masters only know the hidden acceptance details

Detail 1: Inspection of PE film lining of wooden box.For titanium equipment transported by sea or long distance, PE protective film must be laid inside the packaging box and desiccant must be placed.Lacking lining protective film, salt fog corrosion titanium materials, arrived white spots appear on the surface. Detail 2: Parts are individually packaged.Titanium flange、titanium pipeThe pieces need to be packaged in a single vacuum bag.Multiple stacked packaging, transport bump easily cause surface scratches. Detail 3: Pipe head protection.titanium pipeMaterials, pipe fittings, flanges supporting plastic head, cover.Lack of protective cover, easy to accumulate rainwater and sediment inside the lumen, and additional cleaning procedures should be added before installation.
