201 Stainless Steel Sink 202 Stainless Steel Gutter Argon Arc Welding For Tableware

Company introduction:

Our company is a stainless steel plate, coil and stainless steel seamless pipe, welded pipe production and processing of large spot sales company, at the same time agent stainless steel bar, Angle steel, channel steel, etc., its product quality excellent, marketing throughout the country.  Over the years has been committed to the promotion and sales of stainless steel products, perennial distribution of Shanxi Taiyuan Iron and Steel, Shanghai Baosteel,Gansu Jiusteel, Kunshan Dageng, Shanghai Klup, Ningbo Baoxin, Guangzhou Lianzhong, Zhangjiagang Pohang, and other major steel stainless steel. And major steel mills to establish a long-term friendly relations of cooperation. At the same time also operate stainless steel bars, profiles, pipes and the whole plate dismantling business. Stainless steel plate products sales materials are:  SUS201, 202, 304, 316L, 316Ti, 321, 304L, 441, 444, 436, 439, 430, 409L, 410s, 309s, 310S, 904L , 2205, 2507 and other stainless steel materials, products are mainly used in chemical equipment, water treatment equipment, elevators, tableware, kitchen equipment, solar water heater, mechanical equipment, pressure vessels and other industries. Special processing: according to customer's specified open size.  

Possibility of water leakage:

Gutter is the whole bend, itself will not leak, the possibility of leakage includes: 

1) If the use of domestic general color plate, of course, it is easy to rust for a long time.  When using 2mm~3mm steel plate to do gutter, generally use antirust paint, can also be electrogalvanized or hot-dip galvanized.  Of course with Stainless steel is good, but the price...  .  BHP's color plate is good for corrosion protection.  If the requirements are strict, it is recommended to use stainless steel (1mm) inside the gutter, and still use color plate outside the gutter.  The use of more than 1mm plate gutter seems heavy, not light steel.  The outer gutter does not need to be sloped, while the inner gutter can be sloped by adjusting the length of the sling with a spacing of 500.  

2) The lap of the gutter may leak.  Generally speaking, this possibility is not large, as long as the lap length is sufficient, the sealant can be avoided evenly.  Gutter lap joints are welded.  (for welding damage to the coating should be taken treatment measures) the disadvantage of this scheme is that it is difficult to solve the problem of water caused by the deflection of the gutter!  There must be some deflection, unless pre-bending, only slope finding measures should be taken, and should be less dense slope finding materials.  It is recommended to choose more than 2.5mm steel plate production!  Gutter can replace eaves purlin, even contact beam!  

3) The gutter drains the water.  This basically is gutter size design is not enough, or downpipe blocked, do not close practice problem, can be prevented by increasing overflow mouth.  Caigang gutter needs on-site docking.  Usually, the corrosion of color steel plate starts from the incision and hole, and the ordinary rivet will rust, (the corrosion of the color plate incision is indeed a problem.  However, if the substrate is aluminum-zinc plated, there will be a compensation effect of battery reduction, which can better reduce the corrosion problem here.  Especially out of the heart easy to lead to leakage!  In theory, the surface corrosion resistance of color steel plate is indeed better than ordinary steel plate, but it is too thin, once it begins to rust immediately will lead to leakage.  The common gutter is not;  Party A also agrees with this point on this issue.  Therefore, in the selection of the scheme is also biased to the ordinary steel plate gutter (especially in the 6m column distance).  As for the strength, construction, but also take it as a construction channel, it can be seen that the stiffness of the ordinary gutter is better than the color plate gutter.  

Specification:

Stainless steel gutter welding using argon arc welding, welding rod with the same gutter of the same material of stainless steel wire, diameter can be the same thickness.  Commonly used is 1mm.  Before the formal welding, welders should be organized to test welding, qualified before the start of batch welding, welding at the same time, it is best to designate a special person to carry out, at the same time, arrange an auxiliary worker to cooperate with the operation, in order to improve the main production efficiency.  After the welding of the drop mouth, the area should also be properly hit the lower part to facilitate drainage.  Stainless steel electrode if there is sand and other pollution must be cleaned before use.  Because stainless steel cullis adopt folding processing molding, size deviation phenomenon inevitably exist, so the gutter in before sending the response to the thorough check, will be joint gap adjustment to a minimum as far as possible, before welding with welding spot welding is fixed, then by welding, welding according to the innate groove, welding cullis side then.  If possible, test row can be carried out. According to the situation of test row, it can be numbered and then hoisted to minimize the welding workload and ensure the engineering quality.  If the gap is too big to be fully welded with the welding wire, the leftover material can be used for splice. Attention should be paid to the surrounding welding at the splice, and the weld at the edge and corner should be full without leakage welding.
