How to buy iron products

When choosing a wrought iron product, you have to sit and try it yourself and see if there is any squeaking when shaking or when the weight is too heavy; see if the solder joints at the solder joints are firm. In the iron making process, it needs to be treated with oil, dirt, rust, and rust before it becomes a home decoration product. Therefore, when selecting, care should be taken to ensure that the surface is smooth and clean. Good wrought iron furniture is often produced by hand. This kind of product is of relatively pure material, with low carbon content, and its products are delicate; the welding points are smooth and firm, the furniture frame shape is symmetrical and coordinated, the surface is painted, and the paint is painted. Furniture is easy to clean. In addition, you should ask whether it has been treated with moisture. Moisture-prone metal oxides (such as iron, etc.) are not suitable for home use in high-humidity areas. Paint furniture, to ensure that the film does not fall off, wrinkle-free skin, no significant sag, no flaws, no bumps and scratches. No cracks or open seams are allowed on the wall of the steel pipe. There is no obvious wrinkle at the bend, and there must be no edge, burr and corners at the mouth of the pipe.

The riveting of metal parts and steel pipe must be firm and loose. Rivet caps should be smooth, flat, no burrs, and no bruises.

When handling metal furniture, avoid scratching and scratching the surface protective layer. Do not place metal furniture in a damp corner. Keep it dry and ventilated to prevent rust.

Maintenance Tips: Always wipe the furniture with a damp cloth and a mild detergent. After the dust has been contaminated, just brush the brush along the crevice with a soft brush, and wipe it with a damp, soft cloth. Do not use in wet conditions as much as possible, and pay attention to waterproof and moisture proof. If spots appear to be faded on the surface, paint should be repaired in time to avoid affecting the overall appearance of the product.

Pressure Sequence Valves

Sequence Valve is different from a Relief Valve in that the spring chamber is vented directly to atmosphere instead of to the outlet port on the valve. This allows full pressure to appear on both cylinders when they stall, instead of the pressure having to divide between them.
