Straight seam steel pipe is a longitudinally parallel steel pipe. Usually divided into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe and so on. The straight seam welded pipe has a simple production process, high production efficiency, low cost, and rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe. A narrower blank can be used to produce a larger diameter pipe, and a blank having a different diameter can also be produced using a blank of the same width. However, compared with the straight seam pipe of the same length, the length of the weld seam increases by 30 to 100%, and the production speed is low.
Straight seam steel pipe main processing methods are:
Forged Steel: A method of pressure processing that uses the reciprocating impact of a forging hammer or the pressure of a press to change the blank into the shape and size we want.
Extrusion: It is the processing method of the finished product with the same shape and size. It is used to produce nonferrous metal materials. .
Rolling: A method of press machining in which a steel metal billet is passed through a gap (a variety of shapes) of a pair of rotating rolls, and the length of the material is reduced by the compression of the rolls and the length is increased.
Pulling steel: It is a method of processing that a metal billet (type, pipe, product, etc.) that has been rolled is pulled through a die hole to reduce the length of the section, and the length is increased.
Straight seam steel pipe use Straight seam steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid transport: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. Used for structural purposes: as a pile driving pipe, as a bridge; piers, roads, building structures, etc.

BMI Tape Measure

Introduction

BMI(Body Mass Index) is a person's weight in kilograms divided by the square of height in meters.

In general, BMI is an inexpensive and easy-to-perform method of screening for weight category, for example underweight, normal or healthy weight, overweight, and obesity.


About Materials and Shape of Case

The BMI calculator is ABS case, PVC coated fiberglass tape.
BMI tape measure has several kinds of case shapes-round shape, heart shape, and drip shape. Today we will introduce this round and biggest one for you.


About Language Version of Wheel Plate

This is the most popular English version.
We have Spanish version and other language versions.


About Tape Sizes

The tape both sides with 150cm, one side for male and the other side for female.
To check your waist size, the tape marked with 3 colors zones (green for healthy, orange for over weight, red for over obese)
There are 2 widths for the tapelines: 13mm and 7.5mm


About Usage

On the case, there is a wheel which can be rotate. Body height data in cm and inch marked on wheel, and weight data on the case, when we rotate the wheel, we can match the height and weight, then check the BMI arrow point to which section(there are 5 sections:underweight,healthy,overweight,obese and very obese)

For example, you are 160cm height and weight 55kgs, match them, then check the BMI arrow point to healthy.


BMI Categories

Less than 20: Underweight

From 20 to 25: HEALTHY

From 25 to 30: OVERWEIGHT

From 30 to 40: OBESE

More than 40: VERYOBESE
