無論是在各大工程中還是生產(chǎn)中，總會有剩余的方管，如果一直進(jìn)行堆積不加于防護(hù)就非常容易的被破壞，那么會對方管廠家造成嚴(yán)重的損失，所以在對方管進(jìn)行保管時(shí)，一定要注意合理的進(jìn)行保管。 保管方管的場地或倉庫，應(yīng)選擇在清潔干凈、排水通暢的地方，遠(yuǎn)離產(chǎn)生有害氣體或粉塵的廠礦。在場地上要清除雜草及一切雜物，保持方管干凈。

Whether in major projects or in production, there will always be surplus square pipes. If the accumulation is not added to the protection, it will be very easy to be destroyed, which will cause serious losses to the other side's pipe factory. Therefore, when keeping the other side's pipe, we must pay attention to reasonable storage. The site or warehouse under the custodian's control should be located in a clean and smooth drainage area, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed from the site and square tubes should be kept clean.

一些小型方管、薄鋼板、鋼帶、硅鋼片、小口徑或薄壁鋼管、各種冷軋、冷拔方管以及價(jià)格高、易腐蝕的金屬制品，可存放入庫;庫房應(yīng)根據(jù)地理?xiàng)l件選定，一般采用普通封閉式庫房，即有房頂有圍墻、門窗嚴(yán)密，設(shè)有通風(fēng)裝置的庫房;庫房要求晴天注意通風(fēng)，雨天注意關(guān)閉防潮，經(jīng)常保持適宜的儲存環(huán)境。

Some small square pipes, thin steel plates, steel strips, silicon steel sheets, small caliber or thin-walled steel pipes, various cold-rolled, cold-drawn square pipes and high-priced and corrosion-prone metal products can be stored in warehouses; warehouses should be selected according to geographical conditions, generally using ordinary closed warehouses, that is, warehouses with walls on the roof, close doors and windows, and ventilation devices; warehouses require attention to ventilation in sunny days, rainy days. Attention should be paid to damp proof and proper storage environment should be maintained.

在倉庫里不得與酸、堿、鹽、水泥等對方管有侵蝕性的材料堆放在一起。不同品種的方管應(yīng)分別堆放，防止混淆，防止接觸腐蝕;大型型鋼、鋼軌、辱鋼板、大口徑鋼管、鍛件等可以露天堆放;中小型型鋼、盤條、鋼筋、中口徑鋼管、鋼絲及鋼絲繩等，可在通風(fēng)良好的料棚內(nèi)存放，但必須上苫下墊。

No corrosive materials such as acid, alkali, salt and cement should be stacked together in the warehouse. Different kinds of square pipes should be stacked separately to prevent confusion and contact corrosion; large-sized steel, rails, disgraced steel plates, large-caliber steel pipes, forgings, etc. can be stacked in the open air; small and medium-sized steel, wire rods, reinforcing bars, medium-caliber steel pipes, steel wires and wire ropes, etc., can be placed in well-ventilated material shed, but must be upholstered and underlayed. 綜合來講，在對方管進(jìn)行保管時(shí)，存放環(huán)境是最重要的，只有存放環(huán)境有所保障，那么對于方管才能進(jìn)行很好的保護(hù)。

Generally speaking, the storage environment is the most important when the other party keeps it. Only when the storage environment is guaranteed, can the management be well protected.

方管執(zhí)行國家標(biāo)準(zhǔn)GBT 6728-2002 結(jié)構(gòu)用冷彎空心型鋼尺寸，外形，重量及允許偏差生產(chǎn)，是Q345B帶鋼經(jīng)過工藝處理卷制而成。方管在于它的材質(zhì)Q345B材料(低合金)生產(chǎn)加工而成與普通方管在原材料材質(zhì)(Q195,Q215,Q235)有很大的區(qū)別，一般是把Q345B帶鋼(低合金)經(jīng)過拆包，平整，卷曲，焊接形成圓管，再由圓管軋制成方形管然后剪切成需要長度常用長度為6米，12米量大可根據(jù)客戶要求定尺加工。一般小規(guī)格是50根每包，大規(guī)格在4根每包不等重量控制在3噸左右。方管在現(xiàn)貨方面以大規(guī)格居多在80MM*80MM-500MM*500MM，厚度在3MM-16MM。

The square tube is produced by cold-formed hollow section steel with dimension, shape, weight and allowable deviation for the implementation of national standard GBT 6728-2002. It is made of Q345B strip steel by coiling after process treatment. Square pipe is made of Q345B material (low alloy), which is very different from ordinary square pipe in raw material material material (Q195, Q215, Q235). Generally, Q345B strip steel (low alloy) is unpacked, flattened, crimped, welded to form round pipe, then rolled into square pipe by round pipe and cut into square pipe with the required length of 6 meters. The size of 12 meters can be fixed according to customer requirements. General small specifications are 50 per pack, big specifications are 4 per pack with unequal weight controlled at about 3 tons. In spot, square tubes are mostly of large size in 80MM * 80MM - 500MM * 500MM, thickness in 3MM - 16MM.

方管是方管的一個(gè)比較重要的類型的，在各種的市場發(fā)展和各種的應(yīng)用中都是在不斷地進(jìn)行增強(qiáng)的。因此的話建議廠家要多多注意方管的制作方法和質(zhì)量，這樣的話會有更多市場行情的!

Square management is an important type of Square management, which is constantly strengthened in various market developments and applications. Therefore, it is suggested that manufacturers should pay more attention to the manufacturing methods and quality of square tubes, so that there will be more market conditions!
