The bending degree of galvanized square tube in Shenzhen profile manufacturers is implemented per meter

The bending degree of galvanized square tube in Shenzhen profile manufacturers is implemented per meter

1. The allowable deviation of the wall thickness of the galvanized square tube shall not exceed 10% of the nominal wall thickness when the wall thickness is not more than 10 mm, and the positive and negative 8% of the wall thickness when the wall thickness is greater than 10 mm, the angle and the welding Except for the wall thickness of the seam area.

2, the usual delivery length of galvanized square tube is 4000mm-12000mm, mostly 6000mm and 12000mm. The square tube allows the delivery of short and non-scheduled products of not less than 2000 mm, and can also be delivered in the form of an interface tube, but the interface tube should be removed during use. The weight of short and non-scheduled products shall not exceed 5% of the total delivery, and the square tube with theoretical weight greater than 20 kg/m shall not exceed 10% of the total delivery.

3. The bending degree of the galvanized rectangular tube shall not exceed 2 mm per meter, and the total bending shall not exceed 0.2% of the total length.

Folding edit this paragraph classification introduction

1. Square tube production process classification

Square tube according to the production process: hot-rolled seamless square tube, cold drawn seamless square tube, extruded seamless square tube, welded square tube. The welded square tube is further divided into: (a) according to the process - arc welded square tube, electric resistance welded square tube (high frequency, low frequency), gas welded square tube, furnace welded square tube (b) according to the weld seam - straight Seam welded square tube, spiral welded square tube

2, square tube material classification

Square tube according to material: ordinary carbon steel square tube, low alloy square tube. The carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc.;

Low alloy steel is divided into Q345, 16Mn, Q390, ST52-3 and so on.
As a Shenzhen building materials factory, Shenzhen Shengjinlong Iron & Steel Co., Ltd. mainly deals in all kinds of galvanized profiles, double-word steel, Gongjiao slot, angle iron wholesale, etc. Do you have the advantages of galvanized square tube? Below Shenzhen Shengjinlong Iron and Steel Co., Ltd. introduces you:
(1) High mechanical strength and high elongation;

(2) Good connection performance to ensure no leakage;

(3) Special sealing of the end face of the composite pipe;

(4) Traditional process installation for easy promotion;

(5) Good sanitary performance and can transport clean water;

(6) High temperature resistance, which can transport hot water and boiling water;

(7) It will not age and has a long service life;

(8) Good low temperature brittleness and small expansion coefficient;

(9) The price is low. The galvanized square tube is mainly used for drinking water supply pipes for drinking water, sea water conveying pipes, sewage conveying pipes, shipbuilding and other water pipes. The pipe connection method has a special snap ring connection, a groove (clamp) connection or a threaded connection, and the construction process is similar to the groove connection of the steel pipe and the threaded connection of the steel pipe.
The above is the advantages of the galvanized square tube introduced, I hope to help you, buy galvanized square tube, galvanized embedded parts to Shenzhen Shengjinlong Iron and Steel Co., Ltd., the price has a discount, welcome to consult!
