Information

1Conditions of goods vehicle: the conditions of the truckShipment steel pipe of freight car should not be equipped with other items, especially the size and hardness in the transport, process may cause steel pipe damage, or during the process of shipping and the exercise of the steel tube moving objects around a car. At the time of shipment should not be used on the car to help or vehicle metal protrusions (such as warpage or uneven) part of the carriage, such carriage during transport need to use double supporting or edge cushion column, in order to prevent the steel tube in contact with the metal protrusions on the part of the car. 

2Support bars and pads:Do not use metal support bars. As steel pipes loaded on open trucks may come into contact with the side, edge protection should be provided. If the side is uneven, the edge of the side should be placed between the posts with a pad, and the pad should be imprisoned on the pad.

The support bar shall be of sufficient thickness to prevent the steel pipe from contacting the body or the body bulge. Generally, the thickness and width of the support bar should be no less than 2 In. (50mm) and no less than 4 In. (100mm). When the specification of steel pipe W6 float when loading; According to the steel pipe specification "20 pieces", other load methods except floating load are required to adopt the support of 2 inches (50mm) thick and 6 inches (150mm) wide.

Article in the use of support bars, all the support bars should be in the same horizontal plane, so that a single bearing is not too heavy load. Specifications in 6? In steel tubes up to 16 inches (excl. 16), what is the maximum horizontal error for the middle brace and end bearing? On the plane; Apply to & gt; 16 steel tube or D/ T (diameter/thickness ratio)& GT; 50. What is the maximum horizontal error for any steel pipe, article intermediate support and end bearing? On the plane. The gasket used for flat gasket should be fixed on the supporting member.

3 isolation.Seam type such as steel tube using the pressure loading, should use level of every article. The number and width of every article should comply withStress of the article, to support the requirements, the top of the article and the article should be put in the bottom of the bearing. For unilateral or bilateral trailer load, regardless of the size of the D/t, every article should be used in the overhanging trailer parts, parts and the overhanging steel band.

4 Loading and unloading equipment:When use the hook to the lifting pipe, should prevent hook pipe damage, and to be in the contact area (slope) and buffer lining material (e.g., non-metallic materials, such as rubber; Or metal materials, such as aluminium, but does not include any brass, copper, bronze and copper alloy). Hook should have enough width and depth, and adapt to the curvature of the steel tube inside. Unless the pipe for appropriate pipe protector, the rest should be on the steel hook mat elastic lining material, in order to protect the pipe end. Should avoid excessive impact load, lifting process and cause pipe body and pipe end appear local pit and round. When the steel tube in the process of hoisting could shake, necessary measures should be taken, chose not to damage the surface of the steel pipe spreaders, prevent the steel pipe surface damage. Use forklift at the time of shipment, fork should be round or add pad, appropriate to reduce the damage of steel pipe. 4.5 the pipe protection (trucks)Such as steel pipe end and the end of the car distance is less than 5 t1. 5 m), in order to prevent steel tube contact with car end plate, thickness should be placed at least for Lin (25 mm) of rough wood, and wood with car end plate fixation. Cars lined with wooden end plate is a suitable method of pipe protection. Loading, carriage side plate and steel tube should be at least leave ft (0.3 m) in the space, to facilitate loading and unloading.
