Therefore, when looking at the house, we need to pay attention to these problems. It is not just the people who buy the house, but the house feng shui. Building a house is also a need to see, then how to look at the house feng shui problem? How to see the house lighting is good? Next, let me introduce you to the small series of the decoration home network.

First, how to look at the house Feng Shui

1, the house is too dark and feng shui is not good

The house must have windows and the windows must have a certain view. Some houses have almost no windows, and they are very dark; some houses have windows like this, but there is a wall in front of the window that covers the sun and blocks good luck. This kind of situation is not suitable in the wind and water, it will bring a lot of trouble to the family, it is easy to create a diaphragm between the loved ones, and the career is not smooth.

2, the left and right asymmetrical house is not good

China is symmetrical, and symmetry also means harmony. If the house is high and low, the fortune will not be good, just like the small sailing boat in the big waves, swinging. Speaking on the wind, Zuo Qinglong, right white tiger. If there is a very tall house on the right side of the house where you live, then your health needs to be taken care of. If you encounter such a house, you will have neither good fortune nor good health. People with heavy yang will become mediocre, and people with poor yang will live in danger.

Second, how to see the house lighting is good

1. The opening and depth of the apartment

If the opening is too small, it will affect the lighting and ventilation of the apartment. The room will appear darker. If the depth is too small, the opening is too large to be conducive to the insulation of the room and waste energy. The square type of the house can generally balance the lighting and ventilation. Therefore, the appropriate ratio of opening and depth can ensure the normal lighting and ventilation of the house and the stability of the indoor temperature.

2. House orientation

The house faces the direction facing the lighting surface, which will have certain influence on the lighting, ventilation, noise and energy saving of the building. The ventilation of the house must meet the basic requirements of people for air flow. Ensure the smooth circulation of indoor and outdoor air when opening doors and windows, especially during the hot summer months.

3. The windows of the house

Sunlight can only be illuminated through windows and balconies. In theory, houses with three sides of the east, south and west have good lighting effects. When the window is opened, the wind can be blown in, and the ventilation can be well realized. Some windows are relatively large, but the actual opening can be relatively small.

The feng shui problem of the house is that we all pay more attention to it, so we need to pay attention to this problem when buying a house. Then how to look at the house feng shui problem and lighting is good, I want to introduce the above small series, everyone also understands these issues. Well, if you still want to know more about decoration, please continue to pay attention to the decoration home Internet cafe.

Boiler Tube - for pressure equipment, used at higher temperatures

Standards and steel grades,
Tube sizes acc. to EN, DIN, BS, NF A, UNI, STN, ÄŒSN and PN-H standards,
Tube sizes acc. to GOST and TU standards,
Tube sizes acc. to ANSI standards,
Tube sizes acc. to ASME standards,
Precision tube sizes.

Boiler tube is made from heat resisting carbon and low alloyed steels which can withstand the load at high pressure and temperature. Boiler tube is used for parts of energy type equipment such as boilers, steam superheaters, steam pipelines, etc. The tubes are supplied as hot rolled or cold drawn. Specifications, dimensions and the steel grades are shown in a separate overview.
Boiler tube dimensions and tolerances

The tube dimensions range from 10.2 mm to 139.7 mm, from 26.9 mm diameter and the wall thickness from 2.6 mm and they supplied as hot rolled. The smaller diameter tubes and the thick wall tubes of larger diameters are supplied as cold drawn and subsequently they are heat treated. The tubes delivery in this condition happens only if there is an agreement upfront at the time of ordering the tubes. Based on an agreement it is possible to deliver boiler tubes with dimensions and tolerances according to the dimensional specifications for precision tubes. The tube dimensions meet the requirements of the following EN 10216-2, DIN 2448, BS 3059-1, BS 3059-2, BS 3602-1, BS 3604-1, NF A 49-211, NF A 49-213, UNI 4991, STN 42 5715, STN 42 5716, ÄŒSN 425715, ÄŒSN 42 5716, GOST 8732, PN-H 74252, ANSI B36.10, ASME B36.10. The detailed dimensional overview is shown in the tables according to EN, DIN, BS, NF A, UNI, STN, ÄŒSN and PN-H standards, GOST standards, TU standards, ANSI standards, ASME standards and standards for precision tubes.

Length of the boiler tube

Diameter (OD) [mm] Wall (WT) [mm] Length (L) [m]
OD < 60,3 5 – 6
OD => 60,3 WT < 7,1 5 – 6 or 10 – 14 after an agreement 22,4
WT => 7,1 5 – 6
Types of the length of supplied tubes: (a) random, (b) fixed ± 500 m, (c) exact + 15 / - 0 mm.

Boiler tube straightness

Straightness deviation for the whole length of a tube can not exceed value of 0.0015 x L. In conversion to the 1 meter length it can not exceed 3 mm.

Ends of the boiler tubes

The ends of the tubes are vertical to the longitudinal axis and are without burrs.

Condition of the tubes surface

The tubes condition corresponds to the requirements of appropriate standards, heat treatment to the way of tube manufacturing and chemical composition of steel.

Marking of the tubes and tube bundles

The tubes with the outside diameter up to 51 mm are marked with a label that is attached to the bundle. Larger tubes are marked at least at a one end of a tube by the necessary data.

Surface protection of the boiler tubes

While ordering, it is necessary to agree upon the way and means of temporary protecting the surface of the tubes during transportation and storing. The tubes may be supplied without temporary preservation of the surface, or with the preservation of the surface with an agreed upon preservative.

Packaging of the boiler tubes

The tubes are supplied in packages with a circular or hexagonal diameter with weight of 300 to 3500 kilograms. The tubes are bound with a steel band. It is possible to arrange wrapping to plastic sheet, burlap or to wooden crates.
