1, base plaster plaster marks 
The unevenness of the lap of the substrate will affect the aesthetic appearance of the decoration. Before the construction, it must be polished and polished with a sander. 
2, slotting matters needing attention When retrofitting additional water-supply pipes and wires, they should not be thrown horizontally in the wall surface, and should be thrown vertically. This is because horizontal damage has a great deal of damage to the wall, and it is very resistant to earthquakes and strength. It can only be thrown vertically and horizontally. Can't exceed 3-5 cm. If the slot is deep, it is easy to hit the steel in the wall and saw the steel bar broken. If the slot is shallow, it will be easy to bulge in the future. 
3, wall iron nail head Before the construction coating, nails should be cut out and knocked off the wall, and then the anti-rust paint should be used to treat the nail head. 4, material inspection First of all, we should pay attention to the behavior of the foreman to steal the column, or the material provided by the company, and then use additional materials to fill up the empty, once there is a problem, maintenance will be unclear after the sale. In addition, the classification of materials placed to avoid pollution, the formal decoration company will generally put the project schedule and supporting tools placed in a prominent position, the decoration site is also relatively clean. Decoration materials should be placed in categories and materials that are easily contaminated with each other should be placed separately. 5, crack inspection The construction of the wall often runs through the entire process of the renovation. If there is a wall of wood or modeling, it will be entered in the early stage of construction. If only the paint is painted, it will start work in the middle and later stages. But for the construction of the wall, the painting of the paint often goes through many procedures such as puttying, sanding, brushing, primer, etc. If it is not carried out in strict accordance with the construction specification, if the brushing is not in place, or if it does not wait until the previous If a process is dry enough to carry out the next process, it will be prone to wall cracks and cracks. 6, check whether there is emptying the substrate, the phenomenon of cracks Hollow wall will seriously affect the adhesion of the coating, etc., usually by visual inspection, tapping, hard carving, hand wipe and other methods. The phenomenon of empty drums must be completely eradicated, and repairs should be carried out by applying matching putty to repair or leveling or cement mortar with the same proportion as the wall mortar in accordance with the same construction method of the wall to ensure uniform absorption of the coating and no marks.

We can produce the lower-temperature Steel Pipe according to the ASTM A333 and ASME SA333 standards, and the and the production diameter from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We have been sold the GR.6 steel pipe about 20000 tons to date and the property of -45℃ impact value is about 100J, better than the standard`s requirements.
Yangzhou Chengde has the full capability to do every test in-house, from mechanical testing, chemical analysis, PMI, UT/Hydrotest etc. Chengde`s lab is qualified to ISO 17025 and CNAS standard, being proven the repeatability of accurate testings.
Each alloy pipe is subject to PMI before dispatch. The INNOV-X system performs non-destructive chemical analysis via simultaneous detection and quantification of fluorescent x-rays of multiple elements in test sample.
